Abstract

A Gram-negative, non-motile, non-spore-forming, slightly halophilic bacterial strain, DSW-5, was isolated from seawater off Dokdo, Korea, and subjected to a polyphasic taxonomic study. It grew optimally at 25–28 °C and in the presence of 2 % (w/v) NaCl. Strain DSW-5 contained MK-6 as the predominant menaquinone and iso-C, iso-C and iso-C 3-OH as the major fatty acids. The major polar lipids detected were phosphatidylethanolamine, three unidentified phospholipids and an amino-group-containing lipid. The DNA G+C content was 30.0 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DSW-5 was most closely related to the genus . Similarity values between the 16S rRNA gene sequences of strain DSW-5 and the type strains of recognized species were in the range 96.2–96.8 %. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain DSW-5 (=KCTC 12392=DSM 17204) was classified in the genus as the type strain of a novel species, for which the name sp. nov. is proposed.
