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 yellow-pigmented bacterial strain, designated LL02T, was isolated from hexachlorocyclohexane-contaminated soil from Spolana Neratovice, a former Czech producer of lindane. 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).

A bacterial strain, isolated from a sample of reef-building coral (Isopora palifera) collected off the coast of southern Taiwan, was characterized using a polyphasic taxonomic approach. The strain, designated sw-2T, was Gram-staining-negative, aerobic, rod-shaped and motile, with subpolar flagella, and formed greyish pink colonies. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain sw-2T was most closely related to Roseivivax halodurans Och 239T (97.4 % sequence similarity) and Roseivivax halotolerans Och 210T (96.4 %). The novel strain did not require NaCl for growth and exhibited optimal growth at 35–40 °C, at pH 7.5–8.0 and with 3–7 % (w/v) NaCl. It produced bacteriochlorophyll a under aerobic conditions. Summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c; 63.7 %) predominated in the cellular fatty acid profile. The novel strain’s major respiratory quinone was ubiquinone Q-10 and its genomic DNA G+C content was 68.8 mol%. The polar lipid profile consisted of a mixture of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol, phosphatidyldimethylethanolamine, sulfo-quinovosyl diacylglycerol and three uncharacterized phospholipids. The level of DNA–DNA relatedness between strain sw-2T and Roseivivax halodurans Och 239T was only 15.0 %. The results of physiological and biochemical tests allowed the clear phenotypic differentiation of the novel strain from all established species of the genus Roseivivax . Based on the genotypic, phenotypic and chemotaxonomic data, strain sw-2T represents a novel species in the genus Roseivivax , for which the name Roseivivax isoporae sp. nov. is proposed. The type strain is sw-2T ( = LMG 25204T = BCRC 17966T).

A novel Gram-stain-negative, aerobic, rod-shaped strain designated PG04T was isolated from the rhizosphere of watermelon plants cultivated in Beijing, China. A polyphasic taxonomic study was performed on the new isolate. On the basis of 16S rRNA gene sequence similarity studies, isolate PG04T belonged clearly to the genus Hansschlegelia and was most closely related to Hansschlegelia zhihuaiae (97.3 % similarity to the type strain). The predominant respiratory quinone was ubiquinone 10 (Q-10) and the polar lipid profile was composed of the major lipids diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. The major fatty acids were C18 : 1ω7c (41.3 %), C19 : 0 cyclo ω8c (30.6 %) and C16 : 0 (19.1 %). The G+C content of the DNA was about 64.4 mol%. DNA–DNA hybridization experiments showed 34.4 % relatedness between strain PG04T and H. zhihuaiae DSM 18984T. The results of physiological and biochemical tests and differences in fatty acid profiles allowed clear phenotypic differentiation of strain PG04T from the most closely related species in the genus, H. zhihuaiae . Strain PG04T therefore represents a novel species within the genus Hansschlegelia , for which the name Hansschlegelia beijingensis sp. nov. is proposed, with the type strain PG04T ( = DSM 25481T = ACCC 05759T).
