Abstract
A novel cellulase-producing actinobacterium, designated strain NEAU-L178T, was isolated from soil sample collected from Qiqihaer, Heilongjiang Province, PR China. A polyphasic study was carried out to determine the taxonomic status of the strain. On the basis of 16S rRNA gene sequence analysis, strain NEAU-L178T should be classified into the genus
Nonomuraea
and is closely related to
Nonomuraea cavernae
SYSU K10005T (99.31 % 16S rRNA gene sequence similarity),
Nonomuraea glycinis
NEAU-BB2C19T (98.75 %),
Nonomuraea guangzhouensis
NEAU-ZJ3T (98.75 %) and ‘Nonomuraea rhizosphaerae’ NEAU-mq18T (98.34 %). The digital DNA–DNA hybridization values between them are 27.1, 26.1, 42.0 and 30.9 %, and the whole-genome average nucleotide identity values between them are 83.1, 82.3, 90.3 and 85.8 %, respectively. The whole-cell hydrolysates contained glucose, ribose, arabinose and madurose. The menaquinones were identified as MK-9(H0), MK-9(H4) and MK-9(H2). The major fatty acids were C16 : 0, iso-C17 : 0 and C17 : 0 10-methyl. The detected polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylinositol and three unidentified phospholipids. The genomic DNA G+C content was 69.7 mol%. In addition, whole-genome analysis indicated that strain NEAU-L178T had the potential to degrade cellulose. Based on the phenotypic, genotypic, chemotaxonomic and phylogenetic data, strain NEAU-L178T can be differentiated from its close phylogenetic relatives and represents a novel species of the genus
Nonomuraea
, for which the name Nonomuraea aurantiaca sp. nov. is proposed. The type strain is NEAU-L178T (=JCM 34799T=CGMCC 4.7741T).

6K102T,
Nonomuraea rubra
DSM 43768T,
Nonomuraea diastatica
KC712T and
Nonomuraea helvata
IFO 14681T. The strain formed an extensively branched substrate and aerial mycelia. The whole-cell hydrolysates contained meso-diaminopimelic acid as the diagnostic diamino acid, with glucose, madurose, mannose and ribose as the whole-cell sugars. The polar lipids were diphosphatidylglycerol, phosphotidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylmonomethylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, two unidentified phospholipids, three unidentified sugar-containing phosphoaminolipids, an unidentified glycolipid and two unidentified lipids. The predominant menaquinone was MK-9(H4), with minor amounts of MK-9(H0), MK-9(H2) and MK-9(H6). Major cellular fatty acids (>10%) were iso-C16 : 0 and 10-methyl-C17 : 0. The G+C content of the genomic DNA was 71.0 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between strain NN258T and the reference strains were 79.9–80.9 % and 26.1–27.0 %, respectively. On the basis of phenotypic, genotypic and phylogenetic data, strain NN258T represents a novel species of the genus

Abstract
A novel endophytic actinomycete, designated strain p1410T, was isolated from the root of cattail pollen (Typha angustifolia L.) and characterized using a polyphasic approach. The strain had morphological characteristics and chemotaxonomic properties identical to those of members of the genus Nonomuraea. It produced spiral chains of spores on aerial mycelium as well as forming a pseudosporangium. Whole-cell hydrolysates contained meso-diaminopimelic acid, glucose, ribose and madurose. The menaquinones detected were MK-9(H2), MK-9(H4) and MK-9(H0). The major fatty acids were 10-methyl C17 : 0, iso-C16 : 0 and C17 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol mannoside and an unknown glycolipid. The DNA G+C content of the draft genome sequence, consisting of 11.4 Mbp, was 70.9 mol%. Phylogenetic analysis of 16S rRNA gene sequences showed that strain p1410T belongs to the genus Nonomuraea with the highest sequence similarity to Nonomuraea candida HMC10T (98.6 %), but phylogenetically clustered with Nonomuraea endophytica YIM 65601T (98.4 %) and Nonomuraea longicatena NRRL 15532T (98.3 %). Based on its phenotypic characteristics, DNA-DNA relatedness and average nucleotide identity, the strain is considered to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea typhae sp. nov. is proposed. The type strain is p1410T (=CCTCC AA 2019044T=JCM 33461T).

Abstract
Strain DRQ-2T (type strain of Nonomuraea indica) is worthy for genome sequencing, due to its ability to produce a wide variety of industrially important enzymes such as amylase, asparaginase, cellulase, gelatinase, glutaminase, and protease. Genome sequencing and comparison of strain DRQ-2T is described in the present work. The genome size was estimated to be 8,288,417 (bp) that consisted of 59 contigs. The G + C content of the genome was 72.4%. A total of 7730 genes were predicted with two rRNAs and 64 tRNAs. The genome analysis of the strain DRQ-2T showed the presence of a wide range of secondary metabolite gene clusters. Pan-Genomes Analysis Pipeline (PGAP) indicated that strain DRQ-2T had large numbers of unique genes. The majority of N. indica DRQ-2T genes encode for hypothetical proteins, indicating the functions of these ortholog clusters were still remain to be determined.

Abstract
A novel endophytic actinomycete strain GKU 173T isolated from the roots of Acacia mangium Willd. showed potential plant growth promoting (PGP) activity. Phylogenetic analysis, based on 16S rRNA gene, indicated that strain GKU 173T was the most closely related to Fodinicola feengrottensis HKI 0501T—the only species in the genus Fodinicola. Morphology and chemotaxonomy of strain GKU 173T indicated that it belongs to the genus Fodinicola by having meso-diaminopimelic acid in the cell wall and xylose as the characteristic cell-wall sugars. The cellular fatty acid profile mainly comprised iso-C16:0, anteiso-C17:0, iso-C18:0, and iso-C17:0. The major menaquinones were MK-9(H4), MK-9(H6), and MK-9(H8). The main polar phospholipids contained diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), and phosphatidylinositol (PI). Genome analysis signified DNA G+C content of 67.81 mol%. The level of digital DNA-DNA relatedness between strain GKU 173T and the type strain was 21.30%. On the basis of polyphasic characteristics, strain GKU 173T clearly represents a novel species of the genus Fodinicola, for which the name Fodinicolaacaciae sp. nov. (= TBRC 10620T = NBRC 114213T) is proposed. Furthermore, genome analysis of both strains suggested that members of the genus Fodinicola are promising sources of beneficial PGP-actinomycetes and novel secondary metabolites.

Abstract
Five actinobacteria isolates, KC201T, KC401, KC310T, KC712T and 6K102T, were recovered from the Karakum Desert during an investigation of novel actinobacteria with biotechnological potential. A polyphasic approach confirmed the affiliation of the strains to the genus Nonomuraea. The strains showed chemotaxonomic and morphological properties consistent with their classification in the genus Nonomuraea. Furthermore, these strains clearly distinguished and formed well supperted clades in phylogenetic and phylogenomic trees. Low ANI and dDDH values and distinguishing phenotypic properties between isolates KC201T, KC310T, KC712T and 6K102T showed that these strains belonged to novel Nonomuraea species, the names proposed for these taxa are Nonomuraea deserti sp. nov., Nonomuraea diastatica sp. nov., Nonomuraea longispora sp. nov. and Nonomuraea mesophila sp. nov., with the type strains KC310T (=CGMCC 4.7331T =DSM 102919T =KCTC 39774T), KC712T (=CGMCC 4.7334T =DSM 102925T =KCTC 39776), KC201T (=CGMCC 4.7339T =DSM 102917T =KCTC 39781T) and 6K102T (=CGMCC 4.7541T =JCM 32916), respectively.

Abstract
A novel actinomycete, designated strain NEAU-mq18T, was isolated from the rhizosphere soil of a rubber tree (Hevea brasiliensis Muell. Arg) collected from Xianglu Mountain in Heilongjiang Province, northeast China, and subjected to a polyphasic taxonomic study. The 16S rRNA gene sequence analysis showed that the isolate belongs to the genus Nonomuraea with high sequence similarity to Nonomuraea guangzhouensis NEAU-ZJ3T (98.5%). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain clusters phylogenetically with N. guangzhouensis NEAU-ZJ3T and Nonomuraea glycinis NEAU-BB2C19T. Moreover, key chemotaxonomic properties including the major menaquinones, fatty acid composition and phospholipid profile also confirmed the affiliation of the strain to the genus Nonomuraea. However, some physiological, morphological and biochemical properties, and low DNA-DNA relatedness values, enabled the strain to be differentiated from closely related species of the genus Nonomuraea. Thus, strain NEAU-mq18T is concluded to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea rhizosphaerae sp. nov. is proposed. The type strain is NEAU-mq18T (=CGMCC 4.7431T=DSM 105761T).

Abstract
A novel actinomycete strain, designated GKU 128T, isolated from the roots of an Indian oak tree [Barringtonia acutangula (L.) Gaertn.] at Khao Khitchakut district, Chantaburi province, Thailand, was characterized by using a polyphasic approach. The strain formed a branched substrate and aerial mycelia which differentiated into straight to flexuous chains of smooth-ornamented spores. Analysis of the cell wall revealed the presence of meso-diaminopimelic acid and N-acetylmuramic acid in the peptidoglycan. The whole-cell sugars were glucose, madurose, mannose, rhamnose and ribose. Mycolic acids were absent. The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositolmannoside. The predominant menaquinones were MK-9(H6), MK-9(H8), MK-9(H0) and MK-9(H4). The major fatty acids were C16 : 0, C18 : 1ω9c and 10-methyl C18 : 0 (tuberculostearic acid). The genomic DNA G+C content was 70.5 mol%. Based on 16S rRNA gene sequence analysis, strain GKU 128T was closely related to the type strains of Actinomadura nitritigenes NBRC 15918T (99.2 % sequence similarity) and Actinomadura fibrosa JCM 9371T (98.7 %). The levels of DNA-DNA relatedness between strain GKU 128T and the closely related type species were less than 19 %. On the basis of phenotypic and genotypic characteristics, strain GKU 128T could be distinguished from its closely related type strains and represents a novel species of the genus Actinomadura, for which the name Actinomadura barringtoniae sp. nov. (=TBRC 7225T=NBRC 113074T) is proposed.

Abstract
Two novel bacterial strains were isolated from the roots of tomato plants (Solanum lycopersicum L.) from Dengfeng, Henan Province, China. Phylogenetic analysis of 16S rRNA gene sequences showed that the isolates NEAU-DE8(1)T and NEAU-HE1(2) are closely related to one another (99.6% similarity) and are closely relate to Nonomuraea zeae NEAU-ND5T (98.3, 98.3%) and Nonomuraea gerenzanensis DSM 100948T (98.3, 98.0%). Phylogenetic trees constructed based on 16S rRNA gene sequences revealed that both strains grouped with N. zeae NEAU-ND5T within the clade comprising the members of the genus Nonomuraea. Moreover, key chemotaxonomic properties including major menaquinones, fatty acid composition and phospholipid profiles also confirmed the affiliation of the two strains to the genus Nonomuraea. However, DNA-DNA hybridization data, together with physiological and morphological properties, showed that two isolates could be readily distinguished from their close phylogenetic relatives. Thus, on the basis of these phenotypic and genotypic data, strains NEAU-DE8(1)T and NEAU-HE1(2) are concluded to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea lycopersici sp. nov. is proposed. The type strain is NEAU-DE8(1)T (= CGMCC 4.7412T = DSM 104642T).

Abstract
A novel actinomycete, designated strain NEAU-BB2C19T, was isolated from the root of black soya bean [Glycine max (L.) Merr] collected from Harbin, Heilongjiang Province, China, and characterized using a polyphasic approach. The strain was an aerobic, Gram-stain-positive actinomycete that formed extensively branched substrate mycelium and aerial hyphae. The predominant menaquinones were MK-9(H2) and MK-9(H0). The major cellular fatty acid profile consisted of iso-C16 : 0, 10-methyl C17 : 0 and 10-methyl C18 : 0. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, phosphatidylglycerol and glycolipid. The DNA G+C content was 68.2±0.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-BB2C19T should be assigned to the genus Nonomuraea and formed a distinct branch with its closest neighbour Nonomuraea guangzhouensis NEAU-ZJ3T (98.75 % 16S rRNA gene sequence similarity). The morphological and chemotaxonomic properties of the strain were also consistent with those of members of the genus Nonomuraea. A combination of DNA-DNA hybridization results and some phenotypic characteristics indicated that strain NEAU-BB2C19T could be clearly differentiated from its closest phylogenetic relative. Thus, the strain is concluded to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea glycinis sp. nov. is proposed. The type strain is NEAU-BB2C19T (=CGMCC 4.7430T=DSM 104838T).

Abstract
A novel actinobacterial strain, designated SYSU K10005T, was isolated from a soil sample collected from a karst cave in Xingyi county, Guizhou province, south-west China. The taxonomic position of the strain was investigated using a polyphasic approach. Cells of the strain were aerobic and Gram-stain-positive. On the basis of 16S rRNA gene sequence analysis, strain SYSU K10005T was most closely related to the type strains of the genus Nonomuraea, and shared highest sequence similarity of 98.4 % with Nonomuraea candida HMC10T. DNA-DNA hybridization values between the two strains were less than 70 %. The whole-cell hydrolysates of strain SYSU K10005T contained meso-diaminopimelic acid (diagnostic diamino acid), and arabinose, madurose and rhamnose (whole-cell sugars). The major isoprenoid quinone was MK-9(H4), while the major fatty acids were iso-C16 : 0, 10-methyl C17 : 0, C17 : 1ω8c and C17 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, hydroxyl-phosphatidylethanolamine, lyso-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, an unidentified lipid, two unidentified ninhydrin-positive phosphoglycolipids and two unidentified phospholipids. The genomic DNA G+C content of strain SYSU K10005T was 64.2 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU K10005T can be characterized to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea cavernae sp. nov. is proposed. The type strain is SYSU K10005T (=KCTC 39805T=CGMCC 4.7368T).

Abstract
Strain ATCC 39727, which produces the antibiotic A40926 (the natural precursor of the antibiotic dalbavancin), was isolated from a soil sample collected in India, and it was originally classified as a member of the genus Actinomadura on the base of morphology and cell-wall composition. A phylogenetic analysis based on 16S rRNA gene sequences indicates that the strain forms a distinct clade within the genus Nonomuraea, and it is most closely related to Nonomuraea angiospora DSM 43173T (98.72 % similarity) and Nonomuraea jabiensis A4036T (98.69 %). The strain forms an extensively branched substrate mycelium and aerial hyphae that form spiral chains of spores with ridged surfaces. The cell wall contains meso-diaminopimelic acid and the whole-cell sugars are glucose, ribose, galactose, mannose and madurose (madurose as the diagnostic sugar). The N-acyl type of muramic acid is acetyl. The predominant menaquinone is MK-9(H4), with minor amounts of MK-9(H2), MK-9(H6) and MK-9(H0). The polar-lipid profile includes diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylmethylethanolamine, hydroxyphosphatidylmethylethanolamine, phosphatidylinositol and a series of uncharacterized phospholipids, glycolipids and phosphoglycolipids. The major cellular fatty acids are iso-C16 : 0 and 10-methyl C17 : 0. The genomic DNA G+C content is 71.2 mol%. Significant differences in the morphological, chemotaxonomic and biochemical data, together with DNA-DNA relatedness between strain ATCC 39727 and closely related type strains, clearly demonstrated that strain ATCC 39727 represents a novel species of the genus Nonomuraea, for which the name Nonomuraea gerenzanensis sp. nov. is proposed. The type strain is ATCC 39727T ( = DSM 100948T).

Abstract
A polyphasic approach was used to verify the novel actinomycete, strain 1SM4-01T, isolated from mangrove sediment collected from Ranong Province, Thailand. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the organism was a member of the genus Nonomuraea and was most closely related to Nonomuraea syzygii GKU 164T (98.7 % sequence similarity), Nonomuraea rhizophila YIM 67092T (98.4 %), Nonomuraea solani NEAU-Z6T (98.4 %), Nonomuraea monospora PT708T (98.3 %) and Nonomuraea thailandensis KC-061T (98.2 %). The strain produced branching aerial mycelium which differentiated into straight chains of rough-surfaced spores borne at the end of a short sporophore. The whole-cell hydrolysates contained meso-diaminopimelic acid as the diagnostic diamino acid, with madurose, mannose and ribose as the main sugars. MK-9(H4) was a major menaquinone of this strain. The acyl type of peptidoglycan was N-acetyl. The predominant cellular fatty acids were C17 : 1ω8c and iso-C16 : 0. Phospholipids consisted of diphosphatidylglycerol, hydroxy-phosphatidylethanolamine, hydroxy-phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, aminophospholipids and unidentified lipids. The G+C content of the genomic DNA was 70.4 mol%. On the basis of phenotypic characteristics, DNA-DNA relatedness and phylogenetic distinctiveness, strain 1SM4-01T represents a novel species of the genus Nonomuraea, for which the name Nonomuraea purpurea sp. nov. is proposed. The type strain is 1SM4-01T (=BCC 60397T=NBRC 109647T).

Abstract
A novel actinobacterium, designated strain NEAU-ND5T, was isolated from the rhizosphere of corn (Zea mays L.) collected in Heilongjiang Province, north-east China, and characterized using a polyphasic approach. 16S rRNA gene sequence analysis showed that strain NEAU-ND5T was a member of the genus Nonomuraea, with highest sequence similarities to Nonomuraea jabiensis A4036T (98.29 %), Nonomuraea rosea GW12687T (98.25 %), Nonomuraea candida HMC10T (98.22 %), Nonomuraea rhizophila YIM 67092T (98.04 %) and Nonomuraea kuesteri NRRL B-24325T (98.04 %). Similarities to other type strains of the genus Nonomuraea were lower than 98 %. Morphological and chemotaxonomic properties of strain NEAU-ND5T were also consistent with the description of the genus Nonomuraea. The cell wall contained meso-diaminopimelic acid and the whole-cell sugars were glucose, ribose and madurose. The phospholipid profile consisted of diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylmonomethylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The major menaquinones were MK-9(H4), MK-9(H2) and MK-9(H0). The predominant cellular fatty acids were iso-C16:0 and 10-methyl C17:0. A combination of DNA-DNA hybridization results and some phenotypic characteristics demonstrated that strain NEAU-ND5T was clearly distinguished from its closely related Nonomuraea species. Consequently, it is concluded that strain NEAU-ND5T represents a novel species of the genus Nonomuraea, for which the name Nonomuraea zeae sp. nov. is proposed. The type strain is NEAU-ND5T (=CGMCC 4.7280T=DSM 100528T).

Abstract
A novel thermotolerant actinomycete, designated strain 3-33-9BT, was isolated from mushroom compost in Nanning, Guangxi province, China. The strain grew at 25-60 °C, pH 7.0-11.0 and with 0-2.0 % (w/v) NaCl. Strain 3-33-9BT formed extensively branched aerial mycelia and substrate mycelia. Spiral spore chains with one to three turns were composed of about 3-15 non-motile spores with a wrinkled surface. The organism contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. Whole-cell hydrolysates contained madurose, galactose, glucose and ribose. The cellular fatty acid profile mainly consisted of iso-C16 : 0 and C17 : 0. The quinone system was predominantly composed of MK-9(H4). The DNA G+C content of strain 3-33-9BT was 72.5 mol%. The organism showed a combination of morphological and chemotaxonomic properties typical of members of the genus Nonomuraea. Moreover, 16S rRNA gene sequence analysis also showed that the organism belonged to the genus Nonomuraea; in the 16S rRNA gene tree of the genus Nonomuraea, strain 3-33-9BT formed a distinct phyletic line and was most closely related to Nonomuraea fastidiosa NBRC 14680T (97.3 % 16S rRNA gene sequence similarity). However, phenotypic characteristics of strain 3-33-9BT were significantly different from N. fastidiosa NBRC 14680T, and DNA-DNA hybridization showed little relatedness (31.6-35.2 %) between the two strains. Based on the phenotypic and phylogenetic data, strain 3-33-9BT represents a novel species of the genus Nonomuraea, for which the name Nonomuraea thermotolerans sp. nov. is proposed. The type strain is 3-33-9BT ( = ATCC BAA-2629T = CGMCC 4.7161T).

Abstract
The taxonomic position of an endophytic actinomycete, strain GKU 157T, isolated from the roots of a jambolan plum tree (Syzygium cumini L. Skeels) collected at Khao Khitchakut National Park, Chantaburi province, Thailand, was determined using a polyphasic taxonomic approach. 16S rRNA gene sequence analysis revealed that strain GKU 157T belongs to the genus Actinomadura and formed a distinct phyletic line with Actinomadura chibensis NBRC 106107T (98.6 % similarity). Strain GKU 157T formed an extensively branched, non-fragmenting substrate mycelium and aerial hyphae that differentiated into hooked to short spiral chains of about 20 non-motile spores with a warty surface. The cell wall contained meso-diaminopimelic acid and the whole-cell sugars were galactose, glucose, madurose, mannose and ribose. The N-acyl type of muramic acid was acetyl. Mycolic acids were absent. The phospholipids included phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), phosphatidylinositol (PI), phosphatidylinositolmannoside (PIM) and two unknown phospholipids (PLs). The major menaquinone was MK-9(H6) and the predominant fatty acids were C16:0, iso-C16:0, C18:1ω9c, C18:0 and 10-methyl C18:0 (tuberculostearic acid). The genomic DNA G+C content was 73.1 mol%. A combination of DNA–DNA hybridization results and significant differences from related species in cultural, physiological and chemical characteristics indicated that strain GKU 157T represents a novel species of the genus Actinomadura, for which the name Actinomadura syzygii sp. nov. is proposed. The type strain is GKU 157T ( = BCC 70456T = NBRC 110399T).
