A novel Gram-stain-negative, aerobic, orange-pigmented, non-flagellated, gliding, rod-shaped bacterium, designated strain SM1354T was isolated from surface seawater of the Atlantic Ocean. The strain hydrolysed gelatin and DNA but did not reduce nitrate. It grew at 4–40 °C and with 0.5–11 % (w/v) NaCl. Phylogenetic analysis of the 16S rRNA gene sequences revealed that strain SM1354T belonged to the genus Marivirga with 96.0–96.2 % sequence similarities to known species of the genus Marivirga . The major fatty acids of strain SM1354T were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 03-OH and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 02-OH). Polar lipids of strain SM1354T included phosphatidylethanolamine, three unidentified lipids and one unidentified aminolipid and aminophospholipid. The major respiratory quinone of strain SM1354T was menaquinone 7 (MK-7). The genomic DNA G+C content of strain SM1354T was 33.9±0.4 mol%. On the basis of the results of the polyphasic characterization in this study, it is proposed that strain SM1354T represents a novel species of the genus Marivirga , namely Marivirga atlantica sp. nov. The type strain of Marivirga atlantica is SM1354T ( = CCTCC AB 2014242T = JCM 30305T). An emended description of the genus Marivirga is also proposed.

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.

The taxonomic position of strain MSSRFBL1T, isolated from chickpea rhizosphere soil from Kannivadi, India, was determined. Strain MSSRFBL1T formed bluish black colonies, stained Gram-negative and was motile, aerobic, capable of fixing dinitrogen, oxidase-negative and catalase-positive. Q-10 was the major respiratory quinone. Major fatty acids of strain MSSRFBL1T were C18 : 1ω7c and C19 : 0cycloω8c. Minor amounts of C18 : 0, C12 : 0, C14 : 0 3-OH, C18 : 0 3-OH, C16 : 0, C16 : 1ω6c/C16 : 1ω7c, C17 : 0 3-OH and C20 : 1ω7c were also present. Polar lipids included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylcholine and two unidentified glycolipids. Bacteriohopane derivatives (BHD1 and 2), diplopterol, diploptene, bishomohopanediol, adenosylhopane and 2β-methyl bacteriohopanetetrol were the major hopanoids of strain MSSRFBL1T. The genomic DNA G+C content was 71 mol%. EzTaxon-e-based blast analysis of the 16S rRNA gene indicated the highest similarity of strain MSSRFBL1T to Ensifer adhaerens LMG 20216T (97.3 %) and other members of the genus Ensifer (<96.9 %) in the family Rhizobiaceae of the class Alphaproteobacteria . However, phylogenetic analysis based on 16S rRNA, recA, thrC and dnaK gene sequences showed distinct out-grouping from the recognized genera of the family Rhizobiaceae . Based on phenotypic, genotypic and chemotaxonomic characters, strain MSSRFBL1T represents a novel species in a new genus in the family Rhizobiaceae for which the name Ciceribacter lividus gen. nov., sp. nov. is proposed. The type strain of Ciceribacter lividus is MSSRFBL1T ( = DSM 25528T = KCTC 32403T).

A novel biosurfactant-producing strain, designated YW1T, was isolated from agricultural soil. Its taxonomic position was investigated using a polyphasic approach. The cells were short rods, Gram-negative, non-sporulating and motile. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YW1T was a member of the genus Comamonas , and showed highest sequence similarities to Comamonas aquatica LMG 2370T (98.5 %), Comamonas kerstersii LMG 3475T (97.7 %) and Comamonas terrigena LMG 1253T (97.7 %). Furthermore, DNA–DNA hybridization experiments against these three strains gave results that were clearly lower than 70 % DNA–DNA similarity, and consequently confirmed that this new strain does not belong to a previously described species of the genus Comamonas . The major respiratory quinone was ubiquinone-8. The major fatty acids (>5 %) were C16 : 0 (30.1 %), summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c; 25.4 %), summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c; 15.3 %), C17 : 0 cyclo (7.4 %) and C14 : 0 (5.8 %). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, unknown phospholipids and unknown lipids. Based on the phylogenetic analysis, DNA–DNA hybridization, whole-cell fatty acid composition as well as biochemical characteristics, strain YW1T was clearly distinguishable from all species of the genus Comamonas with validly published names and should be classified as a representative of a novel species of the genus Comamonas , for which the name Comamonas jiangduensis sp. nov. is proposed. The type strain is YW1T ( = CCTCC AB 2012033T = KACC 16697T).

Strain AK13T was positive for oxidase, DNase and lipase activities and negative for catalase, gelatinase, ornithine decarboxylase, lysine decarboxylase, nitrate reductase, aesculinase and urease activities. The fatty acids were dominated by iso-C11 : 0, iso-C11 : 0 3-OH, iso-C15 : 0, iso-C16 : 0, iso-C17 : 1ω9c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). Strain AK13T contained Q-8 as the major respiratory quinone and diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, two unidentified aminolipids, one unidentified glycolipid and one unidentified lipid as the polar lipids. The DNA G+C content of strain AK13T was 55.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the type strain of Silanimonas lenta , of the family Xanthomonadaceae (phylum Proteobacteria ), was the closest neighbour of strain AK13T, with 95.2 % sequence similarity. Other members of the family showed sequence similarities <94.4 %. Based on the phenotypic characteristics and phylogenetic inference, strain AK13T is proposed as a member of a novel species of the genus Silanimonas , Silanimonas mangrovi sp. nov.; the type strain is AK13T ( = MTCC 11082T  = DSM 24914T). An emended description of the genus Silanimonas is also provided.

Strain CAU 1294T contained Q-10 as the predominant respiratory quinone. C18 : 1ω7c, C16 : 0 and cyclo-C19 : 0ω8c were the major cellular fatty acids. The polar lipids were composed of phosphatidylethanolamine, phosphatidylmethylethanolamine and two unidentified phospholipids. The DNA G+C content was 56.6 mol%. On the basis of these results, strain CAU 1294T is considered to represent a novel species of the genus Sneathiella , for which the name Sneathiella chungangensis is proposed. The type strain is CAU 1294T ( = KCTC 32476T = CECT 8513T). An emended description of the genus Sneathiella is also proposed.
