Deng Y, Jiang ZM, Han XF, Su J, Yu LY, Liu WH, Zhang YQ. Pangenome analysis of the genus Herbiconiux and proposal of four new species associated with Chinese medicinal plants. Front Microbiol 2023; 14:1119226. [PMID: 36925467 PMCID: PMC10011130 DOI: 10.3389/fmicb.2023.1119226] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 02/10/2023] [Indexed: 03/04/2023] Open
Abstract
Five Gram-stain-positive, aerobic, non-motile actinobacterial strains designated as CPCC 205763T, CPCC 203386T, CPCC 205716T, CPCC 203406T, and CPCC 203407 were obtained from different ecosystems associated with four kinds of Chinese traditional medicinal plants. The 16S rRNA gene sequences of these five strains showed closely related to members of the genus Herbiconiux of the family Microbacteriaceae, with the highest similarities of 97.4-99.7% to the four validly named species of Herbiconiux. In the phylogenetic trees based on 16S rRNA gene sequences and the core genome, these isolates clustered into the clade of the genus Herbiconiux within the lineage of the family Microbacteriaceae. The overall genome relatedness indexes (values of ANI and dDDH) and the phenotypic properties (morphological, physiological and chemotaxonomic characteristics) of these isolates, readily supported to affiliate them to the genus Herbiconiux, representing four novel species, with the isolates CPCC 203406T and CPCC 203407 being classified in the same species. For which the names Herbiconiux aconitum sp. nov. (type strain CPCC 205763T = I19A-01430T = CGMCC 1.60067T), Herbiconiux daphne sp. nov. (type strain CPCC 203386T = I10A-01569T = DSM 24546T = KCTC 19839T), Herbiconiux gentiana sp. nov. (type strain CPCC 205716T = I21A-01427T = CGMCC 1.60064T), and Herbiconiux oxytropis sp. nov. (type strain CPCC 203406T = I10A-02268T = DSM 24549T = KCTC 19840T) were proposed, respectively. In the genomes of these five strains, the putative encoding genes for amidase, endoglucanase, phosphatase, and superoxidative dismutase were retrieved, which were classified as biosynthetic genes/gene-clusters regarding plant growth-promotion (PGP) functions. The positive results from IAA-producing, cellulose-degrading and anti-oxidation experiments further approved their potential PGP bio-functions. Pangenome analysis of the genus Herbiconiux supported the polyphasic taxonomy results and confirmed their bio-function potential.

Properties of Modestobacter deserti sp. nov., a Kind of Novel Phosphate-Solubilizing Actinobacteria Inhabited in the Desert Biological Soil Crusts. Front Microbiol 2021; 12:742798. [PMID: 34803963 PMCID: PMC8602919 DOI: 10.3389/fmicb.2021.742798] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 10/05/2021] [Indexed: 11/29/2022] Open
Abstract
Three Gram-stain-positive, aerobic, motile actinobacterial strains designated as CPCC 205119T, CPCC 205215, and CPCC 205251 were isolated from different biological soil crust samples collected from Tengger Desert, China. The 16S rRNA gene sequence comparison of these three strains showed they had almost identical 16S rRNA genes, which were closely related to members of the family Geodermatophilaceae, with the highest similarities of 96.3–97.3% to the species of Modestobacter. In the phylogenetic tree based on 16S rRNA gene sequences, these isolates clustered into a subclade next to the branch containing the species of Modestobacter lapidis and Modestobacter multiseptatus, within the lineage of the genus Modestobacter. The comparative genomic characteristics (values of ANI, dDDH, AAI, and POCP) and the phenotypic properties (morphological, physiological, and chemotaxonomic characteristics) of these isolates readily supported to affiliate them to the genus Modestobacter as a single separate species. For which, we proposed that the isolates CPCC 205119T, CPCC 205215, and CPCC 205251 represent a novel species of the genus Modestobacter as Modestobacter deserti sp. nov. CPCC 205119T (=I12A-02624=NBRC 113528T=KCTC 49201T) is the type strain. The genome of strain CPCC 205119T consisted of one chromosome (4,843,235bp) containing 4,424 coding genes, 48 tRNA genes, five rRNA genes, three other ncRNA genes, and 101 pseudogenes, with G+C content of 74.7%. The whole-genome sequences analysis indicated that this species contained alkaline phosphatase genes (phoA/phoD), phosphate transport-related genes (phoU, phnC, phnD, phnE, phoB, phoH, phoP, phoR, pitH, ppk, pstA, pstB, pstC, and pstS), trehalose-phosphate synthase gene (otsA), trehalose 6-phosphate phosphatase gene (otsB) and other encoding genes for the properties that help the microorganisms to adapt to harsh environmental conditions prevalent in deserts. Strains of this species could solubilize tricalcium phosphate [Ca3(PO4)2] and phytin, assimilate pyrophosphate, thiophosphate, dithiophosphate, phosphoenol pyruvate, 2-deoxy-d-glucose-6-phosphate, and cysteamine-S-phosphate.

Abstract
Four undescribed alkaloids, namely collacyclumines A-D, along with a known analogue, agrocybenine, were isolated from the endophytic fungus Colletotrichum salsolae SCSIO 41021 derived from the mangrove plant Kandelia candel (L.) Druce. Collacyclumine A represents the first case of dimeric pyrrolidine alkaloid in nature. The structures of these compounds were elucidated by a combination of NMR spectra, HRESIMS data, and X-ray diffraction experiment. A proposed biosynthetic pathway of these isolated compounds were also discussed. None of compounds showed cytotoxic effects against ten cell lines.

Abstract
The taxonomic position of an actinobacterium, designated CPCC 204279T, which was isolated from a rhizosphere soil sample of the herb Limonium sinense collected from Xinjiang Province, China, was established using a polyphasic approach. Whole-cell hydrolysates of strain CPCC 204279T contained galactose and arabinose as diagnostic sugars and meso-diaminopimelic acid as the diamino acid. The muramic acid residues in the peptidoglycan were N-acetylated. The predominant menaquinone was MK-9(H4). The phospholipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16 : 0, iso-C16 : 0 2-OH, C16 : 1ω9c, iso-C16 : 1 and C16 : 0. The genomic DNA G+C content was 73.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CPCC 204279T should be placed in the family Pseudonocardiaceae, in which the strain formed a distinct lineage next to the genus Actinophytocola. Signature nucleotides in the 16S rRNA gene sequence showed that the strain contained the Pseudonocardiaceae family-specific 16S rRNA signature nucleotides and a genus-specific diagnostic nucleotide signature pattern. The combination of phylogenetic analysis and phenotypic characteristics supported the conclusion that strain CPCC 204279T represents a novel species of a new genus in the family Pseudonocardiaceae, for which the name Herbihabitans rhizosphaerae gen. nov., sp. nov. is proposed. Strain CPCC 204279T (=NBRC 111774T=DSM 101727T) is the type strain of the type species.

Abstract
Bis-naphtho-γ-pyrones (BNPs) are an important group of aromatic polyketides derived from fungi, and asperpyrone-type BNPs are produced primarily by Aspergillus species. The fungal strain Aspergillus niger SCSIO Jcsw6F30, isolated from a marine alga, Sargassum sp., and identified according to its morphological traits and the internal transcribed spacer (ITS) region sequence, was studied for BNPs secondary metabolisms. After HPLC/MS analysis of crude extract of the fermentation broth, 11 asperpyrone-type BNPs were obtained directly and quickly by chromatographic separation in the extract, and those isolated asperpyrone-type BNPs were structurally identified by NMR and MS analyses. All of the BNPs showed weak cytotoxicities against 10 human tumor cells (IC50 > 30 μM). However, three of them, aurasperone F (3), aurasperone C (6) and asperpyrone A (8), exhibited obvious COX-2–inhibitory activities, with the IC50 values being 11.1, 4.2, and 6.4 μM, respectively. This is the first time the COX-2–inhibitory activities of BNPs have been reported.

Abstract
The taxonomic positions of three Gram-stain-positive, aerobic strains, designated YIM 75722, 75726 and 75728T, and isolated from a soil sample collected from Kurnool of Andhra Pradesh province, India, were assessed using a polyphasic approach. Growth was observed at pH 7.0-10.0 (optimum pH 7.0), 15-28 °C (optimum 28 °C) and 0-8 % (w/v) NaCl (grew without NaCl). Strains showed cylindrical spores with straight-chain morphology on aerial mycelium, but did not reveal sporangium-like structures or fragmentation of the substrate mycelium. Whole-cell hydrolysates of all strains contained galactose and ribose as the diagnostic sugars and meso-diaminopimelic acid as the diamino acid. The predominant menaquinone was MK-9(H4); MK-9 (H6) and MK-10 (H4) were present in smaller amounts. The phospholipid pattern consisted mainly of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine. The major fatty acids were i-C15 : 0, ai-C15 : 0, i-C17 : 0 and ai-C17 : 0. The genomic DNA G+C content was 68.0 mol%. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain YIM 75728T should be placed within the family Pseudonocardiaceae, in which the strain formed a distinct lineage. The combination of phylogenetic analysis, phenotypic characteristics and chemotaxonomic data support the conclusion that strain YIM 75728T represents a novel species of a novel genus of the family Pseudonocardiaceae for which the name Actinorectispora indica gen. nov., sp. nov., is proposed. Strain YIM 75728T ( = DSM 45410T = CCTCC AA 209065T) is the type strain of Actinorectispora indica. Strain YIM 75728T was considered as the type strain over the other two strains based on the highest sequence read length of the strain.

Abstract
A novel endophytic actinobacterium, designated strain YIM 690053(T), was isolated from healthy stems of Salsola ferganica Drob, and was characterized using a polyphasic taxonomic approach. The strain formed well-branched substrate mycelia with no fragmentation, and abundant aerial mycelia that differentiated into long spores. The strain was found to grow at 10-55 °C, pH 6.0-10.0 and in the presence of 0-7 % (w/v) NaCl. The genomic DNA G+C content was determined to be 70.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 690053(T) belongs to the genus Marinactinospora, and it shared the highest 16S rRNA gene sequence similarity with Marinactinospora thermotolerans SCSIO 00652(T) (98.96 %). However, the DNA-DNA relatedness values between the two strains was 37.85 ± 2.77 %. Based on the differences in the molecular and biochemical characteristics from its closest relative, strain YIM 690053(T) is concluded to represent a novel species of the genus Marinactinospora, for which the name Marinactinospora endophytica sp. nov. is proposed. The type strain is YIM 690053(T)(=KCTC 29664(T) = DSM 46799(T)).

Abstract
A novel endophytic actinobacterium, designated strain SP28S-3(T), was isolated from a surface-sterilized stem of Tamarix taklamakanensis collected from the southern edge of Taklamakan desert, Xinjiang, China. Strain SP28S-3(T) was found to show chemotaxonomic and morphological properties consistent with its classification in the genus Prauserella. The polar lipids were found to consist of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphoglycolipid, phosphatidylcholine, phosphatidylinositol, a glycolipid, an aminolipid and unidentified phospholipids. The major fatty acids (>10 %) were identified as iso-C16:0 and C16:0. The genomic DNA G+C content was determined to be 69.7 mol%. Phylogenetic analysis of strain SP28S-3(T) clearly showed that the strain had the highest similarity of 16S rRNA gene sequence with Prauserella coralliicola SCSIO 11529(T) (99.9 %), followed by Prauserella marina DSM 45268(T) (97.0 %) and is affiliated with the genus Prauserella. The low level (47.8 ± 5.5 %) of DNA-DNA relatedness between strain SP28S-3(T) and P. coralliicola SCSIO 11529(T) combined with other polyphasic taxonomic evidence clearly support the conclusion that strain SP28S-3(T) represents a novel Prauserella species, for which the name Prauserella endophytica sp. nov. is proposed. The type strain is SP28S-3(T) (=DSM 46655(T) = CGMCC 4.7182 (T)).

Abstract
A novel actinomycete strain, designated VRC21(T), was isolated from the rhizosphere of Callistemon citrinus collected from Hyderabad, India. The morphological and chemotaxonomic properties of strain VRC21(T) was consistent with the characteristics of members of the genus Streptosporangium, that is, the formation of sporangia on aerial mycelium, coiled unbranched hyphae within the spore vesicle, the presence of meso-diaminopimelic acid in the cell wall, and madurose and galactose as major whole-cell sugars. Diagnostic polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol-mannosides. The predominant menaquinones were MK-9(H2) and MK-9(H4). The major cellular fatty acids were iso-C14:0, iso-C16:0, C17:0 10-methyl, C18:1w9c and C18:0 10-methyl. 16S rRNA gene sequence analyses revealed that strain VRC21(T) was a member of the genus Streptosporangium. The highest similarity values were observed with S. carneum DSM 44125(T) (98.2%) and S. fragile DSM 43847(T) (98.2%); the values of the remaining type strains were below 98%. The values of DNA-DNA relatedness between the strain VRC21(T) and the type strains of the related species were below 70%. On the basis of the polyphasic evidence, the strain VRC21(T) should be classified as novel species Streptosporangium terrae sp. nov. in the genus Streptosporangium. The type strain is VRC21(T) (=KCTC 29207(T)=MTCC 11724(T)).

Abstract
A novel actinomycete, designated strain CA15-2T, was isolated from a soil sample collected from the rhizosphere of tamarisk in the Lop Nor region, Xinjiang, China, and was characterized by using a polyphasic taxonomic approach. Optimal growth occurred at 37 °C and pH 7.5–8.0 and with 5 % (w/v) NaCl. Strain CA15-2T formed white to pale-yellow branched substrate mycelium without fragmentation and sparse aerial mycelium with wavelike curves. Whole-cell hydrolysates of the isolate contained meso-diaminopimelic acid as the diagnostic diamino acid of the cell wall but no diagnostic sugars. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylmethylethanolamine, phosphatidylethanolamine, one unidentified glycolipid, one unidentified phospholipid and other unidentified lipids. MK-9(H8), MK-10(H8) and MK-10(H6) were the predominant menaquinones. The major fatty acids were iso-C16 : 0 and C16 : 0. The G+C content of the genomic DNA was 69.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CA15-2T formed a distinct subclade in the family
Nocardiopsaceae
, with less than 95 % 16S rRNA gene sequence similarity to all known members of the family
Nocardiopsaceae
. On the basis of the evidence from our polyphasic study, a novel genus, Allosalinactinospora gen. nov., is proposed, with the type species Allosalinactinospora lopnorensis gen. nov., sp. nov. The type strain of Allosalinactinospora lopnorensis is strain CA15-2T ( = DSM 45697T = CGMCC 4.7074T).

Abstract
An actinomycete strain, designated I12A-02593(T), was isolated from a desert soil crust sample collected in the Shapotou region of Tengger Desert, north-west China. The isolate grew well on International Streptomyces Project (ISP) media 2, 3, 5 and 7, YS and Bennett's agar; it produced spherical bodies and formed clumps on the aerial mycelia on ISP 5 agar plates. Chemotaxonomically, the strain contained meso-diaminopimelic acid as the diagnostic diamino acid, arabinose and galactose as the diagnostic sugars in whole-cell hydrolysates, MK-9(H4) as the sole isoprenoid quinone, and iso-C16 : 0, iso-C16 : 0 2-OH and iso-C16 : 1 H as the major cellular fatty acids, without mycolic acids. The profile of the phospholipids mainly comprised diphosphatidylglycerol, phosphatidylethanolamine and hydroxyphosphatidylethanolamine. The genomic DNA G+C content was 70.1 mol%. The 16S rRNA gene sequence of strain I12A-02593(T) exhibited 96.4-97.4 % similarities with members of the genus Actinophytocola. In the phylogenetic tree based on 16S rRNA gene sequences, the isolate formed a robust cluster with Actinophytocola oryzae NBRC 105245(T), Aactinophytocola timorensis NBRC 105524(T), Actinophytocola corallina NBRC 105525(T), Actinophytocola burenkhanensis NBRC 105883(T)and Actinophytocola xinjiangensis NBRC 106673(T). DNA-DNA hybridization values between strain I12A-02593(T) and the five species of the genus Actinophytocola were all less than 70 %. On the basis of the polyphasic taxonomy evidence, a novel species of the genus Actinophytocola is proposed, with the name Actinophytocola gilvus sp. nov. The type strain is I12A-02593(T) ( = CPCC 203543(T) = DSM 45828(T) = NBRC 109453(T) = KCTC 29165(T)). An emended description of the genus Actinophytocola is also provided.

Abstract
A novel actinomycete strain, designated VRC122T, was isolated from a Callistemon citrinus rhizosphere sample collected from New Delhi, India, and its taxonomic status was determined by using a polyphasic approach. Strain VRC122T was a Gram-stain-positive, aerobic, non-motile, non-acid–alcohol-fast strain. Phylogenetic analysis based on 16S rRNA gene sequences showed the strain was placed in a well-separated sub-branch within the genus
Saccharopolyspora
. The highest levels of 16S rRNA gene sequence similarity were found with
Saccharopolyspora hirsuta subsp. kobensis
JCM 9109T (98.71 %),
Saccharopolyspora antimicrobica
I05-00074T (98.69 %) and
Saccharopolyspora jiangxiensis
W12T (98.66 %); 16S rRNA gene sequence similarities with type strains of all other species of the genus
Saccharopolyspora
were below 98 %. Chemosystematic studies revealed that it contained meso-diaminopimelic acid. Arabinose and galactose were the predominant whole-cell sugars. Diagnostic polar lipids were diphosphatidylglycerol, phosphatidylinositol and phosphatidylcholine. MK-9(H6) was the predominant menaquinone. C14 : 0, C16 : 0, iso-C15 : 0, iso-C16 : 0, iso-C17 : 0, anteiso-C15 : 0, anteiso-C17 : 0, C17 : 0 cyclo and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) were the major cellular fatty acids. The G+C content of the genomic DNA was 69.5 mol%. The results of DNA–DNA hybridization (30 %, 22 % and 25 %, respectively) with type strains of the above-mentioned species, in combination with differences in physiological and biochemical data supported that strain VRC122T represents a novel species of the genus
Saccharopolyspora
, for which the name Saccharopolyspora indica sp. nov., is proposed. The type strain is VRC122T ( = KCTC 29208T = MTCC 11564T = MCC 2206T = ATCC BAA-2551T).

Abstract
A new fungal strain, displaying strong toxic activity against brine shrimp larvae, was isolated from a deep sea sediment sample collected at a depth of 1300 m. The strain, designated as F00120, was identified as a member of the genus Penicillium on the basis of morphology and ITS sequence analysis. One new sesquiterpene quinone, named penicilliumin A (1), along with two known compounds ergosterol (2) and ergosterol peroxide (3), were isolated and purified from the cultures of F00120 by silica gel column, Sephadex LH-20 column, and preparative thin layer chromatography. Their structures were elucidated by detailed nuclear magnetic resonance (NMR) and mass spectroscopic (MS) analysis as well as comparison with literature data. The new compound penicilliumin A inhibited in vitro proliferation of mouse melanoma (B16), human melanoma (A375), and human cervical carcinoma (Hela) cell lines moderately.

Morphological and chemotaxonomic characterization of actinomycete strain S582 isolated from the gut of a termite (Speculitermes sp.) in Pathum Thani Province, Thailand, clearly demonstrated that this strain is a member of the genus Saccharopolyspora. 16S rDNA sequence analysis for the strain supported the assignment of the strain to the genus Saccharopolyspora. The similarity value of sequences between this strain and the closely related species Saccharopolyspora endophytica was 99.5%. The DNA G+C content was 70.2 mol%. DNA-DNA hybridization results (53.3%) and some physiological and biochemical properties indicated that strain S582(T) was distinguished from the phylogenetically closest relatives. Based on these genotypic and phenotypic data, strain S582(T) should be a new species in the genus Saccharopolyspora and the name Saccharopolyspora pathumthaniensis sp. nov. is proposed for the strain. The type strain is S582(T) (=NBRC 104112(T) =BCC 28624(T)).

Abstract
A Gram-positive, aerobic, non-motile actinobacterium, designated strain 6014T, was isolated from a soil sample collected from Qinghai province, north-west China, and subjected to a polyphasic taxonomic study. The isolate formed elementary branching hyphae and abundant aerial mycelia with globose sporangia on ISP 4 and R2A media. Whole-cell hydrolysates of strain 6014T contained arabinose, galactose and ribose as diagnostic sugars and meso-diaminopimelic acid as the diagnostic diamino acid. The polar lipids consisted of phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, N-acetylglucosamine-containing phospholipids, two unknown phospholipids and an unknown glycolipid. The menaquinone system contained MK-9(H2) and MK-9(H4). The major fatty acids were C14 : 0, i-C15 : 0, C16 : 0 and 10-methyl-C16 : 1. The genomic DNA G+C content of the isolate was 69.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 6014T fell within the radius of the suborder Streptosporangineae, in which the strain formed a distinct lineage next to genera of the family Streptosporangiaceae. Based on data from this polyphasic study, strain 6014T can be readily distinguished from previously described organisms and represents a member of a novel species within a new genus in the suborder Streptosporangineae. The name Sinosporangium album gen. nov., sp. nov. is proposed with 6014T (=DSM 45181T =KCTC 19655T) as the type strain.

Abstract
A novel actinomycete producing 2-allyloxyphenol, designated strain MS1/7(T), was isolated from sediments of the Sundarbans mangrove forest, India. Growth on International Streptomyces Project (ISP) media 2, 3, 4, 5 and 7 produced olive green to grey aerial hyphae that carried smooth-surfaced spores in a flexuous (Rectiflexibiles) arrangement. The strain contained ll-diaminopimelic acid, but no diagnostic sugars in whole-cell hydrolysates. Hexa-, octa- and a minor amount of tetra-hydrogenated menaquinones with nine isoprene units [MK-9 (H(4), H(6), H(8) and H(10))] were present as isoprene analogues. Diagnostic phospholipids were phosphatidylethanolamine and diphosphatidylglycerol. The predominant fatty acids were anteiso-C(15 : 0) (34.80 %), iso-C(16 : 0) (16.45 %), C(16) (10.53 %) and anteiso-C(17 : 0) (10.92 %). The strain showed greater than 99 % 16S rRNA gene sequence similarity to the type strains of several recognized species of the genus Streptomyces, but in the phylogenetic tree based on 16S rRNA gene sequences it formed a distinct phyletic line and demonstrated closest relationships to viomycin-producers (Streptomyces californicus NRRL B-1221(T), Streptomyces floridae MTCC 2534(T) and Streptomyces puniceus NRRL B-2895(T)). However, strain MS1/7(T) could be distinguished from these and other closely related species based on low levels of DNA-DNA relatedness (<44 %) and disparate physiological features, principally amino acid utilization and growth in NaCl. Strain MS1/7(T) is therefore suggested to represent a novel species of the genus Streptomyces, for which the name Streptomyces sundarbansensis sp. nov. is proposed. The type strain is MS1/7(T) ( = MTCC 10621(T) = DSM 42019(T)).

Abstract
An actinomycete, designated CPCC 202699T, was isolated from soil in Qinghai province, China, and its taxonomic status was established. Strain CPCC 202699Tcontainedmeso-diaminopimelic acid in its peptidoglycan, arabinose and galactose as the diagnostic sugars in whole-cell hydrolysates, a phospholipid pattern consisting mainly of phosphatidylethanolamine, phosphatidylmethylethanolamine and phosphatidylcholine, MK-9(H4) as the predominant menaquinone and iso-C16 : 0(18.8 %), iso-C15 : 0(18.1 %), iso-C14 : 0(14.2 %), C16 : 1cis9 (10.9 %) and C17 : 1cis9 (10.3 %) as the major fatty acids. In the phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 202699Tformed a separate branch within the genusAmycolatopsis. However, strain CPCC 202699Tshowed low 16S rRNA gene sequence similarities (<97.0 %) with type strains of species with validly published names in the genusAmycolatopsis. On the basis of genotypic and phenotypic differences from the closest phylogenetic neighbours of strain CPCC 202699T, a novel species,Amycolatopsis xylanicasp. nov., is proposed. The type strain is CPCC 202699T(=DSM 45285T=KCTC 19581T=CCM 7627T).

Abstract
The taxonomic position of a rhizosphere soil isolate, designated strain SR8.15T, was determined by using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of the strain showed that it formed a well-separated sub-branch within the radiation encompassing the genus Saccharopolyspora. Highest levels of 16S rRNA gene sequence similarity were found between strain SR8.15T and Saccharopolyspora shandongensis CGMCC 4.3530T (98.9 %) and Saccharopolyspora spinosa DSM 44228T (98.5 %). However, these strains shared low levels of DNA–DNA relatedness (<26 %). Strain SR8.15T had chemical characteristics consistent with its classification in the genus Saccharopolyspora. It contained meso-diaminopimelic acid as the diagnostic diamino acid. Whole-cell hydrolysates contained arabinose and galactose. The diagnostic phospholipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylinositol. The main menaquinone was MK-9(H4). No mycolic acid was detected. The predominant cellular fatty acid was iso-C16 : 0. The G+C content of the genomic DNA of strain SR8.15T was 70.3 mol%. Strain SR8.15T had a phenotypic profile that readily distinguished it from recognized representatives of the genus Saccharopolyspora. It is evident from its combined genotypic and phenotypic properties that strain SR8.15T represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora phatthalungensis sp. nov. is proposed. The type strain is SR8.15T (=TISTR 1921T=BCC 35844T=NRRL B-24798T).

Abstract
A Gram-stain-positive, aerobic actinomycete, strain YIM 60513T, was isolated from the stem of Gloriosa superba L. collected from tropical rainforest at Xishuangbanna, Yunnan Province, south-west China. 16S rRNA gene sequence analysis indicated that strain YIM 60513T belonged to the genus Saccharopolyspora and was closely related to Saccharopolyspora gregorii NCIB 12823T (99.1 % similarity) and Saccharopolyspora cebuensis SPE 10-1T (97.3 % similarity). Data for the predominant quinone [MK-9(H4)], major fatty acids (iso-C16 : 0, anteiso-C17 : 0 and C17 : 1
cis9) and G+C content of the genomic DNA (71.6 mol%) were similar to those for members of the genus Saccharopolyspora. The level of DNA–DNA relatedness between strain YIM 60513T and S. gregorii NCIB 12823T was 43 %. The combination of phylogenetic analysis, phenotypic differences, chemotaxonomic characteristics and DNA–DNA hybridization data supported the view that strain YIM 60513T should be distinguished from S. gregorii NCIB 12823T and S. cebuensis SPE 10-1T. Strain YIM 60513T therefore represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora gloriosae sp. nov. is proposed. The type strain is YIM 60513T (=KCTC 19243T =CCTCC AA 207006T).

Abstract
A novel actinomycete, designated strain OU-40(T), was isolated from farm soil collected from the Hyderabad region of Andhra Pradesh, southern India. The strain was found to have morphological and chemotaxonomic characteristics typical of species of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain OU-40(T) belonged to the genus Streptomyces, and was related most closely to Streptomyces pactum NBRC 13433(T) (99.0 % sequence similarity), Streptomyces olivaceus NBRC 12805(T) (99.0 %) and Streptomyces parvulus NBRC 13193(T) (98.8 %). Strain OU-40(T) could be distinguished from the type strains of its closest phylogenetic relatives based on levels of DNA-DNA relatedness and comparison of morphological and phenotypic data. It is therefore concluded that strain OU-40(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces hyderabadensis sp. nov. is proposed. The type strain is OU-40(T) (=CCTCC AA 209024(T) =PCM 2692(T)).

Abstract
A novel actinomycete, designated strain OU-63T, was isolated from garden soil collected on the campus of Osmania University in Hyderabad, southern India. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Streptomyces, and was related most closely to Streptomyces chartreusis NBRC 12753T (98.6% similarity). However, the mean level of DNA-DNA relatedness between the two strains was only 25+/-1.73%. Based on DNA-DNA relatedness, morphological and phenotypic data, strain OU-63T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces osmaniensis sp. nov. is proposed. The type strain is OU-63T (=CCTCC AA209025T =PCM 2690T).

Abstract
The taxonomic position of a Gram-stain-positive, aerobic strain, designated 03-9939(T), isolated from a soil sample collected from Xinjiang Province, China, was established using a polyphasic approach. Whole-cell hydrolysates of strain 03-9939(T) contained galactose and ribose as diagnostic sugars and meso-diaminopimelic acid as the diamino acid. The predominant menaquinone was MK-9(H4). The phospholipids consisted of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine. The major fatty acids were iso-C(16 : 0) (61.5 %) and iso-C(16 : 1) H (11.6 %). The genomic DNA G+C content was 68.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 03-9939(T) should be placed within the family Actinosynnemataceae, in which the strain formed a distinct lineage. Signature nucleotides in the 16S rRNA gene sequence showed that the strain contained a genus-specific diagnostic nucleotide signature pattern. The combination of phylogenetic analysis, phenotypic characteristics and chemotaxonomic data supported the conclusion that strain 03-9939(T) represents a novel species in a new genus of the family Actinosynnemataceae, for which the name Alloactinosynnema album gen. nov., sp. nov. is proposed. Strain 03-9939(T) (=DSM 45114(T) =KCTC 19294(T) =CCM 7461(T)) is the type strain of Alloactinosynnema album.

Abstract
The taxonomic status of a bacterium isolated from a patient with bronchial carcinoma was established using a polyphasic taxonomic approach. The strain had morphological and chemotaxonomic characteristics consistent with those of members of the genus Saccharopolyspora. The generic assignment was confirmed by comparative analysis of the 16S rRNA gene sequence, which showed that the strain constituted a distinct phyletic line, displaying 93.5-96.9 % sequence similarity with respect to members of the genus Saccharopolyspora. The isolate was distinguished from the type strains of recognized members of the genus Saccharopolyspora by means of various biochemical tests. The genotypic and phenotypic data obtained demonstrated that strain IMMIB L-1070(T) represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora rosea sp. nov. is proposed. The type strain is IMMIB L-1070(T) (=DSM 45226(T)=CCUG 56401(T)).

Abstract
The taxonomic status of an unknown actinomycete isolated from a sand-dune soil was established using a polyphasic approach. Isolate S186(T) had chemotaxonomic and morphological properties consistent with its classification in the genus Nocardiopsis, grew on agar plates at NaCl concentrations of up to 15 % (w/v) and formed a distinct phyletic line in the Nocardiopsis 16S rRNA gene sequence tree. Its closest phylogenetic neighbours were Nocardiopsis chromatogenes, Nocardiopsis composta, Nocardiopsis gilva and Nocardiopsis trehalosi, with sequence similarity to the various type strains of 96.9 %, but it was readily distinguished from the type strains of these and related species using a range of phenotypic properties. It is apparent from the genotypic and phenotypic data that strain S186(T) belongs to a novel species of the genus Nocardiopsis, for which the name Nocardiopsis arabia sp. nov. is proposed. The type strain is S186(T) (=CGMCC 4.2057(T) =DSM 45083(T)).

Abstract
A Gram-positive, aerobic, non-motile, non-acid-alcohol-fast strain, designated YIM 61095(T), was isolated from the root of Maytenus austroyunnanensis collected from a tropical rainforest of Xishuangbanna in Yunnan Province, south-west China. Strain YIM 61095(T) exhibited chemotaxonomic and morphological characteristics that were consistent with members of the genus Saccharopolyspora. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 61095(T) was a member of the genus Saccharopolyspora and was most closely related to Saccharopolyspora flava AS 4.1520(T) (97.7% sequence similarity). The major fatty acids were iso-C(15:0), iso-C(16:0), iso-C(17:0) and anteiso-C(17:0). The predominant quinone detected was MK-9(H(4)). The DNA G+C content was 66.2 mol%. The phenotypic characteristics and DNA-DNA hybridization relatedness data indicated that strain YIM 61095(T) should be distinguished from Saccharopolyspora flava AS 4.1520(T). On the basis of the evidence presented in this study, strain YIM 61095(T) represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora endophytica sp. nov. is proposed. The type strain is YIM 61095(T) (=KCTC 19397(T)=CCTCC AA 208003(T)).

Abstract
An actinomycete, strain 4776T, was isolated from soil collected from Emei Mountain in Sichuan Province, China. The taxonomic status of this strain was established using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of streptomycetes. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that the novel isolate belongs to the genus Streptomyces and consistently falls into a clade together with Streptomyces prasinopilosus DSM 40098T, Streptomyces prasinus JCM 4603T, Streptomyces bambergiensis DSM 40590T, Streptomyces hirsutus DSM 40095T and Streptomyces cyanoalbus DSM 40198T. However, DNA–DNA relatedness and phenotypic data distinguished strain 4776T from these phylogenetically related type strains. It is therefore concluded that strain 4776T (=CGMCC 4.3504T=DSM 41884T) represents a novel species of the genus Streptomyces, for which the name Streptomyces emeienseis sp. nov. is proposed.

Abstract
The taxonomic position of a soil isolate, strain Z6T, was established using a polyphasic approach. The organism showed a range of chemical and morphological properties consistent with its classification in the genus Lechevalieria. An almost complete 16S rRNA gene sequence determined for the strain was aligned with corresponding sequences of representatives of the genus Lechevalieria and related taxa using three tree-making algorithms. The organism formed a distinct phyletic line within the evolutionary radiation occupied by the genus Lechevalieria and was more closely related to the type strain of Lechevalieria aerocolonigenes than to that of Lechevalieria flava. Strain Z6T could be distinguished from both these strains using DNA–DNA relatedness data and by a combination of phenotypic properties. The combined genotypic and phenotypic data show that strain Z6T should be assigned to the genus Lechevalieria as a representative of a novel species. The name proposed for this new taxon is Lechevalieria fradiae sp. nov. The type strain is Z6T (=CGMCC 4.3506T=JCM 14205T).

Abstract
The taxonomic position of an unknown actinomycete isolated from a sand dune soil sample collected at Borg El-Arab in Egypt was established using a combination of genotypic and phenotypic data. Isolate S136(T) had chemotaxonomic and morphological properties consistent with its classification in the genus Nonomuraea and formed a distinct phyletic line in the Nonomuraea 16S rRNA gene tree. It was most closely related to the type strains of Nonomuraea helvata, Nonomuraea kuesteri and Nonomuraea turkmeniaca, sharing 16S rRNA gene similarities with these species of 97.1, 97.2 and 97.3%, respectively. The organism was distinguished from representatives of validly described Nonomuraea species using a range of phenotypic properties. It is apparent that the isolate belongs to a novel Nonomuraea species. The name proposed for this taxon is Nonomuraea aegyptia sp. nov., the type strain is S136(T) (=CGMCC 4.2054(T) = DSM 45082(T)).

Abstract
An actinomycete, strain FXJ46T, was isolated from cypress forest soil in northern China and shown to have chemotaxonomic and morphological properties consistent with streptomycetes. It developed greyish aerial mycelium and pinkish-brown substrate mycelium on oatmeal agar. Phylogenetic analyses based on an almost complete 16S rRNA gene sequence of the strain and on the 120 nucleotide variable γ-region of this molecule showed that it formed a distinct (but closely associated) line with Streptomyces griseoaurantiacus DSM 40430T in Streptomyces trees. However, the DNA–DNA relatedness between the two strains was only 48·8 %. A number of phenotypic properties also readily distinguished the isolate from S. griseoaurantiacus and related Streptomyces species with validly published names. It is proposed, therefore, that this organism be classified as a novel species of the genus Streptomyces, for which the name Streptomyces jietaisiensis sp. nov. is proposed. The type strain is FXJ46T (=AS 4.1859T=JCM 12279T).

Abstract
Two soil isolates, strains 80-60T and 3.24T, were shown to have chemical and morphological properties consistent with their classification in the genus Actinomadura. The almost complete 16S rDNA sequences generated for the two organisms were aligned with available sequences of representatives of the genus Actinomadura and related taxa. It was apparent from the resultant phylogenetic trees that each of the strains formed a distinct phyletic line within the evolutionary radiation occupied by the genus Actinomadura. The two organisms could also be distinguished from one another and from representatives of all the validly described species of Actinomadura using a set of phenotypic properties. It is proposed that strains 3.24T (=AS 4.1522T =IFO 16341T) and 80-60T (=AS 4.1202T =IFO 14668T =JCM 16161T) be classified in the genus Actinomadura as Actinomadura catellatispora sp. nov. and Actinomadura glauciflava sp. nov., respectively.

Abstract
The taxonomic position of two soil isolates, strains A288(T) and A290(T) [provisionally assigned to the genus Actinomadura] was clarified in a polyphasic study. The organisms showed a combination of chemotaxonomic and morphological properties typical of actinomadurae. They also formed distinct phyletic lines in the 16S rRNA Actinomadura gene tree; strain A288(T) was associated with A. nitritigenes whereas strain A290(T) was closely related to a group that consisted of A. citrea, A. coerulea, A. glauciflava, A. luteofluorescens and A. verrucosospora. Strains A288(T) and A290(T) showed key phenotypic features which readily distinguish them from one another and from representatives of related validly described species of Actinomadura. It is proposed that the two organisms be classified as new species of the genus Actinomadura. The names proposed for the new taxa are Actinomadura mexicana (A290(T) = DSM 44485(T) = NRRL B-24203(T)), and Actinomadura meyerii (A288(T) = DSM 44485(T) = NRRL B-24203(T)).
