Abstract

A novel Gram-stain-negative bacterium, strain CY03, was isolated from sediment of the Yellow Sea, PR China. Cells of strain CY03 were rods, aerobic and non-flagellated. Growth occurred at 5–40 °C (optimum, 30 °C), pH 5.5–9.5 (pH 7.5) and with 0.5–9.0 % NaCl (1.5–2.0 %). The 16S rRNA gene sequence comparison showed affiliation to the family with (97.0 %) as the most closely related species, followed by members of the genus , (96.8 %) and (96.7 %). The major cellular fatty acids were cyclo-C 8, C, summed feature 8 (C 7 and/or C 6) and 11-methyl C 7. The polar lipids consisted of phosphatidylcholine, phosphatidylglycerol, one unidentified phospholipid, one unidentified aminolipid and five unidentified lipids. The predominant respiratory quinone was Q-10. The DNA G+C content of the type strain was 62.8 mol%. Based on the results of the polyphasic characterization for strain CY03, it represents a novel species of a novel genus of the family , for which the name gen. nov., sp. nov. is proposed. The type strain is CY03 (=CCTCC AB 2017195=KCTC 62198).
