[PMID: 39122962 DOI: 10.1038/s41429-024-00766-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 07/21/2024] [Accepted: 07/26/2024] [Indexed: 08/12/2024]
Abstract
A new actinomycete strain, ODS25T, exhibited antimicrobial activity against Bacillus subtilis, Kocuria rhizophila, Staphylococcus aureus, Staphylococcus epidermidis, Candida albicans, Candida tropicalis, was isolated from the ants, Odontomachus simillimus, collected from National Science Museum Thailand, Pathum Thani, Thailand. A polyphasic technique was used to characterize the taxonomic position. The morphological and chemotaxonomic properties of the strain are typical of members of the genus Streptomyces. Strain ODS25T contained ll-diaminopimelic and glucose in the whole-cell hydrolysate. The major cellular fatty acids were iso-C16:0, iso-C15:0, and anteiso-C15:0. The polar lipids were phosphatidylethanolamine, phosphatidylinositol mannosides, phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, three unidentified phospholipids, three unidentified amino lipids and two unidentified lipids. The menaquinones were MK-9(H6), MK-9(H8), and MK-9(H4). The G + C content of the genomic DNA was 71.3%. The 16 S rRNA gene sequence analysis demonstrated that the strain had the highest similarity to Streptomyces lusitanus NBRC 13464T (98.07%) but shared the phylogenetic neighbour with Streptomyces sulfonofaciens JCM 5069T. Both digital DNA-DNA hybridization and average nucleotide identity values among strain ODS25T and its associated Streptomyces type strains fell within the values lower than the threshold for differentiate the strain to the same species. Based on the phenotypic characteristics and genotypic distinctiveness, strain ODS25T is considered a novel species within the genus Streptomyces, for which the name Streptomyces odontomachi sp. nov. is proposed. The type strain is ODS25T (=TBRC 16204T=NBRC 115862T).

Abstract
Three novel mycelium-forming actinobacteria, designated OC33-EN06T, OC33-EN07T, and OC33-EN08T, were isolated from wild orchid (Aerides multiflora Roxb), collected from a hill evergreen forest in Northern Thailand. Strains OC33-EN06T and OC33-EN07T showed the highest 16S rRNA gene similarity with Actinomycetospora lutea TT00-04T, 99.17 and 99.45%, respectively. Strain OC33-EN08T showed high similarity with four species, namely 'Actinomycetospora termitidis Odt1-22T' (99.37%), Actinomycetospora chiangmaiensis DSM 45062T (99.02%), Actinomycetospora corticicola 014-5T (99.02%), and Actinomycetospora soli SF1T (98.81%). Comparative genome analysis of OC33-EN06T, OC33-EN07T, and OC33-EN08T with the closely related type strains showed that average nucleotide identity (ANI) based on blast, ANI based on MUMmer, and average amino acid identity values were less than 95% and the digital DNA-DNA hybridization values were less than 70%, all below the thresholds for species demarcation. The digital G+C content of OC33-EN06T, OC33-EN07T, and OC33-EN08T were 74.5, 74, and 74 mol%, respectively. These three strains developed bud-like chains of non-motile cylindrical spores with a smooth surface. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, arabinose, and galactose. The predominant menaquinone was MK-8(H4). The phospholipid profile included phosphatidylcholine, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and phosphatidylinositol. Based on comparative analysis of genotypic, phenotypic and chemotaxonomic data, strains OC33-EN06T (=TBRC 18349T=NBRC 116543T), OC33-EN07T (=TBRC 18350T=NBRC 116544T), and OC33-EN08T (=TBRC 18318T=NBRC 116542T) represent the type strains of three novel species of the genus Actinomycetospora for which the names Actinomycetospora aeridis sp. nov., Actinomycetospora flava sp. nov., and Actinomycetospora aurantiaca sp. nov., are proposed.

Description of Streptomyces siderophoricus sp. nov., a promising nocardamine-producing species isolated from the rhizosphere soil of Mangifera indica. J Antibiot (Tokyo) 2024:10.1038/s41429-024-00763-x. [PMID: 39054393 DOI: 10.1038/s41429-024-00763-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 06/30/2024] [Accepted: 07/04/2024] [Indexed: 07/27/2024]
Abstract
An actinomycete, designated strain CH9-7T, was isolated from the rhizosphere soil of Mangifera indica. The morphological and chemotaxonomic properties, such as the production of spiral spore chains and the presence of LL-diaminopimelic acid in the peptidoglycan, showed that it belongs to the genus Streptomyces. Based on the 16S rRNA gene analysis, it was confirmed that strain CH9-7T was a member of the genus Streptomyces and revealed 99.9% 16S rRNA gene sequence similarity to its closest relative strains, Streptomyces lydicus NBRC 13058 T and Streptomyces chattanoogensis NBRC 12754 T. Although the strain showed high 16S rRNA gene sequence similarity values, however, genome relatedness indexes exhibited that the average nucleotide identity based on the MUMmer (ANIm) algorithm, the average amino acid identity (AAI), and the digital DNA-DNA hybridization values between strain CH9-7T and its closest phylogenomic relatives were below the threshold values for delineation of a novel species, (ANIm ranging from 87.5 to 88.6, AAI ranging from 80.6 to 84.6, and dDDH ranging from 28.4 to 31.7), respectively. A taxonomic position of strain CH9-7T in the phylogenomic tree showed that the closest relative strain was S. lydicus NBRC 13058 T. The comparative phenotypic studies between strain CH9-7T and its closest relatives revealed that strain CH9-7T could be classified as a novel species of the genus Streptomyces. Thus, the name Streptomyces siderophoricus sp. nov. is proposed for the strain. The type strain is CH9-7T ( = TBRC 17833 T = NBRC 116426 T). The chemical investigation led to the isolation of four known compounds (compounds 1-4). Among these compounds, compound 1 was identified to be nocardamine, a promising bioactive substance.

Exploring the antimicrobial and antioxidant properties of Lentzea flaviverrucosa strain E25-2 isolated from Moroccan forest soil. Front Microbiol 2024; 15:1429035. [PMID: 39104582 PMCID: PMC11298423 DOI: 10.3389/fmicb.2024.1429035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Accepted: 07/05/2024] [Indexed: 08/07/2024] Open
Abstract
The alarming rise in antimicrobial resistance (AMR) has created a significant public health challenge, necessitating the discovery of new therapeutic agents to combat infectious diseases and oxidative stress-related disorders. The Lentzea flaviverrucosa strain E25-2, isolated from Moroccan forest soil, represents a potential avenue for such research. This study aimed to identify the isolate E25-2, obtained from soil in a cold Moroccan ecosystem, and further investigate its antimicrobial and antioxidant activities. Phylogenetic analysis based on 16S rRNA gene sequences revealed the strain's classification within the Lentzea genus, with a sequence closely resembling that of Lentzea flaviverrucosa AS4.0578 (96.10% similarity). Antimicrobial activity in solid media showed moderate to strong activity against Staphylococcus aureus ATCC 25923, Bacillus cereus strain ATCC 14579, Escherichia coli strain ATCC 25922, Candida albicans strain ATCC 60193 and 4 phytopathogenic fungi. In addition, ethyl acetate extract of this isolate demonstrated potent antimicrobial activity against 7 clinically multi-drug resistant bacteria. Furthermore, it demonstrated antioxidant activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals, as well as a significant increase in ferric reducing antioxidant power. A significant positive correlation was observed between antioxidant activities and total content of phenolic compounds (p < 0.0001), along with flavonoids (p < 0.0001). Furthermore, gas chromatography-mass spectrometry (GC-MS) analysis revealed the presence of amines, hydroxyl groups, pyridopyrazinone rings, esters and pyrrolopyrazines. The Lentzea genus could offer promising prospects in the fight against antibiotic resistance and in the prevention against oxidative stress related diseases.

Abstract
Two novel actinobacteria, designated as LP05-1T and LP11T, were isolated from the lichen Pyxine cocoes (Sw.) Nyl. collected in Bangkok, Thailand. Genotypic and phenotypic analyses revealed that both strains represented members of the genus Streptomyces. The 16S rRNA gene of LP05-1T showed the highest similarity to the genome of Streptomyces gelaticus (98.41 %), while the 16S rRNA gene of LP11T was most similar to that of Streptomyces cinerochromogenes (98.93 %). The major menaquinones in LP05-1T were MK-9(H8), MK-9(H6), MK-9(H4) and MK-9(H2), and in LP11T, they were MK-9(H8) and MK-9(H6). Both strains exhibited the major fatty acids iso-C15 : 0, anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0, with LP05-1T also possessing iso-C17 : 0. The polar lipids of LP05-1T included phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unidentified lipid, while those of LP11T consisted of phosphatidylethanolamine, lyso-phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unidentified aminolipid and an unidentified glycolipid. The digital DNA-DNA hybridisation (dDDH) and average nucleotide identity (ANI) values indicated that both strains are distinct from each other with values below 70 and 95 %, respectively. dDDH, ANI by blast (ANIb) and ANI by MUMmer (ANIm) values between LP05-1T and its closely related type strains were 26.07-26.80 %, 81.24-82.01 % and 86.82-86.96 %, respectively, while those for LP11T and its closely related type strains were 30.70-31.70 %, 84.09-85.31 % and 88.02-88.39 %, respectively. The results of the taxonomic investigation, including dDDH and ANI values, indicate that LP05-1T and LP11T are novel type strains of two novel species within the genus Streptomyces. The names proposed are Streptomyces pyxinae sp. nov. for strain LP05-1T (=TBRC 15494T, =NBRC 115434T) and Streptomyces pyxinicus sp. nov. for strain LP11T (=TBRC 15493T, =NBRC 115421T).

Abstract
Strain Odt1-22T, an insect-derived actinomycete was isolated from a termite (Odontotermes formosanus) that was collected from Chanthaburi province, Thailand. Strain Odt1-22T was aerobic, Gram-stain-positive, and produced bud-like spore chain on the substrate hypha. According to chemotaxonomic analysis, strain Odt1-22T contained meso-diaminopimelic acid in peptidoglycan and the whole-cell hydrolysates contained arabinose, galactose, glucose, and ribose. The major menaquinone was MK-8(H4). The diagnostic phospholipids were diphosphatidylglycerol, hydroxyphosphatidylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. Phylogenetic analysis based on 16 S rRNA gene sequence revealed that strain Odt1-22T was identified to the genus Actinomycetospora and showed high similarity values with A. chiangmaiensis DSM 45062 T (99.24%), A. soli SF1T (99.24%) and A. corticicola 014-5 T (98.17%). The genomic size of strain Odt1-22T was 6.6 Mbp with 73.8% G + C content and 6355 coding sequences (CDSs). The genomic analysis, strain Odt1-22T and closely related species A. chiangmaiensis DSM 45062 T, A. soli SF1T and A. corticicola DSM 45772 T displayed the values of average nucleotide identity-blast (ANIb) at 83.7-84.1% and MUMmer (ANIm) at 86.6-87.0%. Moreover, the results of digital DNA-DNA hybridization values between strain Odt1-22T and related Actinomycetospora species were 45.8-50.5% that lower than the threshold value of commonly used to delineate separated species level. On the basis of phenotypic, chemotaxonomic, and genotypic data, strain Odt1-22T represented a novel species within the genus Actinomycetospora, for which the name Actinomycetospora termitidis sp. nov. is proposed. The type strain of the species is Odt1-22T (= TBRC 16192 T = NBRC 115965 T).

Antimicrobial potential of Streptomyces coeruleofuscus SCJ isolated from microbiologically unexplored garden soil in Northwest Morocco. Sci Rep 2024; 14:3359. [PMID: 38336871 PMCID: PMC10858231 DOI: 10.1038/s41598-024-53801-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 02/05/2024] [Indexed: 02/12/2024] Open
Abstract
Research on microorganisms in various biotopes is required to identify new, natural potent molecules. These molecules are essential to control the development of multi-drug resistance (MDR). In the present study, a Streptomyces sp., namely SCJ, was isolated from a soil sample collected from a Moroccan garden. SCJ isolate was identified on the basis of a polyphasic approach, which included cultural, micro-morphological, biochemical, and physiological characteristics. The sequence of the 16S rRNA gene of the SCJ strain showed 99.78% similarity to strains of Streptomyces coeruleofuscus YR-T (KY753282.1). The preliminary screening indicated that the SCJ isolate exhibited activity against Candida albicans ATCC 60,193, Escherichia coli ATCC 25,922, Staphylococcus aureus CECT 976, Staphylococcus aureus ATCC 25,923, Bacillus cereus ATCC 14,579, Pseudomonas aeruginosa ATCC 27,853, as well as various other clinical MDR bacteria and five phytopathogenic fungi. The ethyl acetate extract of the isolated strain demonstrated highly significant (p < 0.05) antimicrobial activity against multi-resistant bacteria and phytopathogenic fungi. The absorption spectral analysis of the ethyl acetate extract of the SCJ isolate obtained showed no absorption peaks characteristic of polyene molecules. Moreover, no hemolytic activity against erythrocytes was observed in this extract. GC-MS analysis of the ethyl acetate extract of the SCJ isolate revealed the presence of 9 volatile compounds including 3,5-Dimethylpyrazole, and pyrrolizidine derivatives (Pyrrolo[1,2-a]pyrazine 1,4-dione, hexahydro-3-(2-methylpropyl)), which could potentially explain the antimicrobial activity demonstrated in this study.

Abstract
A novel lichen-derived actinobacterium, designated Pm04-4T, was isolated from Pyxine cocoes (Sw.) Nyl. lichen collected from Chaiyaphum, Thailand. A polyphasic approach was used to describe the taxonomic position of the strain. The strain had morphological and chemotaxonomic properties similar to members of the genus Actinoplanes. It produced sporangia on the substrate mycelia. Meso-diaminopimelic acid, galactose, glucose and mannose were detected in the whole-cell hydrolysate of the strain. The major menaquinone was MK-9(H4). The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. The predominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. Strain Pm04-4T showed the highest 16S rRNA gene sequence similarity to Actinoplanes akusuensis TRM 8003T (99.0 %). In the phylogenomic tree, strain Pm04-4T was positioned close to A. aksuensis TRM88003T, A. maris M416T, A. polyasparticus TRM66264T, A. hotanensis TRM88002T, A. abujensis DSM 45518T, A. bogorensis NBRC 110975T, A. brasiliensis DSM 43805T, A. lichenicola LDG1-01T and A. ovalisporus LDG1-06T. The average nucleotide identity and digital DNA-DNA hybridization values between strain Pm04-4T and its closely related neighbours were below the threshold values for describing new species. Moreover, the strain could be distinguished from its closely related type strains by phenotypic properties. Based on genotypic and phenotypic evidence, it can be concluded that strain Pm04-4T is a representative of a new Actinoplanes species for which the name Actinoplanes pyxinae sp. nov. is proposed. The type strain is Pm04-4T (=TBRC 16207T=NBRC 115836T). The type strain exhibited activity against Staphylococcus aureus ATCC 25923 as well as four yeast strains, namely Candida albicans TISTR 5554, Candida glabrata TISTR 5006, Candida krusei TISTR 5351 and Candida parapsilosis TISTR 5007. It also showed cytotoxicity against Caco-2, MNT-1 and MCF-7 cancer cells.

Abstract
A novel actinobacterium, designated strain SMC 277T, was isolated from the clay soil in paddy field of Chonburi Province, Thailand, and characterized using polyphasic taxonomy. Strain SMC 277T formed straight chains of nonmotile cylindrical spores with smooth surface developed on aerial mycelia. The typical chemotaxonomic properties of members of the genus Streptomyces were observed in strain SMC 277T, e.g., cell wall peptidoglycan, whole cell sugars, major menaquinones, cellular fatty acids, and polar lipids. Chemotaxonomic data combined with mycelium and spore morphologies supported the assignment of strain SMC 277T to the genus Streptomyces. The results of comparative analysis of the 16S rRNA gene sequences confirmed that strain SMC 277T represented a member of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SMC 277T shared the highest sequence similarity with Streptomyces bambusae NBRC 110903T (98.8%). Genome sequencing revealed a genome size of 6.55 Mbp and a digital G+C content of 73.4 mol%. In addition to the differences in phenotypic characteristics (morphology and physiology), values of ANI (ANIb and ANIm), AAI and dDDH between strain SMC 277T and its closest relative S. bambusae NBRC 110903T were 81.84, 86.77, 76.91 and 26.1%, respectively. Genome annotation and secondary metabolite gene cluster analysis predicted that SMC 277T contained 35 biosynthetic gene clusters encoding diverse bioactive secondary metabolites. It is in agreement with observed antimicrobial activity against drug-resistant bacteria associated with nosocomial infections (methicillin-resistant Staphylococcus aureus, extended-spectrum β-lactamase producing Klebsiella pneumoniae, and multidrug-resistant Acinetobacter baumannii). On the basis of these genotypic and phenotypic characteristics, strain SMC 277T can be characterized to represent a novel species of the genus Streptomyces, for which the name Streptomyces antimicrobicus is proposed. The type strain is SMC 277T (= TBRC 15568T = NBRC 115422T).

Abstract
A novel actinomycete, strain RY43-2T, belonging to the genus Streptomyces, was isolated from a peat swamp forest soil collected from Rayong Province, Thailand. The strain was characterized by using a polyphasic approach. The cell-wall peptidoglycan contained ll-diaminopimelic. Ribose and glucose were detected in its whole-cell hydrolysates. The strain contained anteiso-C15:0, iso-C14:0 and iso-C16:0 as the predominant fatty acids, and MK-9(H4), MK-9(H6) and MK-9(H8) as the major menaquinones. The phospholipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, three unidentified ninhydrin-positive phospholipids and two unidentified phospholipids. Strain RY43-2T showed the highest 16S rRNA gene similarity to Streptomyces misionensis JCM 4497T (98.9 %) and Streptomyces lichenis LCR6-01T (98.9 %). The draft genome of RY43-2T was 6.7 Mb with 6078 coding sequences with an average G+C content of 70.8 mol%. Genomic analysis revealed that the average nucleotide identity (ANI) values based on blast (ANIb) and MUMmer (ANIm) between strain RY43-2T and S. misionensis JCM 4497T were 80.1 and 86.1%, respectively. The ANIb and ANIm values between strain RY43-2T and S. lichenis LCR6-01T were 77.0 and 85.5%, respectively. The digital DNA-DNA hybridization values were 25.2 and 23.0% in comparison with the draft genomes of S. misionensis JCM 4497T and S. lichenis LCR6-01T, respectively. The results of taxonomic analysis suggested that strain RY43-2T represented a novel species of the genus Streptomyces for which the name Streptomyces macrolidinus sp. nov. is proposed. The type strain is RY43-2T (=TBRC 7286T=NBRC 115640T). Strain RY43-2T exhibited antimicrobial activity against Enterococcus faecium ATCC 51559, Colletotrichum capsici BMGC 106 and Colletotrichum gloeosporioides BMGC 107 with the minimum inhibitory concentration values of 25.0, 12.5, and 6.25 µg ml-1. It also exhibited potent antimalarial activity against Plasmodium falciparum K1 with IC50 of 0.0031 µg ml-1. In addition, it showed cytotoxicity against Vero, KB, MCF-7 and NCI-H187 with IC50 values of 0.0347, 6.15, 3.36 and 0.0352 µg ml-1, respectively.

Abstract
A novel mycelium-forming actinomycete strain, designated A-F 0318T, was isolated from a yellow-ringed grass moth (Amata sperbius) collected from Phitsanulok Province, Thailand. Long chains of non-motile cylindrical spores with a smooth surface developed on aerial mycelia. The polyphasic taxonomic study suggested that strain A-F 0318T belonged to the genus
Glycomyces
. The 16S rRNA gene sequence analysis indicated that strain A-F 0318T was closely related to
Glycomyces harbinensis
LL-DO5139T with 97.94 % sequence similarity. The average nucleotide identity (ANI) based on blast, ANI based on the MUMmer algorithm and average amino acid identity values of strain A-F 0318T with
G. harbinensis
LL-DO5139T were 86.9, 89.1 and 84.24 %, respectively. The digital DNA–DNA hybridization value between A-F 0318T and its closest relative,
G. harbinensis
LL-DO5139T was 33.8 %. The digital G+C content of the genomic DNA was 71.7 mol%. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, xylose, glucose and galactose. The predominant menaquinone was MK-10(H4). The predominant fatty acids were iso-C16 : 0, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 1 G. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, two unknown phosphoglycolipids and one unknown phospholipid. Based on comparative analysis of genotypic, phenotypic and chemotaxonomic data, the novel actinomycete strain A-F 0318T (=TBRC 13612T=NBRC 115417T) represents the type strain of a novel species, for which the name Glycomyces amatae sp. nov. is proposed.

Abstract
Actinomycetes are Gram-positive filamentous bacteria well known for the production of bioactive compounds. Recently, many halophilic habitats have been explored for isolation of actinomycetes that exhibit biotechnological potentials. In this investigation, a saline habitat of Rajasthan, Sambhar Salt Lake (SSL) was selected to study the actinomycetes population and Carboxy Methyl Cellulase (CMCase) production by native isolates. A total of sixteen actinomycete isolates, halotolerant and moderately halophilic, were obtained using culture-dependent methods and characterized morphologically and biochemically. They were identified as members of Streptomyces, Nocardiopsis, Pseudonocardia, Saccharospolyspora, and Microbispora. Streptomyces was the most dominating genus, followed by Nocardiopsis. Agar plate assay was used for screening the isolates for CMCase production. Thirteen were found to produce the enzyme, apparent by hydrolysis observed on media plates. The highest relative activity of 22.04 was shown by isolate SSL 14 identified as Nocardiopsis sp. by 16S rDNA sequencing studies and thus selected for further optimization studies. Maximum enzyme (1.08 ± 0.09 U/ml) was produced using medium containing Carboxy Methyl Cellulose (Carbon source) and yeast extract (nitrogen source) at 12% NaCl and pH 9.0, incubated at 30 °C for 96 h. Maximum CMCase production at high salt concentration and pH suggests that Nocardiopsis SSL 14 can be used for industrial processes that operate under excessive saline and alkaline conditions.

Saccharothrix espanaensis
DSM 44229T (98.6%). The zigzag morphology of the spore chain was observed on the aerial mycelia. meso-Diaminopimelic acid was detected in the peptidoglycan. Whole-cell sugars contained rhamnose, ribose, mannose glucose and galactose. Polar lipids were phosphatidylethanolamine, hydroxyphosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol, unidentified ninhydrin-positive glycolipid, unidentified glycolipid and four unidentified lipids. The menaquinones were MK-9(H8), MK-9(H4), MK-9(H2) and MK-9(H0). The predominant fatty acids were iso-C16 : 0, iso-C15 : 0 and anteiso-C17 : 0. The draft genome of SC076T was 8040245 bp with a G+C content of 72.5 mol%. The results of genomic analysis between strain SC076T and the related type strains showed that the digital DNA–DNA hybridization and average nucleotide identity values among the strains were 23.6-32.8% and 77.7–86.8 %, respectively, which are lower than the thresholds used to distinguish strains from others of the same species. Based on the taxonomic evidence, strain SC076T represents a novel species of the genus
Saccharothrix
for which the name Saccharothrix obliqua sp. nov. is proposed. The type strain is SC076T (=TBRC 14540T=NBRC 115117T).

Abstract
N-Substituted phenyl/cyclohexyl-2-(pyridine-4-carbonyl) hydrazine-1-carbothioamides (2a–r) were synthesized, characterized by spectral and analytical data. The compounds were evaluated for antibacterial activity by the disc diffusion method. Most of the compounds showed activity against Gram-positive bacteria. Compound 2h with 4-Sulfapyrimidine phenyl substitution was found to be the most promising candidate, active against Gram-positive and methicillin-resistant Staphylococcus aureus (MRSA) strains with minimum inhibitory concentration (MIC) of (2–7 μg/mL). From the docking study, we predicted that compounds (2r, 2g, 2h, 2o, 2p and 2e) possess better antibacterial activity by having a good binding affinity with target protein and they could be used as potential drugs as antimicrobials. Amongst all the docked compounds, the compound 2h presented near binding affinity & interaction docking score with DNA gyrase enzymes with reference to ciprofloxacin.

Abstract
Two new marine actinobacteria, designated as J2-1T and J2-2T, were isolated from a coral, Favites pentagona, collected from Rayong Province, Thailand. The taxonomic positions of the two strains were identified based on polyphasic taxonomy. Based on morphological characteristics and chemotaxonomy, strains J2-1T and J2-2T were identified as members of the genus Streptomyces and Kineosporia, respectively. Strains J2-1T and J2-2T showed the highest 16S rRNA gene sequence similarity to Streptomyces broussonetiae T44T (98.62 %) and Kineosporia babensis VN05A0415T (98.08 %), respectively. Strain J2-1T had chemotaxonomic properties resembling members of the genus Streptomyces. ll-Diaminopimelic acid, glucose and ribose were detected in the whole-cell hydrolysate. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositolmannoside, unidentified aminolipid and five unidentified phospholipids were detected as the polar lipids. The major cellular fatty acids were C16 : 0 iso, C15 : 0 anteiso, C15 : 0 iso, C16 : 0, C17 : 0 anteiso, C14 : 0 iso and C17 : 0 iso. Strain J2-2T a showed similar cell composition to members of the genus Kineosporia. Both isomers of ll- and meso-diaminopimelic acid were detected in the peptidoglycan. Arabinose, galactose, madurose and xylose were observed in the whole-cell hydrolysate. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, phosphatidylcholine, an unidentified phospholipid and an unidentified glycolipid. The major cellular fatty acids were C16 : 0, C18 : 1 ω9c, C18 : 0 10-methyl, tuberculostearic acid, C18 : 0 and C17 : 0. Both strains could be distinguished from their closely related type strains according to their phenotypic characteristics. Comparative genome analysis indicated the delineation of two novel species based on digital DNA-DNA hybridization and average nucleotide identity values, which were below 70 and 95 %, respectively. The names proposed are Streptomyces corallincola sp. nov. (J2-1T=TBRC 13503T=NBRC 115066T) and Kineosporia corallincola sp. nov. (J2-2T=TBRC 13504T=NBRC 114885T).

Abstract
A novel actinomycete, designated strain ASG 168T, was isolated from cave rock collected from Stegodon Sea Cave in Thailand. Long chains of non-motile spores that were oval or spherical in shape with a smooth surface developed on aerial mycelia. Substrate mycelia fragmented into irregular rod-shaped elements. A polyphasic taxonomic study showed that strain ASG 168T had typical characteristics of members of the genus Prauserella. 16S rRNA gene sequence analysis indicated that strain ASG 168T shared 97.5 % similarity with Prauserella marina MS498T and 96.7 % with Prauserella coralliicola SCSIO 11529T. Average nucleotide identity values with P. coralliicola SCSIO 11529T and P. marina MS498T were 82.98 and 76.08 %, respectively. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, arabinose and galactose. The predominant menaquinone was MK-9(H4). The predominant fatty acids were iso-C16 : 0, C16 : 0 and summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c). The phospholipid profile consisted of phosphatidylethanolamine, phosphatidylmethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and two unknown phospholipids. The G+C content of the genomic DNA was 70.6 mol%. Differentiation of strain ASG 168T from closely related species was evident from digital DNA-DNA hybridization values of 29.2 and 21.3 % with P. coralliicola and P. marina, respectively. Based on comparative analysis of phenotypic, chemotaxonomic and genotypic data, the novel actinomycete strain ASG 168T (=TBRC 13679T=NBRC 114887T) is proposed to be the type strain of a novel species, Prauserella cavernicola sp. nov.

Abstract
Endophytic actinobacterial strain 3R004T was isolated from a root of Justicia subcoriacea collected in Thailand. In this report, the taxonomic position of this strain is described using a polyphasic approach. Based on the morphological characteristics and chemical composition of its cells, strain 3R004T was identified as a member of the genus Streptomyces. It produced a long chain of cylindrical spores on aerial mycelia. ll-Diaminopimelic acid was detected in the cell wall peptidoglycan. The menaquinones were MK-9(H4), MK-9(H6) and MK-9(H8). C16 : 0, iso-C16 : 0, anteiso-C15 : 0 and iso-C15 : 0 were detected as the major cellular fatty acids. Polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and one unidentified lipid. Strain 3R004T showed the highest 16S rRNA gene similarity of 99.45 % to Streptomyces cyaneochromogenes MK-45T. The phylogenomic results indicated that strain 3R004T was close to Streptomyces aquilus GGCR-6T and Streptomyces antibioticus DSM 40234T. The DNA-DNA hybridization and average nucleotide identity values among strain 3R004T and closely related Streptomyces species were 35.5-63.1 % and 82.7-94.3 %, respectively. The type strain produced actinomycin D antibiotic as the major secondary metabolite. The maximum productivity of the actinomycin D (378 mg l-1) was observed when the strain was grown in 301 broth at 30 °C, 180 r.p.m. for 12 days. On the basis of phenotypic and genotypic evidence, strain 3R004T represents a novel species of the genus Streptomyces, for which the name Streptomyces justiciae is proposed. The type strain is 3R004T (=LMG 32138T=TBRC 13128T=NBRC 115065T).

Abstract
Two actinobacteria, designated as strain LDG1-01T and LDG1-06T, were isolated from lichen samples collected in Thailand. Results of morphological characterization, chemotaxonomic studies and 16S rRNA gene analysis indicated that both strains were members of the genus Actinoplanes. MK-9(H4) was found as the major menaquinone. The major fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. Phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol were observed as the polar lipids, but differences in minor unidentified polar lipids were found between the strains. Results of comparative genome analysis based on average nucleotide identity and digital DNA-DNA hybridization calculations revealed that both strains showed values below 95 and 70 %, respectively, from each other and closely related Actinoplanes type strains. Based on data from this polyphasic study, strains LDG1-01T and LDG1-06T represent novel species of the genus Actinoplanes. The names proposed are Actinoplanes lichenicola sp. nov. (type strain, LDG1-01T (=JCM 33066T=TISTR 2982T) and Actinoplanes ovalisporus sp. nov. (type strain, LDG1-06T=JCM 33067T=TISTR 2983T).

Abstract
A novel member of the actinobacteria, designated strain A-T 0013T, was isolated from humic soil on a bird's nest fern (Asplenium nidus L.) collected from Khao Yai National Park in Thailand. According the results of a polyphasic taxonomic study, A-T 0013T had characteristics typical of members of the genus Gordonia. The 16S rRNA gene sequence indicated that A-T 0013T shared ≤98 % sequence similarity with all members of the genus Gordonia. The most closely related species was Gordonia effusa IFM 10200T (97.92 % sequence similarity). The average nucleotide identity based on blast (ANIb) value with G. effusa IFM 10200T was 76.81 %. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, arabinose and galactose. The predominant menaquinone was MK-9(H2). The predominant fatty acids were C16 : 0, C18 : 1ω9c, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), and C18 : 0 10-methyl. Mycolic acid was present. The polar lipid profile for this strain ncluded diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannosides. The G+C content of the genomic DNA was 66.1 mol%. Differentiation of A-T 0013T from the most closely related species, Gordonia effusa IFM 10200T, was evident from digital DNA-DNA hybridization values of 21.8 %. On the basis of the results of comparative analysis of phenotypic, chemotaxonomic and genotypic data, strain A-T 0013T is concluded to represent a novel species of the genus Gordonia, for which the name Gordonia asplenii sp. nov. is proposed. The type strain is A-T 0013T (=TBRC 11910T=NBRC 114549T).

Abstract
A novel actinomycete, strain SMC 257T, was isolated from a soil sample collected from mountain forest, Nan Province, Thailand. Strain SMC 257T formed tightly closed spiral spore chains on aerial mycelia. A polyphasic approach was used for the taxonomic study of this strain. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SMC 257T belonged to the genus Nonomuraea, and the closest phylogenetically related species were Nonomuraea roseoviolacea subsp. carminata JCM 9946T (98.9 % 16S rRNA gene sequence similarity), Nonomuraea rhodomycinica TBRC 6557T (98.4 %), and Nonomuraea roseoviolacea subsp. roseoviolacea JCM 3145T (98.3 %). Genome sequencing revealed a genome size of 9.76 Mbp and a G+C content of 72.3 mol%. The genome average nucleotide identity (ANI) and the digital DNA-DNA hybridization (dDDH) values that distinguished this novel strain from its closest related species were species boundary of 95-96 % and 70 %, respectively. The cell wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars were glucose, ribose, madurose and mannose. The major menaquinone was MK-9(H4). The polar lipid profile consisted of phosphatidylethanolamine, hydroxyphosphatidylethanolamine, lysophosphatidylethanolamine, diphosphatidylglycerol, N-phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The predominant cellular fatty acids were C17 : 0 10-methyl and iso-C16 : 0. Based on comparative analysis of phenotypic, chemotaxonomic and genotypic data, strain SMC 257T is considered to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea montanisoli is proposed. The type strain is SMC 257T (=TBRC 13065T=NBRC 114772T).

Abstract
A novel actinomycete strain CYP1-5T was isolated from the mountain soil sample collected from Chaiyaphum province, Thailand and its taxonomic position was clarified by using a polyphasic taxonomic approach. The chemotaxonomic properties of strain CYP1-5T were consistent within the genus Actinomadura. Cell-wall peptidoglycan of this strain contained meso-diaminopimelic acid. Galactose, madurose, and ribose were presented as the diagnostic sugars in whole-cell hydrolysates. The major menaquinone was MK-9(H6). Major cellular fatty acids were iso-C16:0 and C16:0. Phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, and phosphatidylinositol mannoside were observed as predominant phospholipids. Based on the results of phylogenetic analyses of 16S rRNA gene sequence, strain CYP1-5T was constituent with the genus Actinomadura and was closely related to Actinomadura syzygii GKU157T (99.5%) and Actinomadura chibensis IFM 10266T (= JCM 14158T) (98.2%). The draft genome size of strain CYP1-5T was 9.30 Mb with 72.2 mol% of G + C content. Strain CYP1-5T showed ANIb values of 94.9% with A. syzygii GKU157T and 93.2% with A. chibensis JCM 14158T. Phenotypic characteristics, phylogenetic analysis and genome data support that strain CYP1-5T could be discriminated from its closest relatives, representing a novel species of the genus Actinomadura, for which the name Actinomadura decatromicini sp. nov. is proposed. The type strain is CYP1-5T (= JCM 16996T = KCTC 19916T = TISTR 2901T).

Abstract
A novel actinomycete strain ET3-3T isolated from soil collected from Chachoengsao province, Thailand was taxonomic evaluated using a polyphasic approach. Chemotaxonomic analysis indicated that meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Mycolic acids were present. Ribose, arabinose, and galactose were detected in its whole-cell hydrolysates. The strain comprised C16:0 and TBSA 10-methyl C18:0 as the main fatty acids and MK-8(H4ω-cycl) as the predominant menaquinone. Major polar lipids were phosphatidylinositol, phosphatidylinositol mannoside, phosphatidylethanolamine, and diphosphatidylglycerol. The results of 16S rRNA gene sequence analysis showed that strain ET3-3T was closely related to Nocardia seriolae JCM 30082T (99.2%), Nocardia yunnanensis JCM 30082T (98.4%), and Nocardia concava JCM 12351T (98.2%). The draft genome of ET3-3T was 9.31 Mb with 8826 coding sequences with an average G + C content of 68.0%. The comparison of the draft genome of strain ET3-3T and N. seriolae NBRC 15557T showed the ANIb, ANIm and the digital DNA-DNA hybridization values of 86.3%, 88.5% and 32.9%, respectively. The results of the taxonomic analysis suggested that strain ET3-3T represented a novel species of the genus Nocardia for which the name Nocardia terrae sp. nov. is proposed. The type strain is ET3-3T (= JCM 33776T = TISTR 2837T).

Abstract
A novel actinobacterial strain (TRM 68085T) was isolated from soil ofPopulus euphraticawetland. A polyphasic approach was used to study the taxonomy of TRM 68085Tand the results showed a range of phylogenetic and chemotaxonomic properties consistent with those of the genusStreptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TRM 68085Tshowed the highest similarity value toStreptomyces capitiformicae1H-SSA4T(98.6 %), and phylogenetically clustered withStreptomyces kanasensisZX01T(97.5 %) andStreptomyces ipomoeaeNBRC 13050T(97.4 %).

Abstract
In this study, we tested the ability of Streptomyces to use for their growth benzene, toluene, ethylbenzene, and o-, m-, p-xylenes as sole source of carbon and energy. These bacteria were isolated from agricultural soils and activated sludge samples from a wastewater treatment plant. The results show that Streptomyces are capable of degrading at least one of the BTEX compounds. Among them, 3 isolates from activated sludge called (U, F and V) and a single isolate (SA13) isolated from an agricultural soil, can use as the sole source of carbon and energy, all of these BTEX compounds at concentrations of 1500 mg/L. Based on the analysis of the 16S rRNA gene sequence, two active strains were identified as Streptomyces fimicarius, Streptomyces cavourensis, Streptomyces flavogriseus and Streptomyces pratensis. These strains can be excellent candidates for the bioremediation of the telluric and aquatic sites polluted by these xenobiotics.

Abstract
An endophytic actinomycete, strain 3MP-10T, isolated from the root of Mimosa pudica was taxonomically studied based upon polyphasic approaches. This strain formed spiral spore chains on aerial mycelia. ll-Diaminopimelic acid, glucose and ribose were found in the whole-cell hydrolysates. It belonged to the genus
Streptomyces
and was closely related to
Streptomyces zhaozhouensis
DSM 42101T (98.9 %) and
Streptomyces sedi
JCM 16909T (98.6 %) based on 16S rRNA gene sequence analysis results. The major menaquinones were MK-10(H8), MK-10(H6) and MK-9(H8). The predominant cellular fatty acids were iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The detected phospholipids were diphosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol, phosphatidylethanolamine and phosphatidylglycerol. Strain 3MP-10T had a genome size of 7.2 Mb with a genome G+C content of 73.4 mol%. Results of in silico genome-based similarity analysis revealed ANIb values of 84.94 and 84.77 %, ANIm values of 88.01 and 87.92 %, and dDDH values of 29.9 and 29.6 % when compared with
S. zhaozhouensis
DSM 42101T and
S. sedi
JCM 16909T, respectively. Based on the polyphasic approach, digital DNA–DNA relatedness and average nucleotide identity, we propose that the novel actinomycete represents a novel species, Streptomyces mimosae, with type strain 3MP-10T (=JCM 33328T=TISTR 2646T).

Abstract
Plant associated endophytic actinobacteria may contribute to plant growth and defense by direct or indirect methods. Our aim was to evaluate the plant growth promoting and antifungal activities of endophytic actinobacteria associated with Camellia spp. and related genera, Eurya to find potent plant growth promoting strains that could be applied in future microbe based bioformulations. We isolated 46 endophytic actinobacteria based on morphological characteristics of the isolates. 16S rRNA gene sequence analysis showed that the strains represented nine actinobacterial genera, Nocardia, Amycolatopsis, Streptomyces, Pseudonocardia, Kribbella, Actinomadura, Microbispora, Rothia and Saccharomonospora. In vitro functional characterization of the isolates for plant growth promoting (PGP) traits revealed many potent PGP isolates such as, SA1 and S43 which showed all the tested PGP traits, i.e., phosphate solubilization, indole-3-acetic acid (IAA), ammonia, siderophore and chitinase production. Out of the 46 endophytic actinobacteria isolates, 21 showed inhibition against atleast one test fungal phytopathogen and, isolates SA25 and SA29 exhibited broad spectrum antifungal activity against all the tested phytopathogens. Most of the endophytic actinobacteria isolates having antifungal activity were positive for the presence of chitinase, NRPS (Non-ribosomal peptides synthetase) or PKS-1 (Polyketide Synthase) gene, suggesting the presence of distinctive mechanisms to inhibit the growth of pathogenic plant fungi. ARDRA (Amplified Ribosomal DNA Restriction analysis) and BOX-PCR fingerprinting analysis of the potent isolates with antagonistic activity grouped the isolates into 5 and 4 separate clusters, respectively. In addition, an assessment using bonitur scale revealed the top ranked isolates based on their PGP and biocontrol traits. Further detection of IAA production by the top ranked actinobacterial isolates namely, SA1, T1LA3 and S85 by using thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) was done. Endophytic actinobacteria isolates, namely, SA1, T1LA3, and SA14 were further tested for their efficacy in promoting the growth of commercial tea clones, namely, TV1, TV9, TV18, and TV22 in nursery conditions. All the endophytic isolates tested showed significant differences (P ≤ 0.05) in terms of plant growth promoting parameters in the treated plants compared to untreated control and may, thus be, deemed as potential candidates for application in bioformulations for tea growth.

Abstract
A novel zoosporic actinomycete, designated strain A-T 5661T, was isolated from plant litter collected in Thailand. Strain A-T 5661T developed large multilocular sporangia containing motile sporangiospores at the ends of sporangiophores on substrate mycelium. The results of our polyphasic taxonomic study demonstrated that the strain had characteristics typical of members of the genus Cryptosporangium. The 16S rRNA gene sequence and phylogenetic analyses indicated that strain A-T 5661T shared the sequence similarity ≤98.5 % with all members of the genus Cryptosporangium. The values of DNA-DNA relatedness that distinguished this novel strain from its closest related species were below 70 %. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars were acofriose, arabinose, galactose, glucose, mannose, xylose and ribose. The predominant menaquinones were MK-9(H8) and MK-9(H6) with minor amounts of MK-9(H4) and MK-9(H2). The predominant fatty acids were iso-C16 : 0, C18 : 1ω9c and anteiso-C17 : 0. The polar lipid profile consisted of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and unidentified polar lipids. The G+C content of the genomic DNA was 71.6 mol%. Based on comparative analysis of phenotypic, chemotaxonomic and genotypic data, the novel zoosporic actinomycete A-T 5661T (=TBRC 8127T=NBRC 113237T) is proposed to be the type strain of a novel species, Cryptosporangium phraense sp. nov.

Abstract
Nanoparticles (NPs) are gaining special interest due to their recent applications as antimicrobial agents to defeat the massive threat of resistant pathogens. This study focused on the utilisation of Streptomyces isolate S12 purified from waste discharge soil in the biological synthesis of silver (Ag), selenium (Se), and zinc oxide (ZnO) NPs. The isolate S12 was related to Streptomyces enissocaesilis according to 16S rRNA sequence analysis, morphological characteristics, and biochemical reactions. The cell-free supernatant has been used for the synthesis of Ag, Se, and ZnO NPs. The synthesised NPs were characterised using ultraviolet-visible spectroscopy, dynamic light scattering (DLS), transmission electron microscopy, and Fourier transform infrared spectroscopy. The biogenic NPs were evaluated for antimicrobial effects against different Gram-positive and Gram-negative resistant isolates using the broth microdilution method. They showed antibacterial effect against standard and resistant isolates; Bacillus cereus, Staphylococcus aureus ATCC 29213, S. aureus S1.1, methicillin resistant S. aureus (MRSA 303, 402 and 807), Escherichia coli ATCC 12435, E. coli E7, Klebsiella pneumoniae ATCC 51503, K. pneumoniae K5, K112, Pseudomonas aeruginosa PAO1, and P. aeruginosa P8. This study showed the green synthesis of various NPs using Streptomyces isolate S12 which demonstrated diverse activities against multi-drug resistant isolates.

Abstract
A novel actinomycete, strain PA1-10T, isolated from the leaf of Phyllanthus amarus collected from Bangkok, Thailand, was characterized taxonomically using a polyphasic approach. This strain contained the characteristics consistent with those of members of the genus Nonomuraea. It formed short rugose spore chain on aerial mycelium. The diamino acid in cell wall peptidoglycan was meso-diaminopimelic acid. Galactose, glucose, madurose, mannose, and ribose were found in whole-cell hydrolysates. Predominant menaquinones were MK-9 (H2), MK-9 (H4), and MK-9 (H6). Major cellular fatty acids were iso-C16:0 and C17:0 10-methyl. Phospholipid profiles were composed of phosphatidylinositol mannoside (PIM), lyso-phosphatidylethanolamine (lyso-PE), phosphatidylethanolamine (PE), methylphosphatidylethanolamine (PME), diphosphatidylglycerol (DPG), and phosphatidylglycerol (PG). The G + C content of DNA was 71.2 mol%. Strain PA1-10T showed the highest 16S rRNA gene sequence similarity with Nonomuraea candida JCM 15928T (98.35%) and shared the same node with Nonomuraea maritima JCM 18321T in the phylogenetic tree analysis. Based on the phenotypic characteristics, DNA-DNA relatedness, and average nucleotide identity (ANI), the strain is considered to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea phyllanthi is proposed. The type strain is PA1-10T (= JCM 33073T = NBRC 112774T = TISTR 2497T).

Abstract
A novel actinomycete, designated strain XZ 46T, was isolated from acid sandy soil collected from the Tibetan Plateau, China. Its taxonomic position was determined using a polyphasic approach. Strain XZ 46T shows the typical morphological and chemotaxonomic features of members of the genus Streptomyces: slightly yellow to brown substrate mycelia and grayish white to slightly yellow aerial hyphae forming cylindrical and spiny spores; meso-diaminopimelic acid in the cell wall peptidoglycan; MK-9(H8), MK-9(H4) and MK-9(H2) as predominant menaquinones; diphosphatidylglycerol, phospatidylethanolamine, phosphatidylglycerol and phosphatidylinositol as main polar lipids; and iso-C15:0, iso-C16:0 and anteiso-C15:0 as major cellular fatty acids. The G+C content of the draft genome sequence, consisting of 8,995,813 bp, is 71.23%. The16S rRNA gene sequence analysis indicated that strain XZ 46T shows high sequence similarity to Streptomyces luteogriseus NBRC 13402T as well as forming an independent lineage clade with it in phylogenetic trees. Multilocus sequence analysis (MLSA) of five housekeeping genes (atpD, gyrB, recA, rpoB and trpB) illustrated that Streptomyces hawaiiensis is also a very closely related taxon. However, DNA-DNA hybridization, MLSA evolutionary distance and phenotypic properties demonstrate that strain XZ 46T can be distinguished from these phylogenetically related Streptomyces species. Therefore, it is concluded that strain XZ 46T represents a novel species of the genus Streptomyces, for which the name Streptomyces tibetensis is sp. nov. proposed. The type strain is XZ 46T (= CGMCC 4.7579T = KCTC 49221T).

Abstract
A novel actinomycete, designated strain NX62T, was isolated from desert soil obtained from Isolaginsha, Ningxia Hui Autonomous Region, China. Its taxonomic position was determined using a polyphasic approach. The strain shows the typical morphological and chemotaxonomic features of members of the genus Lentzea: slight to dark yellow substrate mycelia and white to greyish white aerial hyphae fragmenting into rod-shaped elements; meso-diaminopimelic acid in the cell wall peptidoglycan; MK-9(H4) and MK-9(H2) as menaquinones; diphosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine and phosphatidylinositol as main polar lipids; iso-C16:0 and iso-C17:0 as major cellular fatty acids; and DNA G+C content of 70.1 mol%. 16S rRNA gene sequence analysis indicated that strain NX62T shows high similarity to Lentzea cavernae SYSU K10001T (99.3%) and Lentzea albida IFO 16102T (98.9%), and formed a monophyletic clade with L. cavernae SYSU K10001T in the phylogenetic tree. Based on a comparison of the phenotypic properties and the low level of DNA-DNA relatedness, strain NX62T can be distinguished from phylogenetically related Lentzea species. Therefore, it is concluded that strain NX62T represents a novel species of the genus Lentzea, for which the name Lentzea isolaginshaensis sp. nov. is proposed. The type strain is NX62T (= CGMCC 4.7522T = KCTC 49179T).

Streptomyces spp. From Ethiopia Producing Antimicrobial Compounds: Characterization via Bioassays, Genome Analyses, and Mass Spectrometry. Front Microbiol 2018; 9:1270. [PMID: 29946312 PMCID: PMC6007079 DOI: 10.3389/fmicb.2018.01270] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2018] [Accepted: 05/24/2018] [Indexed: 11/13/2022] Open
Abstract
A total of 416 actinomycete cultures were isolated from various unique environments in Ethiopia and tested for bioactivity. Six isolates with pronounced antimicrobial activity were chosen for taxonomic identification and further investigation. Morphological and cultural properties of the isolates were found to be consistent with those of the genus Streptomyces, which was further confirmed by phylogenetic analysis based on 16S rRNA gene sequences. One of the isolates, designated Streptomyces sp. Go-475, which displayed potent activity against both pathogenic yeasts and Gram-positive bacteria, was chosen for further investigation. Metabolite profiles and bioactivity of Go-475 incubated on wheat bran-based solid and soya flour-based liquid media were compared using high-resolution LC-MS. This allowed identification of several known compounds, and suggested the ability of Go-475 to produce new secondary metabolites. Major anti-bacterial compounds were purified from liquid cultures of Go-475, and their structures elucidated by NMR and HRMS as 8-O-methyltetrangomycin and 8-O-methyltetrangulol. In addition, many potentially novel metabolites were detected, the majority of which were produced in solid media-based fermentation. The genome sequence of Streptomyces sp. Go-475 was obtained using a hybrid assembly approach of high quality Illumina short read and low quality Oxford Nanopore long read data. The complete linear chromosome of 8,570,609 bp, featuring a G+C content of 71.96%, contains 7,571 predicted coding sequences, 83 t(m)RNA genes, and six rrn operons. Analysis of the genome for secondary metabolite biosynthesis gene clusters further confirmed potential of this isolate to synthesize chemically diverse natural products, and allowed to connect certain clusters with experimentally confirmed molecules.

Abstract
A novel endophytic actinomycete, strain WPS1-2T, isolated from a root of Globba winitii C. H. Wright, was characterized taxonomically by using a polyphasic approach. Strain WPS1-2T exhibited identical characteristics to the members of the genus Micromonospora. Single spores were observed directly on substrate mycelia. The cell-wall peptidoglycan of the strain contained meso-diaminopimelic acid and 3-OH-meso-diaminopimelic acid. Whole-cell hydrolysates contained glucose, ribose, arabinose and xylose. The predominant menaquinones were MK-10(H8) and MK-10(H10). The major cellular fatty acids consisted of iso-C15 : 0, iso-C16 : 0 and anteiso-C15 : 0. According to the 16S rRNA gene sequence of the strain, WPS1-2T showed highest similarity to Micromonospora costi CS1-12T (99.02 %). Phylogenetic analysis of the gyrase subunit B (gyrB) gene indicated that the strain was related to M. costi CS1-12T. The DNA G+C content was 73.7 mol%. The strain could be distinguished from closely related type strains by using a combination of morphological, chemotaxonomic, physiological and biochemical data together with DNA-DNA relatedness values. Based on these observations, strain WPS1-2T is considered to represent a novel species of the genus Micromonospora, for which the name Micromonospora globbae sp. nov. is proposed. The type strain is WPS1-2T (=KCTC 39787T=NBRC 112325T=TISTR 2405T).

Abstract
An attempt was made to identify actinobacterial strains present in the marine soil of East Coast regions viz., Chirala, Bapatla, and Peddaganjam, Andhra Pradesh; Kanyakumari, Tamil Nadu and Goa, Goa along with the study of their antimicrobial potential. Eight out of 73 actinobacterial strains isolated from these regions showed strong antimicrobial activity against Gram positive bacteria, Gram negative bacteria, and Candida albicans. Molecular identification (16S rRNA analysis) of the eight strains revealed that they belong to Dietzia sp., Kocuria sp., Nocardiopsis sp., and Streptomyces spp. ISP (International Streptomyces project) -1, ISP-2 and starch casein media supported high antimicrobial potential after 5-6 days of growth. Production of antimicrobials by the strains varied significantly with different carbon and nitrogen sources. Gas chromatography mass spectrometry (GCMS) analysis of volatile compounds produced by the strains illustrated an array of antimicrobial compounds such as 1, 2-benzene dicarboxylic acid, 2-piperidinone, pyrrolo[1,2-a]pyrazine-1,4-dion, phenyl ethyl alcohol, 3-phenyl propionic acid etc. Ours is the first report on the study and detection of above mentioned antimicrobial metabolites from Dietzia sp. (A3), Kocuria sp. (A5), and Nocardiopsis sp. (A7). By sequence based analysis for secondary metabolites, non-ribosomal peptide synthetase (NRPS) gene cluster was noticed in six strains (A2, A3, A4, A6, A7, and A8) and none of them had polyketide synthase (PKS) system. The present study intimates the biological potentiality of the actinobacterial strains isolated from East Coast of Andhra Pradesh, India which reveals further scope to investigate new bioactive compounds from them by employing both natural product chemistry and modern biotechnological aspects.

Abstract
A novel actinomycete, designated strain KC-035T, was isolated from soil collected from Krung Ching Waterfall National Park, Nakhon Si Thammarat Province, Thailand. Its taxonomic position was determined using a polyphasic approach. The strain had morphological and chemotaxonomic properties typical of members of the genus Streptomyces: flexuous spore chain; ll-diaminopimelic acid in the cell-wall peptidoglycan; MK-9(H8), MK-9(H6) and MK-9(H4) as menaquinones; diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside as phospholipids; anteiso-C15 : 0, C16 : 0, iso-C16 : 0, iso-C15 : 0 and iso-C14 : 0 as major cellular fatty acids; and DNA G+C content of 72 mol%. 16S rRNA gene sequence analysis revealed that strain KC-035T showed high similarity to Streptomyces albiflavescens n20T (99.16 %) and Streptomyces siamensis KC-038T (98.43 %) as well as formed a monophyletic clade with them in the phylogenetic tree. On the basis of comparison of phenotypic properties and the low level of DNA-DNA relatedness, strain KC-035T could be distinguished from its closely related Streptomyces species and is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces krungchingensis sp. nov. is proposed. The type strain is KC-035T (=NBRC 110087T=KCTC 29503T=TISTR 2402T).

Abstract
A potent actinobacterial strain isolated from the marine samples of Bheemunipatnam beach, Visakhapatnam, India, was identified as Rhodococcus sp. VLD-10 using the conventional and genomic (16S rRNA) approaches. Bioactive compounds responsible for the antimicrobial activity of the strain were elucidated by cultivating the strain VLD-10 in a modified yeast extract-malt extract-lactose broth followed by subsequent chromatographic and spectroscopic analyses. Extraction, purification, and structural confirmation of five compounds, viz., benzoic acid, 2-nitrobenzaldehyde, 4-chlorobenzaldehyde, nonadeconoic acid, and 3-isopropylhexahydro-1H-pyrido[1,2-a] pyrazine-1,4(6H)-dione, from Rhodococcus sp. VLD-10 were fruitfully described. The bioactivity of the compounds isolated from the strain VLD-10 against Gram-positive as well as Gram-negative bacteria, yeast, and molds was tested and their minimum inhibition concentration was reported. Antibacterial activity of 3-isopropylhexahydro-1H-pyrido[1,2-a] pyrazine-1,4(6H)-dione is more prominent against Bacillus subtilis, B. cereus, B. megaterium, Corynebacterium diphtheriae, and Escherichia coli, whereas its antifungal spectrum showed less potency against yeast and fungi. This is the first report on the natural occurrence and bioactivity of 3-isopropylhexahydro-1H-pyrido[1,2-a] pyrazine-1,4(6H)-dione from Rhodococcus sp. VLD-10.

Abstract
A novel actinomycete strain, designated Js-1T, was isolated from Tremella fuciformis collected from Gutian, Fujian Province, in southeastern China. The taxonomic status of this strain was determined by a polyphasic approach, which demonstrated that the novel strain was a member of the genus Streptomyces. The cell walls of this strain were found to contain ll-diaminopimelic acid, muramic acid and glycine. An analysis of whole-cell hydrolysates revealed that no characteristic sugar was present. The key identified menaquinones were MK-9 (H6) and MK-9 (H8), while the diagnostic polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylmethylethanolamine and phosphatidylglycerol. The main cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, C16 : 0 and iso-C16 : 0. An analysis of an almost complete 16S rRNA gene sequence showed that the strain shared the highest levels of sequence similarity with Streptomyces sannanensisKC-7038T (97.87 %), Streptomyces hebeiensis YIM 001T (97.84 %), Streptomyces pathocidini NBRC 13812T (97.80 %), Streptomyces cocklensis BK168T (97.25 %), Streptomyces coerulescens NBRC 12758T (97.12 %), Streptomyces aurantiogriseus NBRC 12842T (97.06 %) and Streptomyces rimosussubsp. rimosus ATCC 10970T (97.04 %). The DNA G+C content of the genomic DNA of strain Js-1T was 70.1 mol%. Furthermore, DNA-DNA hybridization tests revealed that the relatedness values between strain Js-1T and the most closely related species ranged from 15.10 to 47.20 %. Based on its phenotypic and genotypic characteristics, strain Js-1T (=CCTCC M 2011365T=JCM 30846T) is considered to represent a novel species within the genus Streptomyces, which we classified as Streptomycestremellae sp. nov.

Abstract
Aphids are major insect pests for crops, causing damage by direct feeding and transmission of plant diseases. This paper was completed to discover and characterize a novel insecticidal metabolite against aphids from soil actinobacteria. An insecticidal activity assay was used to screen 180 bacterial strains from soil samples against mustard aphid, Lipaphis erysimi. The bacterial strain H008 showed the strongest activity, and it was identified by the phylogenetic analysis of the 16S rRNA gene and physiological traits as a novel species of genus Streptomyces (named S. laindensis H008). With the bioassay-guided method, the insecticidal extract from S. laindensis H008 was subjected to chromatographic separations. Finally, a novel insecticidal peptide was purified from Streptomyces laindensis H008 against L. erysimi, and it was determined to be S-E-P-A-Q-I-V-I-V-D-G-V-D-Y-W by TOF-MS and amino acid analysis.
