Abstract

A novel Gram-negative, aerobic, non-motile and rod-shaped bacterium, designated strain WM67, was isolated from the gut of an abalone () collected from the northern coast of Jeju Island in Korea. Phylogenetic analyses based on the 16S rRNA gene sequence indicated that strain WM67 clustered in the genus , and the highest sequence similarity was shared with (98.0 % similarity to the type strain). Optimal growth of the isolate occurred at 30 °C, pH 7–8 and with 1 % (w/v) NaCl. The major cellular fatty acids were summed feature 8 (Cω7 and/or Cω6) and C. Ubiquinone Q-10 was the major respiratory quinone. The polar lipids of strain WM67 comprised phosphatidylserine, phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, an unidentified glycolipid and three unidentified lipids. The genomic DNA G+C content was 66.5 mol%. DNA–DNA hybridization indicated <17 % genomic relatedness to other members of the genus . The physiological, biochemical, chemotaxonomic and genotypic analyses indicated that strain WM67 represents a novel species of , for which the name sp. nov. is proposed. The type strain is WM67 ( = KACC 17214 = JCM 18872).
