Abstract

A moderately halophilic Gram-negative bacterium, strain DS2, was isolated from seawater from the East Sea in Korea. Strain DS2 grew at salinities of 0–14 % (w/v) NaCl and at temperatures in the range 10–38 °C. The cells were non-motile short rods (1.0–1.4 μm in width and 1.6–2.6 μm in length) and the major fatty acids were C 7 and 11-methyl C 7. The genomic DNA G+C content was 72.0 mol% and the predominant lipoquinone was Q-10. The major cellular phospholipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS2 formed a distinct phyletic line from the genus within the . The levels of 16S rRNA gene sequence similarity with respect to the type strains of related genera were below 94 %. On the basis of physiological and phylogenetic properties, strain DS2 represents a novel genus and species of the , for which the name gen. nov., sp. nov. is proposed. The type strain is DS2 (=KCTC 12586=DSM 17890).
