Abstract Strain WGZ8T was isolated from a soil sample of Puerh tea garden in Puer city, Southwest China. The isolate was rod-shaped, Gram-stain negative, aerobic, non-motile. Growth occurred within 0-3.0% (w/v) NaCl (optimal concentration, 0-1.0%), pH 5.0-11.0 (optimal pH, 7.0) and 10-40°C (optimal temperature, 28°C). 16S rRNA gene sequences based phylogenetic and phylogenomic analysis revealed that WGZ8T belonged to the genus Microvirga. Its major cellular fatty acids were C19:0 cyclo ω8c, C16:0, C18:1ω7c and/or C18:1ω6c. The profile of polar lipids included phosphatidyldimethylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol and phosphatidyl-glycerol. The only respiratory quinone was detected as ubiquinone 10 (Q-10). The genome size of strain WGZ8T was 5.17MB, and the content of DNA G+C was 61%. Based on the results of digital DNA-DNA hybridization and phenotypic results, strain WGZ8T could be concluded as a novel species of the genus Microvirga, for which the name Microvirga puerhi sp. nov. is proposed. The type strain is WGZ8T (=CGMCC 1.19171T=JCM XXXXT).

A taxonomic study was carried out on strain YN3T, which was isolated from a seaweed sample taken from the coast of Weihai, China. The bacterium was Gram-stain-negative, rod-shaped, and could grow at pH 5.0–10.0 and 4–32 °C in the presence of 0–9.0 % (w/v) NaCl. Strain YN3T was positive for the hydrolysis of polysaccharides, such as agar, starch and xylan. The predominant respiratory quinone was ubiquinone-8. The major fatty acids were C16 : 1ω7c and/or iso-C15 : 0 2-OH, C16 : 0 and C18 : 1ω7c. The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, and two unidentified glycolipids. The genomic DNA G+C content was 49.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YN3T should be assigned to the genus Gilvimarinus . ‘Gilvimarinus agarilyticus’ KCTC 23325 and Gilvimarinus chinensis QM42T had the closest phylogenetic relationship to strain YN3T, and showed 97.9 % and 95.8 % sequence similarities, respectively. On the basis of phenotypic, chemotaxonomic and genotypic data and DNA–DNA hybridization studies, we propose that strain YN3T represents a novel species of the genus Gilvimarinus , for which the name Gilvimarinus polysaccharolyticus sp. nov. is proposed. The type strain is YN3T ( = KCTC 32438T = JCM 19198T). An emended description of the genus Gilvimarinus is also presented.

A bacterial strain (DB5T), with polysaccharide-degrading activities, was isolated from garden soil in Daejeon, Republic of Korea. The cells were Gram-positive, aerobic or facultatively anaerobic, non-motile straight rods. Phylogenetic analysis based on 16S rRNA gene sequences showed that this strain belongs to the genus Cellulomonas and that it is most closely related to Cellulomonas xylanilytica LMG 21723T and Cellulomonas humilata ATCC 25174T (98·0 and 97·9 % similarity, respectively). Chemotaxonomic data also supported the classification of strain DB5T in the genus Cellulomonas, i.e. l-ornithine as the cell-wall diamino acid, anteiso-C15 : 0 and iso-C15 : 0 as the major fatty acids, MK-9(H4) as the predominant menaquinone and the presence of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol mannosides in the polar lipid profile. The results of DNA–DNA hybridization in combination with chemotaxonomic and physiological data demonstrated that strain DB5T (=KCTC 19081T=NBRC 100819T) should be classified as the type strain of a novel species within the genus Cellulomonas, for which the name Cellulomonas terrae sp. nov. is proposed.

A novel actinomycete, designated strain A31T, was isolated from the surface of weathered biotite in Susong, Anhui Province, China. The organism grew optimally at 30 °C, at pH 8.0 and with 1 % (w/v) NaCl. Strain A31T had A3α as the cell-wall peptidoglycan type and galactose, mannose and rhamnose as whole-cell sugars. Anteiso-C15 : 0 and anteiso-C17 : 0 were the major cellular fatty acids and MK-9(H2) was the predominant respiratory quinone. In addition, the total polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylmonomethylethanolamine and four glycolipids. The genomic DNA G+C content of strain A31T was 70.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain A31T was related most closely to Sinomonas albida LC13T (98.3 % similarity), Sinomonas atrocyanea DSM 20127T (98.2 %), Sinomonas soli CW 59T (98.1 %), Sinomonas flava CW 108T (97.8 %), ‘Sinomonas mesophila’ MPKL 26 (97.3 %), Sinomonas echigonensis LC10T (97.1 %) and ‘ Sinomonas notoginsengisoli ’ SYP-B575 (96.7 %). DNA–DNA hybridization studies with the new isolate showed relatedness values of 16.0–56.6 % with its six closest neighbours. Based on phenotypic, chemotaxonomic and phylogenetic analysis, strain A31T represents a novel species of the genus Sinomonas , for which the name Sinomonas susongensis sp. nov. is proposed.

Twelve Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and motile strains (CY7WT, CY18WT, CY22WT, FT31WT, FT137WT, FT147WT, BYS50W, BYS107WT, LFS511WT, LX15WT, LX22WT and NL8WT) were isolated from streams in China. Comparisons based on 16S rRNA gene sequences indicated that these strains take species of genus Undibacterium as close neighbours. The reconstructed phylogenetic and phylogenomic trees also showed that these strains cluster with species of genus Undibacterium together. The genome G+C contents of these strains were in the range of 45.3 to 53.3 mol%. The calculated pairwise OrthoANIu values and digital DNA–DNA hybridization values among these strains and related strains were in the range of 70.4 to 94.1% and 19.3 to 55.3% except that the values between strains CY7WT and BYS50W were 99.0 and 91.8 %, respectively. Q-8 was their predominant respiratory quinone. C16 : 1  ω7c and C16 : 0 were their major fatty acids. Their polar lipids profiles were similar, including phosphatidylglycerol, phosphatidylethanolamine, one unidentified phospholipid and two kinds of unidentified aminolipids. Combining polyphasic taxonomic characteristics and phylogenetic relationships, twelve strains should represent eleven independent novel species of genus Undibacterium , for which the names Undibacterium baiyunense sp. nov. (type strain BYS107WT=GDMCC 1.2453T=KCTC 82653T), Undibacterium curvum sp. nov. (type strain CY22WT=GDMCC 1.1906T=KACC 21951T), Undibacterium fentianense sp. nov. (type strain FT137WT=GDMCC 1.2456T=KCTC 82656T), Undibacterium flavidum sp. nov. (type strain LX15WT=GDMCC 1.1910T=JCM 34286T), Undibacterium griseum sp. nov. (type strain FT31WT=GDMCC 1.1908T=KACC 21953T), Undibacterium hunanense sp. nov. (type strain CY18WT=GDMCC 1.1904T=KACC 21949T), Undibacterium luofuense sp. nov. (type strain LFS511WT=GDMCC 1.2458T=KCTC 82658T), Undibacterium nitidum sp. nov. (type strain LX22WT=GDMCC 1.1912T=KACC 21957T), Undibacterium rivi sp. nov.

A novel strain, C-138T, belonging to the genus Corynebacterium was isolated from a severe thigh liposarcoma infection and its differentiation from Corynebacterium xerosis and Corynebacterium freneyi is described. Analysis of 16S rRNA gene sequences, rpoB sequences and the PCR profile of the 16S–23S spacer regions was not conclusive enough to differentiate strain C-138T from C. xerosis and C. freneyi. However, according to DNA–DNA hybridization data, strain C-138T constitutes a member of a distinct novel species. It can be differentiated from strains of C. xerosis and C. freneyi by colony morphology, the absence of α-glucosidase and some biochemical characteristics such as glucose fermentation at 42 °C and carbon assimilation substrates. The name Corynebacterium hansenii sp. nov. is proposed for this novel species; the type strain is C-138T (=CIP 108444T=CCUG 53252T).

We isolated a strain coded Esc2AmT during a study focused on the microbial diversity of adult specimens of the bark beetle Hylesinus fraxini. Its 16S rRNA gene sequence had 99.4 % similarity with respect to its closest relative, Pseudomonas rhizosphaerae IH5T. The analysis of partial sequences of the housekeeping genes rpoB, rpoD and gyrB confirmed that strain Esc2AmT formed a cluster with P. rhizosphaerae IH5T clearly separated from the remaining species of the genus Pseudomonas. Strain Esc2AmT had polar flagella and could grow at temperatures from 4 °C to 30 °C. The respiratory quinone was Q9 and the main fatty acids were C16 : 0, C18 : 1ω7c and/or C18 : 1ω6c in summed feature 8 and C16 : 1ω7c and/or C16 : 1ω6c in summed feature 3. DNA–DNA hybridization results showed 51 % relatedness with respect to P. rhizosphaerae IH5T. Oxidase, catalase and urease-positive, the arginine dihydrolase system was present but nitrate reduction and β-galactosidase production were negative. Aesculin hydrolysis was positive. Based on the results from the genotypic, phenotypic and chemotaxonomic analyses, we propose the classification of strain Esc2AmT as representing a novel species of the genus Pseudomonas, for which we propose the name Pseudomonas coleopterorum sp. nov. The type strain is Esc2AmT ( = LMG 28558T = CECT 8695T).

A yellow-pigmented, Gram-stain-negative and facultatively anaerobic bacterium, designated FB218T, was isolated from a sediment sample collected from a sea cucumber culture pond in Rongcheng, China (36° 54′ 36″ N 122° 14′ 34″ E). Cells of strain FB218T were slender, gliding, catalase-positive and oxidase-negative. Optimal growth occurred at 30 °C, pH 6.5–7.0 and in medium containing 2–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain FB218T belonged to the genus Carboxylicivirga, family Marinilabiliaceae. The predominant fatty acids were iso-C15 : 0 and anteiso-C15 : 0. MK-7 was the main respiratory quinone. The major polar lipids of strain FB218T were two unidentified lipids and a phospholipid. The genomic DNA G+C content was 40.0 mol%. Based on the distinct phylogenetic position and the combination of physiological and phenotypic characteristics, strain FB218T represents a novel species of the genus Carboxylicivirga, for which the name Carboxylicivirga linearis sp. nov. is proposed. The type strain is FB218T ( = KCTC 42254T = MCCC 1H00106T). An emended description of the genus Carboxylicivirga is also provided.

A Gram-stain-negative, rod-shaped, aerobic, non-flagellated, chemoheterotrophic bacterium, designated IMCC14385T, was isolated from surface seawater of the East Sea, Republic of Korea. The 16S rRNA gene sequence analysis indicated that IMCC14385T represented a member of the genus Halioglobus sharing 94.6–97.8 % similarities with species of the genus. Whole-genome sequencing of IMCC14385T revealed a genome size of 4.3 Mbp and DNA G+C content of 56.7 mol%. The genome of IMCC14385T shared an average nucleotide identity of 76.6 % and digital DNA–DNA hybridization value of 21.6 % with the genome of Halioglobus japonicus KCTC 23429T. The genome encoded the complete poly-β-hydroxybutyrate biosynthesis pathway. The strain contained summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and C17 : 1 ω8c as the predominant cellular fatty acids as well as ubiquinone-8 (Q-8) as the respiratory quinone. The polar lipids detected in the strain were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, five unidentified phospholipids, an unidentified aminolipid, an unidentified aminophospholipid and four unidentified lipids. On the basis of taxonomic data obtained in this study, it is suggested that IMCC14385T represents a novel species of the genus Halioglobus , for which the name Halioglobus maricola sp. nov. is proposed. The type strain is IMCC14385T (=KCTC 72520T=NBRC 114072T).
