Abstract

A Gram-negative, motile, yellow-pigmented, slightly halophilic bacterial strain, SW-151, was isolated from sea water of the Yellow Sea in Korea, and subjected to a polyphasic taxonomic study. The isolate grew optimally at 30 °C and in the presence of 2–3 % NaCl. Strain SW-151 was characterized chemotaxonomically as having Q-10 as the predominant respiratory lipoquinone and C 7, C 7 and/or iso-C 2-OH and C 6 as the major fatty acids. Sphingoglycolipid, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine were the major polar lipids. The DNA G+C content was 58 mol%. 16S rRNA gene sequence analysis showed that strain SW-151 joins the evolutionary radiation enclosed by the genus . Similarities between the 16S rRNA gene sequences of strain SW-151 and the type strains of species ranged from 92·3 to 94·3 %, which is low enough to categorize strain SW-151 as a species distinct from previously described species. On the basis of phenotypic properties and phylogenetic distinctiveness, strain SW-151 (=KCTC 12232=DSM 16223) should be classified as a novel species, for which the name sp. nov. is proposed.
