Strain D10-9-5T was isolated from mangrove soil in Samut Sakhon province, Thailand. A polyphasic approach was used to determine the taxonomic position of the strain. The strain presented single rough spores on substrate mycelium and no aerial mycelium. Chemotaxonomic data supported the assignment of strain D10-9-5T to the genus Micromonospora based on the presence of meso-diaminopimelic acid and glycolyl muramic acid in the peptidoglycan, ribose, mannose, galactose, xylose and glucose as whole-cell sugars, MK-10(H4) (14.8 %), MK-10(H6) (46.7 %) and MK-10(H8) (27.5 %) as the predominant isoprenoid quinones, iso-C15 : 0 (17.9 %), anteiso-C17 : 0 (14.6 %), iso-C17 : 0 (9.6 %), C17 : 0 (8.0 %), iso-C16 : 0 (7.7 %) and C17 : 1ω8c (7.0 %) as the major cellular fatty acids, and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and phosphatidylethanolamine as the predominant phospholipids in the cell wall. The 16S rRNA gene sequence and phylogenetic analysis showed that strain D10-9-5 was closely related to Micromonospora marina JCM 12870T (99.6 %), Micromonospora coxensis JCM 13248 T (99.4 %), Micromonospora aurantiaca JCM 10878T (99.3 %), Micromonospora humi JCM15292T (99.3 %), Micromonospora halophytica JCM 3125T (99.1%) and Micromonospora chalcea JCM 3031T (99.1 %). Strain D10-9-5T could be clearly distinguished from related members of the genus Micromonospora by its physiological and biochemical characteristics as well as its phylogenetic position and level of DNA–DNA relatedness. Therefore, the strain represents a novel species for which the name Micromonospora maritima sp. nov. is proposed; the type strain is D10-9-5T ( = JCM 17013T = NBRC 108767T = PCU 322T = TISTR 2000T).

The taxonomic position of a novel actinomycete isolate, designated strain GGCR-6T, isolated from the healthy leaves of Xanthium sibiricum collected from the botanic garden of Hunan University of Science and Technology in Hunan province, PR China, was determined by a polyphasic approach. GGCR-6T grew well on ISP series media and formed well-developed, branched substrate hyphae and aerial mycelium that differentiated into straight spore chains consisting of cylindrical spores with smooth surfaces. The diagnostic diamino acid was ll-diaminopimelic acid. The major menaquinones were MK-9(H8), MK-9(H2), MK-9 and MK-9(H6). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphotidylinositol and phosphatidylinositol mannosides. The predominant fatty acids were C16 : 1ω9c, iso-C16 : 0 and C16 : 0. The phenotypic characteristics of GGCR-6T indicated that it represented a member of the genus Streptomyces . Phylogenetic analysis based on the 16S rRNA gene sequence indicated that GGCR-6T was most closely related to Streptomyces cyaneus NRRL B2296T and Streptomyces griseoruber NRRL B1818T. However, the digital DNA–DNA hybridization, the average nucleotide identity and the multi locus sequence analysis evolutionary distance clearly separate GGCR-6T from the phylogenetically closely related species. Furthermore, the novel isolate was distinctly differentiated from S. cyaneus NRRL B2296T and S. griseoruber NRRL B1818T by morphological, physiological and biochemical characteristics. Based on these data, strain GGCR-6T should be designated as a representative of a novel species of the genus Streptomyces , for which the name Streptomyces aquilus sp. nov. is proposed. The type strain is strain GGCR-6T (=CICC 11055T=JCM 33584T).

A cellulose-degrading bacterium, strain FCN3-3T, was isolated from buffalo faeces collected in Nakhonnayok province, Thailand. The strain was characterized based on its phenotypic and genotypic characteristics. Strain FCN3-3T was a Gram-positive, aerobic, spore-forming, rod-shaped bacterium. It contained meso-diaminopimelic acid in cell-wall peptidoglycan. The major menaquinone was MK-7. Anteiso-C15 : 0 (52.5 %), iso-C16 : 0 (18.9 %) and C16 : 0 (9.1 %) were the predominant cellular fatty acids, and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol were the major phospholipids. The DNA G+C content was 58.0 mol%. Phylogenetic analysis using 16S rRNA gene sequences showed that strain FCN3-3T was affiliated to the genus Cohnella and was closely related to Cohnella phaseoli GSPC1T, Cohnella luojiensis HY-22RT and Cohnella hongkongensis HKU3T, with 97.2, 96.8 and 96.3 % sequence similarity, respectively. Strain FCN3-3T could be clearly distinguished from all known species of the genus Cohnella by its physiological and biochemical characteristics as well as its phylogenetic position and level of DNA–DNA relatedness. Therefore, the strain represents a novel species of the genus Cohnella , for which the name Cohnella cellulosilytica sp. nov. is proposed; the type strain is FCN3-3T ( = KCTC 13645T = TISTR 1996T = PCU 323T).

A novel halophilic, filamentous, actinomycete strain, designated CXB832T, was isolated from a salt pond in Qingdao, China. Optimal growth occurred at 37 °C, pH 7.0–8.0 and 9–12 % (w/v) NaCl. Strain CXB832T formed pale yellow to deep yellow branched substrate mycelium without fragmentation. Abundant white aerial mycelium differentiated into long chains of spores and the spores were rod-shaped with smooth surfaces. Strain CXB832T contained meso-diaminopimelic acid as the diagnostic diamino acid of the cell-wall peptidoglycan, and glucose and xylose as the major whole-cell sugars. The phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phospholipids, glycolipid and unidentified lipids. MK-10(H8), MK-9(H8), MK-10(H2) and MK-10(H6) were the predominant menaquinones. The major fatty acids were i-C16 : 0 (30.71 %), ai-C17 : 0 (13.31 %) and C16 : 0 (11.28 %). The G+C content of the DNA was 60.1 mol%. Comparative analysis of 16S rRNA gene sequences showed that the novel strain was most closely related to genera within the family Nocardiopsaceae , but formed a separate lineage. The highest sequence similarities were to Nocardiopsis arabia DSM 45083T (95.4 %) and Haloactinospora alba DSM 45015T (94.9 %). On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain CXB832T represents a new genus and novel species in the family Nocardiopsaceae , for which the name Salinactinospora qingdaonensis gen. nov., sp. nov. is proposed. The type strain of the type species is CXB832T ( = DSM 45442T = LMG 25567T).

Daqu is a fermentation starter used in the production of Chinese liquors. A thermophilic bacterium, designated strain H-18T, was isolated from a high-temperature Daqu sample collected from the manufacturing process of a sesame-flavoured liquor in Shandong province, China. It was investigated in a taxonomic study using a polyphasic approach. Strain H-18T formed white aerial mycelium and greyish-yellow substrate mycelium, bearing single endospores on aerial and substrate hyphae or on unbranched short sporophores. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The major fatty acids were iso-C15 : 0 and iso-C17 : 0. The predominant menaquinone was MK-7. These chemotaxonomic properties are similar to those of members of the genus Thermoactinomyces . The G+C content of the genomic DNA was 49.1 mol%. 16S rRNA gene sequence comparisons indicated that strain H-18T was most closely related to Thermoactinomyces vulgaris KCTC 9076T (96.42 % similarity), Thermoactinomyces intermedius KCTC 9646T (96.06 %), Laceyella putida KCTC 3666T (96.32 %) and Laceyella sacchari KCTC 9790T (95.55 %). Strain H-18T showed low DNA–DNA relatedness (40.8, 33.4, 20.0 and 14.4 %) with the above strains. Based on morphological and chemotaxonomic characteristics, DNA–DNA hybridization data and physiological properties, strain H-18T represents a novel species of the genus Thermoactinomyces , for which the name Thermoactinomyces daqus sp. nov. is proposed. The type strain is H-18T ( = DSM 45914T = CICC 10681T).

During a bioprospection of bacteria with antimicrobial activity, the actinomycete strain A38T was isolated from a sediment sample of the Carpintero river located in the Gran Piedra Mountains, Santiago de Cuba province (Cuba). This strain was identified as a member of the genus Micromonospora by means of a polyphasic taxonomy study. Strain A38T was an aerobic Gram-positive filamentous bacterium that produced single spores in a well-developed vegetative mycelium. An aerial mycelium was absent. The cell wall contained meso-diaminopimelic acid and the whole-cell sugars were glucose, mannose, ribose and xylose. The major cellular fatty acids were isoC15:0, 10 methyl C17:0, anteiso-C17:0 and iso-C17:0. The predominant menaquinones were MK-10(H4) and MK-10(H6). Phylogenetic analysis of 16S rRNA gene sequences revealed that this strain was closely related to Micromonospora tulbaghiae DSM 45142T (99.5 %), Micromonospora citrea DSM 43903T (99.4 %), Micromonospora marina DSM 45555T (99.4 %), Micromonospora maritima DSM 45782T (99.3 %), Micromonospora sediminicola DSM 45794T (99.3 %), Micromonospora aurantiaca DSM 43813T (99.2 %) and Micromonospora chaiyaphumensis DSM 45246T (99.2 %). The results of OrthoANIu analysis showed the highest similarity to Micromonospora chalcea DSM 43026T (96.4 %). However, the 16S rRNA and gyrB gene sequence-based phylogeny and phenotypic characteristics provided support to distinguish strain A38T as a novel species. On the basis of the results presented here, we propose to classify strain A38T (=LMG 30467T=CECT 30034T) as the type strain of the novel species Micromonospora fluminis sp. nov.

A Gram-positive, spore-forming, rod-shaped bacterium, designated J1T was isolated from deep-sea mud collected from the South China Sea and subjected to polyphasic taxonomic investigation. Phylogenetic analysis based on 16S rRNA gene sequences revealed that J1T clustered with the type strains of Amphibacillus cookii , Amphibacillus sediminis and Amphibacillus jilinensis and exhibited a range of similarity of 93.9–97.0 % to members of the genus Amphibacillus . The DNA G+C content was 36.7 mol%. Chemotaxonomic analysis showed no quinones, and the cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid for strain J1T. The major cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. Strain J1T was positive for catalase activity and negative for oxidase activity. On the basis of phylogenetic position and phenotypic properties, strain J1T represents a novel species of the genus Amphibacillus and the name Amphibacillus marinus sp. nov. is proposed. The type strain is J1T ( = CGMCC 1.10434T = JCM 17099T).

A second novel clinical actinobacterial strain, designated IFM 10348T, was isolated from the sputum of the same Japanese patient with bacterial pneumonia from whom the type strain of Gordonia araii had been isolated. The strains differed in phylogenetic position and drug-resistance profiles. The taxonomic position of strain IFM 10348T was clarified by phenotypic, chemotaxonomic and phylogenetic studies. Phylogenetic analyses based on 16S rRNA gene sequences clearly demonstrated that strain IFM 10348T occupied a distinct clade within the genus Gordonia and was related closely to Gordonia malaquae DSM 45064T and Gordonia hirsuta DSM 44140T (97.3 and 97.1 % similarities, respectively). Strain IFM 10348T was also clearly differentiated from G. malaquae DSM 45064T and G. hirsuta DSM 44140T based on gyrB and secA1 gene sequence similarity values. Strain IFM 10348T had MK-9(H2) as the predominant menaquonine, contained meso-diaminopimelic acid, arabinose, galactose and glucosamine as cell-wall components, and contained C18 : 1ω9c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 as the major cellular fatty acids. Mycolic acids were present. The DNA G+C content of strain IFM 10348T was 68.0 mol%. DNA–DNA relatedness data coupled with the combination of genotypic and phenotypic data indicated that strain IFM 10348T represents a novel species of the genus Gordonia , for which the name Gordonia iterans sp. nov. is proposed. The type strain is IFM 10348T ( = CCTCC M2011245T = NCCB 100436T).

Two novel bacterial strains, GH2-4T and GH2-5, were isolated from mangrove soil near the seashore of Weno island in Chuuk state, Micronesia, and were characterized by a polyphasic approach. The two strains were strictly aerobic, Gram-staining-positive, motile, endospore-forming rods that were catalase- and oxidase-positive. Colonies were circular, convex, stringy and transparent yellowish (GH2-4T) or opaque whitish (GH2-5). The 16S rRNA gene sequences of the two isolates were identical. The most closely related strains in terms of 16S rRNA gene sequence similarity were Bacillus kochii WCC 4582T, B. horneckiae DSM 23495T, B. azotoformans LMG 9581T, B. cohnii DSM 6307T and B. halmapalus DSM 8723T (95.6, 95.4, 95.4, 95.2 and 95.2 % similarity, respectively). The partial groEL sequence of strain GH2-4T was identical to that of strain GH2-5 and showed <85 % similarity to those of the most closely related strains. The isolates grew at pH 5–12 (optimal growth at pH 9), at 10–40 °C (optimum 30–35 °C) and at 0–9 % (w/v) NaCl (optimum 1–3 % NaCl). The cell-wall peptidoglycan of strains GH2-4T and GH2-5 contained meso-diaminopimelic acid and cell-wall hydrolysates contained ribose as a major sugar. The DNA G+C content was 36 mol%, and DNA–DNA relatedness between the isolates and five related reference strains was 20–24 %. Strain GH2-4T exhibited 81 % DNA–DNA relatedness with strain GH2-5. The major cellular fatty acids of both strains were iso-C15 : 0, iso-C16 : 0, iso-C14 : 0 and anteiso-C15 : 0 and the predominant menaquinone was MK-7. On the basis of the evidence from this polyphasic study, strains GH2-4T and GH2-5 ( = KCTC 33143 = JCM 18995 = DSM 27084) represent a novel species of the genus Bacillus , for which the name Bacillus solimangrovi sp. nov. is proposed; the type strain is GH2-4T ( = KCTC 33142T = JCM 18994T = DSM 27083T).

A Gram-stain-positive, aerobic actinomycete, designated strain BMP B8144T, was isolated from desert soil, in Xinjiang province, northwest China. The isolate produced scanty aerial mycelium and fragmented substrate mycelium on most tested media. Cell-wall hydrolysates contained meso-diaminopimelic acid, galactose and mannose. The diagnostic phospholipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylhydroxylethanolamine, phosphatidylinositol, and phosphatidylinositol mannosides. The major fatty acids included iso-C16 : 0, C17 : 1 ω8c and iso-C15 : 0. The predominant menaquinones were MK-9(H4) and MK-10(H4). The DNA G+C content was 70.4 mol% (genome). Based on the 16S rRNA gene sequence analysis on EzBioCloud server, strain BMP B8144T showed the closest similarities to Saccharothrix lopnurensis YIM LPA2hT (98.9 %) and ‘ Saccharothrix yanglingensis ’ Hhs.015 (98.6 %). However, it can be distinguished from the closest strains based on the low levels of DNA–DNA relatedness (59.3±1.8 and 47.9±2.3 %, respectively). A combination of morphological, chemotaxonomic and phylogenetic characteristics, strain BMP B8144T represents a novel species of the genus Saccharothrix , for which the name Saccharothrix deserti sp. nov. is proposed. The type strain is BMP B8144T (=CGMCC 4.7490T=KCTC 49001T).

A rod-shaped, motile, facultatively anaerobic and moderately halotolerant plant-growth-promoting actinobacterial strain, designated NCCP-11T, was isolated from paddy grains. To delineate its taxonomic position, the strain was subjected to a polyphasic characterization. Cells of strain NCCP-11T grew at 10–37 °C (optimum 28–32 °C), at pH 6–9 (optimum pH 7) and in 0–12 % (w/v) NaCl (optimum 1–2 %) in broth medium. Based on 16S rRNA gene sequence analysis, strain NCCP-11T showed highest similarity to the type strains of Cellulomonas hominis (98.99 %) and Cellulomonas denverensis (98.09 %) and less than 97 % with other closely related taxa. The chemotaxonomic data [major menaquinone: MK-9(H4); cell-wall peptidoglycan: type A4β; major fatty acids: anteiso-C15 : 0, C16 : 0, C14 : 0 and anteiso-C17 : 0; major polar lipids: diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositolmannosides and two unknown polar lipids] also supported the affiliation of strain NCCP-11T to the genus Cellulomonas . The level of DNA–DNA relatedness between strain NCCP-11T and the two type strains mentioned above was less than 42.7 %. On the basis of DNA–DNA relatedness, physiological and biochemical characteristics and phylogenetic position, strain NCCP-11T can be differentiated from species of the genus Cellulomonas with validly published names and thus represents a novel species, for which the name Cellulomonas pakistanensis sp. nov. is proposed. The type strain is NCCP-11T ( = DSM 24792T = JCM 18755T = KCTC 19798T).
