Description of sp. nov., isolated from seawater of the East Sea in Korea, transfer of Labrenz 2000 to the genus as comb. nov. and emended description of the genus Free

Abstract

A Gram-negative, non-motile and rod-, oval- or coccoid-shaped bacterial strain, DSW-25, which is phylogenetically closely related to the genera and , was isolated from seawater of the East Sea, Korea, and subjected to a polyphasic taxonomic study. Strain DSW-25 grew optimally at pH 7.0–8.0 and at 25 °C. It contained Q-10 as the predominant ubiquinone and C 7 as the major fatty acid. Major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The DNA G+C content was 56.9 mol%. Strain DSW-25 exhibited 16S rRNA gene sequence similarity values of 98.4 % to the type strain of and of 96.6–97.6 % to species. There were no distinct phenotypic, particularly chemotaxonomic, properties to differentiate and strain DSW-25 from the genus . DNA–DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain DSW-25 differs from recognized species and . On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strain DSW-25 was classified in the genus as a member of a novel species, for which the name sp. nov. is proposed. The type strain is strain DSW-25 (=KCTC 12864 =JCM 14565). It is also proposed that be transferred to the genus as comb. nov.
