Description of sp. nov. and proposal of the genera , , and as synonyms of .

Two Gram-stain-negative, aerobic, ovoid to short rod-shaped bacterial strains, designated as WL0062 and WL0115, were isolated from coastal zone of the Yellow Sea, Jiangsu Province, PR China, respectively. Strain WL0062 grew optimally at 28 °C, pH 7.0-8.0 and with 1.0-3.0% (w/v) NaCl. Strain WL0115 grew optimally at 28 °C, pH 6.0-7.0 and with 1.0-3.0% (w/v) NaCl. In the bac120 tree, strains WL0062 and WL0115 clustered together with B57. The respiratory quinone of both strains was ubiquinone-10. The major polar lipids of both strains were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, glycolipid, phosphatidylmonomethylethanolamine, and one unidentified polar lipid. The major fatty acids of strain WL0062 were summed features 8 (C 6 and/or C 7). The major fatty acids of strain WL0115 were summed features 8 (C 6 and/or C 7), C, iso-C 5 and C 6/9/12/15 (arachidonic acid). The G+C content of genomic DNA of strains WL0062 and WL0115 was 64.0 mol% in both of them. Combined with the analysis of average nucleotide identity, average amino acid identity, and digital DNA-DNA hybridization, strain WL0062 represents a novel species of the genus , for which the name sp. nov is proposed. The type strain is WL0062 (=MCCC 1K06014=JCM 34676=GDMCC 1.2427). Strain WL0115 (=MCCC 1K07531=JCM 35568=GDMCC 1.3088) should belong to the same species as B57. In addition, on the basis of phylogenomic relationship and phenotypical characteristics, the genera , , and are proposed as synonyms of .
