A Gram-staining-positive, rod-shaped, aerobic bacterium, designated strain LAM0410T, was isolated from an oil-contaminated water sample from the Dagang Oilfield, PR China. The temperature and pH ranges for growth were 4 °C to 50 °C and pH 4.4 to pH 12.0, respectively. The strain did not need NaCl for growth, but could tolerate a concentration of up to 12 % (w/v). Cell wall hydrolysates from the isolate showed that the diamino acid was ornithine. The cell wall sugars contained ribose and galactose. The glycan moiety of the cell wall contained N-glycolyl residues. The major respiratory quinones were MK-10, MK-11 and MK-12. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and nine unknown glycolipids. The major fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. 16S rRNA gene sequence analysis indicated that the isolate belonged to the genus Microbacterium and was closely related to Microbacterium sediminis MCCC 1A06153T and Microbacterium murale DSM 22178T with 97.5 % and 97.4 % sequence similarities, respectively; while the DNA–DNA hybridization values were 33.1±3.4 % and 21.8±1.6 %, respectively. The DNA G+C content was 67.4 mol%, as determined by the T m method. Based on its phenotypic and genotypic properties, strain LAM0410T represents a novel species of the genus Microbacterium , for which the name Microbacterium petrolearium sp. nov. is proposed; the type strain is LAM0410T ( = ACCC 00719T = JCM 19612T).

Strain SJQ9T, an aerobic bacterium isolated from a soil sample collected in Shanghai, PR China, was characterized using a polyphasic approach. It grew optimally at pH 7.0, 30–35 °C and in the presence of 1 % (w/v) NaCl. A comparative analysis of 16S rRNA gene sequences showed that strain SJQ9T fell within the genus Aquabacterium . The closest phylogenetic relatives of strain SJQ9T were Aquabacterium citratiphilum DSM 11900T (98.6 % sequence similarity) and Aquabacterium commune DSM 11901T (96.4 %). Cells of the strain were Gram-stain-negative, motile, non-spore-forming, rod-shaped and positive for oxidase activity and negative for catalase. The chemotaxonomic properties of strain SJQ9T were consistent with those of the genus Aquabacterium : the major fatty acid was summed feature 3 (C16 : 1  ω6c and/or C16 : 1  ω7c). The isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content was 65.7 mol%. Strain SH9T exhibited a DNA–DNA relatedness level of 34±2 % with A. citratiphilum DSM 11900T and 28±3 % with A. commune DSM 11901T. Based on the obtained data, strain SJQ9T represents a novel species of the genus Aquabacterium , for which the name Aquabacterium soli sp. nov. is proposed. The type strain is SJQ9T (=JCM 33106T=CCTCC AB 2018284T).

Degrading Bacterium

A Gram-staining-negative, facultatively aerobic bacterium, designated SM-2T, was isolated from a sea-tidal flat of Yellow Sea, South Korea. Cells were catalase- and oxidase-positive motile rods with a single polar flagellum. Growth of strain SM-2T was observed at 10–37 °C (optimum, 25–30 °C), at pH 5.5–8.5 (optimum, pH 7.0–7.5) and in the presence of 0–11 % (w/v) NaCl (optimum, 2 %). Strain SM-2T contained ubiquinone-8 (Q-8) as the sole isoprenoid quinone and C17 : 1ω8c, summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), C17 : 0 and C18 : 1ω7c as the major fatty acids. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified lipid were identified as the major cellular polar lipids. The G+C content of the genomic DNA was 52.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SM-2T formed a tight phyletic lineage with Zhongshania antarctica ZS5-23T, Zhongshania guokunii ZS6-22T and Spongiibacter borealis CL-AS9T, but that S. borealis CL-AS9T was distinct from other species of the genus Spongiibacter . Based on 16S rRNA gene sequence similarities, strain SM-2T was most closely related to S. borealis CL-AS9T, Z. antarctica ZS5-23T and Z. guokunii ZS6-22T, with similarities of 99.5 %, 98.9 % and 98.7 %, respectively, but the DNA–DNA hybridization values among these species were clearly lower than 70 %. On the basis of chemotaxonomic data and molecular properties, we propose strain SM-2T represents a novel species of the genus Zhongshania with the name Zhongshania aliphaticivorans sp. nov. (type strain SM-2T = KACC 18120T = JCM 30138T). We also propose the transfer of Spongiibacter borealis Jang et al. 2011 to the genus Zhongshania as Zhongshania borealis comb. nov. (type strain CL-AS9T = KCCM 90094T = JCM 17304T).

A novel Gram-staining-positive, aerobic bacterium, designed DCY80T, was isolated from soil of a ginseng field in the Republic of Korea. 16S rRNA gene sequence analysis revealed that strain DCY80T belonged to the genus Brachybacterium (95.8–98.2 % similarity) and was most closely related to Brachybacterium faecium DSM 4810T (98.2 %). Colonies were circular, entire, low-convex, opaque and 0.5–1.0 mm in diameter after growth for 2 days on TSA at 30 °C. Growth occurred at 4–34 °C (optimum, 25 °C), at pH 5.0–10.0 (optimum, pH 6.5–7.0) and in the presence of 0–7.0 % NaCl. Strain DCY80T produced siderophores and was sensitive to penicillin G, erythromycin, cefazolin, oleandomycin, ceftazidime, vancomycin, tetracycline, novobiocin, carbamicillin, rifampicin and neomycin. The DNA G+C content was 71.0 mol%. Levels of DNA–DNA relatedness between strain DCY80T and B. faecium DSM 4810T, B. paraconglomeratum KCTC 9916T, B. saurashtrense DSM 23186T and B. conglomeratum KCTC 9915T were 46.9±0.5, 28.9±0.6, 20.4±0.9 and 17.3±0.4 %, respectively. The cell-wall peptidoglycan of strain DCY80T contained meso-diaminopimelic acid as the diagnostic diamino acid. The menaquinones were MK-7 (85.8 %) and MK-8 (14.2 %). The major cellular fatty acids were anteiso-C15 : 0 (69.1 %) and anteiso-C17 : 0 (12.2 %). Phosphatidylglycerol, diphosphatidylglycerol, an unidentified glycolipid, two unidentified phospholipids and five unidentified polar lipids were found. On the basis of our phenotypic and genotypic analyses, strain DCY80T represents a novel species of the genus Brachybacterium , for which the name Brachybacterium ginsengisoli sp. nov. is proposed (type strain DCY80T = KCTC 29226T = JCM 19356T).

A Gram-stain-positive, spore-forming, obligately anaerobic bacterium, designated LAM201T, was isolated from sediment samples from an alkaline-saline lake located in Daqing oilfield, Daqing City, PR China. Cells of strain LAM201T were non-motile and straight or spiral rod-shapes. Strain LAM201T was able to utilize glucose, fructose, maltose, trehalose and sorbitol as the sole carbon source. Acetic acid, ethanol, iso-butanoic acid and iso-valeric acid were the main products of glucose fermentation. The major fatty acids of LAM201T were C16 : 0 (26.7 %) and C18 : 0 (11.2 %). The main polar lipids were four unknown glycolipids and five unknown phospholipids. The predominant cell-wall sugars were ribose and galactose. The cell-wall peptidoglycan of strain LAM201T contained alanine, glycine, glutamic acid and aspartic acid. Sodium sulfite was used as the electron acceptor. The G+C content of the genomic DNA was 32±0.8 mol%, as determined by the T m method. Analysis of the 16S rRNA gene sequence indicated that the isolate belonged to the genus Romboutsia and was most closely related to Romboutsia lituseburensis DSM 797T and Romboutsia ilealis CRIBT with 97.3 % and 97.2 % similarities, respectively. The DNA–DNA hybridization values between strain LAM201T and the two reference strains were 37 % and 31 %, respectively. On the basis of its phenotypic, phylogenetic and chemotaxonomic characteristics, strain LAM201T is suggested to represent a novel species within the genus Romboutsia , for which the name Romboutsia sedimentorum sp. nov. is proposed. The type strain is LAM201T ( = ACCC 00717T = JCM 19607T).

A novel Gram-staining-negative, catalase- and oxidase-positive, facultatively anaerobic and rod-shaped motile bacterial strain, designated as ZWAL4003T, was isolated from mangrove sediments of the Zini Mangrove Forest, Zhangzhou City, PR China. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that ZWAL4003T was grouped into a separated branch with Vibrio plantisponsor MSSRF60T (97.38% nucleotide sequence identity) and Vibrio diazotrophicus NBRC 103148T (97.27%). The major cellular fatty acids were C14 : 0 (12.6%), C16 : 0 (17.6%), and summed feature 3 (C16 : 1ω6c /C16 : 1 ω7c, 45.6%). Its genome had a length of 4650556 bp with 42.8% DNA G+C content, and contained genes involved in the biosynthesis of bacteriocin, β-lactone, resorcinol, N-acyl amino acid, and arylpolyene. The in silico DNA–DNA hybridization and average nucleotide identity values for whole-genome sequence comparisons between ZWAL4003T and V. plantisponsor LMG 24470T were clearly below the thresholds used for the delineation of a novel species. The morphological and chemotaxonomic characteristics and the genotypic data of ZWAL4003T indicated that it represented a novel species of the genus Vibrio . Its proposed name is Vibrio ziniensis sp. nov., and the type strain is ZWAL4003T (=KCTC 72971T=MCCC 1A17474T).

Taxonomic Approach

A novel actinobacterium, strain A8036T, isolated from soil, was investigated by using a polyphasic taxonomic approach. The organism formed extensively branched substrate hyphae that generated spiral chains of spores with irregular surfaces. The cell wall contained meso-diaminopimelic acid (type III) and cell-wall sugars were glucose, madurose, mannose and ribose. The predominant menaquinones were MK-9(H6) and MK-9(H4). The phospholipids were diphosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major cellular fatty acids were iso-C16 : 0, C17 : 1 cis9, C16 : 0, C15 : 0 and 10-methyl C17 : 0. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of strain A8036T were Actinomadura meyerae DSM 44715T (99.23 % similarity), Actinomadura bangladeshensis DSM 45347T (98.9 %) and Actinomadura chokoriensis DSM 45346T (98.3 %). However, DNA–DNA relatedness and phenotypic data demonstrated that strain A8036T could be clearly distinguished from the type strains of all closely related Actinomadura species. Strain A8036T is therefore considered to represent a novel species of the genus Actinomadura , for which the name Actinomadura geliboluensis sp. nov. is proposed. The type strain is A8036T ( = DSM 45508T = KCTC 19868T).

A Gram-staining-negative bacterium, strain TS-T86T, was isolated from Lake Tuosu, a saline lake (salinity 5.4 %, w/w) in Qaidam basin, China. Its taxonomic position was determined by using a polyphasic approach. Strain TS-T86T was strictly heterotrophic, aerobic and catalase- and oxidase-positive. Cells were non-spore-forming, non-motile rods, 0.4–0.6 µm wide and 1.2–2.3 µm long. Growth was observed in the presence of 0–9.0 % (w/v) NaCl (optimum, 2.0 %), at 4–35 °C (optimum, 25 °C) and at pH 7.0–10.5 (optimum, pH 8.5–9.0). Strain TS-T86T contained MK-7 as the predominant respiratory quinone. The major fatty acids (>10 %) were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 1ω9c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipids consisted of phosphatidylethanolamine, an unknown phospholipid, six unidentified aminolipids and two uncharacterized lipids. The DNA G+C content was 35 mol% (T m). Phylogenetic trees based on 16S rRNA gene sequences showed that strain TS-T86T was associated with the genus Belliella , and showed the highest sequence similarity to Belliella baltica BA134T (98.5 %) and then to Belliella kenyensis No.164T (95.7 %) and Belliella pelovolcani CC-SAL-25T (95.3 %). DNA–DNA relatedness of strain TS-T86T to Belliella baltica DSM 15883T was 32±3 %. It is concluded that strain TS-T86T represents a novel species of the genus Belliella , for which the name Belliella aquatica sp. nov. is proposed. The type strain is TS-T86T ( = CGMCC 1.12479T = JCM 19468T).

A novel actinobacterium, designated strain NEAU-351T, was isolated from cow dung collected from Shangzhi, Heilongjiang Province, northeast PR China and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-351T belonged to the genus Nocardia , with the highest similarity (98.96 %) to Nocardia takedensis DSM 44801T and less than 98.0 % identity with other type strains of the genus Nocardia . The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The major menaquinone was observed to contain MK-8(H4, ω-cycl) (78.2 %). The fatty acid profile mainly consisted of C16 : 0, C18 : 1  ω9c and 10-methyl C18 : 0. Mycolic acids were present. The genomic DNA G+C content of strain NEAU-351T was 68.1 mol%. In addition, the average nucleotide identity values between strain NEAU-351T and its reference strains, Nocardia takedensis DSM 44801T and Nocardia arizonensis NBRC 108935T, were found to be 81.4 and 82.9 %, respectively, and the level of digital DNA–DNA hybridization between them were 24.8 % (22.5–27.3 %) and 26.3 % (24–28.8 %), respectively. Here we report on the taxonomic characterization and classification of the isolate and propose that strain NEAU-351T represents a new species of the genus Nocardia , for which the name Nocardia bovistercoris is proposed. The type strain is NEAU-351T (=CCTCC AA 2019090T=DSM 110681T).

Strain L22-9T, a Gram-stain-negative and rod-shaped bacterium, motile by one polar flagellum, was isolated from cornfield soil in Bijie, Guizhou Province, PR China. Based on 16S rRNA gene sequences, it was identified as a Pseudomonas species. Multilocus sequence analysis of concatenated 16S rRNA, gyrB, rpoB and rpoD gene sequences showed that strain L22-9T formed a clearly separated branch, located in a cluster together with Pseudomonas brassicacearum LMG 21623T, Pseudomonas kilonensis DSM 13647T and Pseudomonas thivervalensis DSM 13194T. Whole-genome comparisons based on average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) confirmed that strain L22-9T should be classified as a novel species. It was most closely related to P. kilonensis DSM 13647T with ANI and dDDH values of 91.87 and 46.3 %, respectively. Phenotypic features that can distinguish strain L22-9T from P. kilonensis DSM 13647T are the assimilation ability of N-acetyl-d-glucosamine, poor activity of arginine dihydrolase and failure to ferment ribose and d-fucose. The predominant cellular fatty acids of strain L22-9T are C16 : 0, summed feature 3 (C16 : 1 ω6c and/or C16 : 1 ω7c) and summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c). The respiratory quinones consist of Q-9 and Q-8. The polar lipids are diphosphatidylglycerol, phosphatidylethanolamine, two unidentified phosphoglycolipids, two unidentified aminophospholipids and an unidentified glycolipid. Based on the evidence, we conclude that strain L22-9T represents a novel species, for which the name Pseudomonas bijieensis sp. nov. is proposed. The type strain is L22-9T (=CGMCC 1.18528T=LMG 31948T), with a DNA G+C content of 60.85 mol%.

Four Gram-stain-positive, catalase-negative, non-spore-forming, rod-shaped bacterial strains (zg-325T, zg329, dk561T and dk752) were isolated from the respiratory tract of marmot (Marmota himalayana) and the faeces of Tibetan gazelle (Procapra picticaudata) from the Qinghai-Tibet Plateau of PR China. The results of 16S rRNA gene sequence-based phylogenetic analyses indicated that strains zg-325T and dk561T represent members of the genus Actinomyces , most similar to Actinomyces denticolens DSM 20671T and Actinomyces ruminicola B71T, respectively. The DNA G+C contents of strains zg-325T and dk561T were 71.6 and 69.3 mol%, respectively. The digital DNA–DNA hybridization values of strains zg-325T and dk561T with their most closely related species were below the 70 % threshold for species demarcation. The four strains grew best at 35 °C in air containing 5 % CO2 on brain heart infusion (BHI) agar with 5 % sheep blood. All four strains had C18:1ω9c and C16:0 as the major cellular fatty acids. MK-8 and MK-9 were the major menaquinones in zg-325T while MK-10 was predominant in dk561T. The major polar lipids included diphosphatidylglycerol and phosphatidylinositol. On the basis of several lines of evidence from phenotypic and phylogenetic analyses, zg-325T and dk561T represent novel species of the genus Actinomyces , for which the name Actinomyces marmotae sp. nov. and Actinomyces procaprae sp. nov. are proposed. The type strains are zg-325T (=GDMCC 1.1724T=JCM 34091T) and dk561T (=CGMCC 4.7566T=JCM 33484T). We also propose, on the basis of the phylogenetic results herein, the reclassification of Actinomyces liubingyangii and Actinomyces tangfeifanii as Boudabousia liubingyangii comb. nov. and Boudabousia tangfeifanii comb. nov., respectively.
