Abstract

A Gram-stain-negative, rod-shaped and facultative anaerobic strain named YE-B6 was isolated from the intestine of abalone, . The reactions of oxidase and catalase were both positive. Strain YE-B6 could grow at 10–37 °C (optimum, 28–33 °C), at pH 7–9 (optimum, pH 7) and in salinity of 0–8 % NaCl (w/v; optimum, 2 %). The 16S rRNA gene sequence of strain YE-B6 had maximum sequence similarities to H1304 (98.0 %), DQHS21 (97.4 %), JC131 (97.4 %) and CL-GR15 (97.3 %). Results of phylogenetic analysis showed that it was affiliated to the genus within the order in the . The respiratory quinone of strain YE-B6 was Q-10. The cellular fatty acids mainly comprised C 7 and summed feature 3 (Cω6 and/or Cω7). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, two unidentified aminolipids, two unidentified polar lipids and one unidentified phospholipid. The G+C content of strain YE-B6 was 55.6 mol%. Based on its genotypic, physiological and biochemical characteristics, strain YE-B6 represented a novel species within the genus , for which the name sp. nov. is proposed. The type strain of the new species is YE-B6 (=MCCC 1A13131=KCTC 62716).
