Abstract

A Gram-negative, non-flagellated, non-spore-forming and rod-shaped bacterial strain, SW-152, was isolated from sea water of the Yellow Sea in Korea, and subjected to a polyphasic taxonomic study. Strain SW-152 grew optimally at 30 °C and in the presence of 2–3 % (w/v) NaCl. It contained MK-7 as the predominant menaquinone and iso-C and iso-C as the major fatty acids. Polar lipids detected in strain SW-152 were phosphatidylethanolamine, diphosphatidylglycerol and unidentified lipids. The DNA G+C content was 40·3 mol%. Phylogenetic trees based on 16S rRNA gene sequences exhibited that strain SW-152 forms a distinct evolutionary lineage within the (CFB) group. Strain SW-152 exhibited low 16S rRNA similarity levels of less than 89·4 % to members belonging to the CFB group. Phenotypic properties of strain SW-152 differentiate it from phylogenetically related taxa. On the basis of phenotypic and phylogenetic data, strain SW-152 (=KCTC 12312=JCM 12600) was classified in a novel genus and species, gen. nov., sp. nov.
