A novel strain, designated J221T, was isolated from the intestine of a sea cucumber, Apostichopus japonicus, collected from earthen ponds in Qingdao, China. The strain was Gram-negative, oxidase-positive, aerobic, rod-shaped and motile by means of one to several polar flagella. Growth of strain J221T was observed at temperatures between 10 and 40 °C with optimum growth between 25 and 28 °C. The pH range for growth was 5.0–9.0 with optimum growth at pH 7.5–8.0. The dominant fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c, 29.04 %), C16 : 0 (28.93 %) and C18 : 1ω7c (26.15 %). The major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. Diphosphatidylglycerol, an unknown aminolipid and an unknown aminophospholipid were present in moderate to minor amounts in the polar lipid profile. Strain J221T had Q-8 as the major respiratory quinone. The DNA G+C content of strain J221T was 46.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain J221T is a member of the Gammaproteobacteria . It formed a distinct phyletic line with less than 91 % sequence similarity to any species within previously recognized genera. On the basis of this polyphasic taxonomic study, strain J221T should be classified as a representative of a novel species of a new genus, for which the name Neiella marina gen. nov., sp. nov. is proposed. The type strain of Neiella marina is J221T ( = CGMCC 1.10130T = NRRL B-51319T).

Two novel strains (HMF3257T and HMF4905T), isolated from freshwater and bark samples, were investigated to determine their relationships within and between species of the genus Spirosoma by using a polyphasic approach. They were aerobic, Gram-stain-negative, non-motile and rod-shaped bacteria. The major fatty acids (>10%) in both strains were identified as summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and C16 : 1 ω5c, while strains HMF3257T and HMF4905T contained a moderately high amount of C16 : 0 and iso-C15 : 0, respectively. The predominant respiratory quinone was MK-7 for both strains. In addition to phosphatidylethanolamine and one unidentified glycolipid, the polar lipid profile of strain HMF3257T consisted of three unidentified aminophospholipids, one unidentified aminolipid and two unidentified polar lipids, and that of strain HMF4905T consisted of one unidentified aminophospholipid, two unidentified aminolipids and three unidentified polar lipids. The DNA G+C contents of strains HMF3257T and HMF4905T were 47.2 and 46.4 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains HMF3257T and HMF4905T are closely related to Spirosoma migulaei 15J9-8T (97.0 % sequence similarity), while sharing 97.4 % sequence similarity with each other. The average nucleotide identity value between strains HMF3257T and HMF4905T was 81.1 %, and the digital DNA–DNA hybridization value between these two strains was 24.4 %. Based on the above data, strains HMF3257T and HMF4905T represent two novel members within the genus Spirosoma , for which the names Spirosoma telluris sp. nov. and Spirosoma arboris sp. nov. are proposed, respectively. The type strain of S. telluris is HMF3257T (=KCTC 62463T=NBRC 112670T) and type strain of S. arboris is HMF4905T (=KCTC 72779T=NBRC 114270T).

A bacterial strain, designated Dd16T, was isolated from a hexachlorocyclohexane (HCH) dumpsite at Lucknow, India. Cells of strain Dd16T were Gram-stain-negative, non-motile, rod-shaped and yellow-pigmented. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain belonged to the genus Sphingomonas in the family Sphingomonadaceae , as it showed highest sequence similarity to Sphingomonas asaccharolytica IFO 15499T (95.36 %), Sphingosinicella vermicomposti YC7378T (95.30), ‘Sphingomonas humi’ PB323 (95.20 %), Sphingomonas sanxanigenens NX02T (95.14 %) and Sphingomonas desiccabilis CP1DT (95.00 %). The major fatty acids were summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) C14 : 0 2-OH, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The polar lipid profile of strain Dd16T also corresponded to those reported for species of the genus Sphingomonas (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, and a sphingoglycolipid), again supporting its identification as a member of the genus Sphingomonas . The predominant respiratory quinone was ubiquinone Q10, and sym-homospermidine was the major polyamine observed. The total DNA G+C content of strain Dd16T was 65.8 mol%. The results obtained on the basis of phenotypic characteristics and phylogenetic analysis and after biochemical and physiological tests, clearly distinguished strain Dd16T from closely related members of the genus Sphingomonas . Thus, strain Dd16T represents a novel species of the genus Sphingomonas for which the name Sphingomonas indica sp. nov. is proposed. The type strain is Dd16T ( = DSM 25434T = CCM 7882T).

The Gram-strain-negative, rod-shaped, facultatively anaerobic, non-motile bacterial strain, designated S1-10T, was isolated from marine sediment. Strain S1-10T grew at 4–42 °C (optimally at 30–35 °C), at pH 7.0–10 (optimally at pH 9) and in the presence of 0.5–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-10T was related to the genus Aequorivita and had highest 16S rRNA gene sequence similarity to Aequorivita viscosa 8-1bT (97.7%). The predominant cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The main respiratory quinone was menaquinone 6 (MK-6). The genomic DNA G+C content of strain S1-10T was 34.6 mol%. The polar lipid profile of strain S1-10T contained phosphatidylethanolamine, two aminolipids, two glycolipids, one phosphoglycolipid and three unidentified polar lipids. In addition, the maximum values of in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI) between strain S1-10T and A. viscosa CGMCC 1.11023T were 15.4 and 75.7 %, respectively. Combined data from phenotypic, phylogenetic, isDDH and ANI analyses demonstrated that strain S1-10T is the representative of a novel species of the genus Aequorivita , for which we propose the name Aequorivita sinensis sp. nov. (type strain S1-10T=CGMCC 1.12579T=JCM 19789T). We also propose that Vitellibacter todarodis and Vitellibacter aquimaris should be transferred into genus Aequorivita and be named Aequorivita todarodis comb. nov. and Aequorivita aquimaris comb. nov., respectively. The type strain of Aequorivita todarodis comb. nov. is MYP2-2T (= KCTC 62141T= NBRC 113025T) and the type strain of Aequorivita aquimaris comb. nov. is D-24T (=KCTC 42708T=DSM 101732T).

A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL02T occupied a distinct phylogenetic position in the genus Novosphingobium and showed the highest sequence similarity with Novosphingobium resinovorum NCIMB 8767T (98.59 %). DNA–DNA relatedness between strain LL02T and its closest phylogenetic neighbours was <70 %, which indicated that strain LL02T represented a novel species of the genus Novosphingobium . The DNA G+C content of strain LL02T was 67.72±0 mol%. The major respiratory quinone was ubiquinone Q-10. The polar lipid profile of the isolate corresponded to those reported for other members of the genus Novosphingobium (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine and sphingoglycolipids), thus supporting its classification in the genus. Spermidine was the major polyamine. The major fatty acids were summed feature 3 (consisting of C16 : 1ω7c and/or C16 : 1ω6c; 40.13 %), summed feature 8 (consisting of C18 : 1ω7c and/or C18 : 1ω6c; 31.09 %) and C14 : 0 2-OH (23.16 %). The results obtained from DNA–DNA hybridization and biochemical and physiological tests clearly distinguished the isolate from its closest phylogenetic neighbours. Thus, strain LL02T represents a novel species of the genus Novosphingobium , for which the name Novosphingobium barchaimii sp. nov. is proposed. The type strain is LL02T ( = CCM 7980T  = DSM 25411T).
