Abstract

A Gram-negative, rod-shaped, strictly aerobic micro-organism, designated strain CL-GR60, was isolated from coastal seawater from the East Sea, Korea. A 16S rRNA gene sequence analysis revealed a clear affiliation with the family . Phylogenetic analyses showed that strain CL-GR60 formed a robust cluster with the species of the genus at sequence similarity levels of 91.1–93.1 %; no other species in the family shared more than 90 % sequence similarity with strain CL-GR60. The strain grew optimally in the presence of 3–4 % sea salts at 30–35 °C and pH 7. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, two unidentified glycolipids, an unidentified phospholipid and an unidentified lipid. The strain contained C 7 (54.7 %), 11-methyl C 7 (19.3 %), C (14.4 %) as the predominant fatty acids. Ubiquinone-10 was the major quinone. The DNA G+C content was 62.9 mol%. On the basis of physiological data, fatty acid composition and results of phylogenetic analysis of the 16S rRNA gene sequence, strain CL-GR60 represents a novel genus and species within the family , for which the name gen. nov., sp. nov. is proposed. The type strain of is CL-GR60 (=KCCM 90027 =DSM 18995).
