gen. nov., sp. nov., isolated from a tidal flat Free

Abstract

A Gram-stain-negative, non-motile, aerobic and coccoid, ovoid or rod-shaped bacterial strain, designated BS-W9, was isolated from a tidal flat of the South Sea, South Korea. Strain BS-W9 grew optimally at 25–30 °C, at pH 7.0–8.0 and in the presence of approximately 2.0 % (w/v) NaCl. Phylogenetic trees, based on 16S rRNA gene sequences, revealed that strain BS-W9 clustered with the type strain of , showing a highest sequence similarity of 97.3 %. It exhibited sequence similarity values of less than 95.6 % to the type strains of other species with validly published names. Strain BS-W9 contained Q-10 as the predominant ubiquinone and Cω7 as the predominant fatty acid. The major polar lipids of strain BS-W9 were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, one unidentified lipid and one unidentified aminolipid. The fatty acid and polar lipid profiles of strain BS-W9 were distinguished from those of the type strains of and other phylogenetically related genera. The DNA G+C content of strain BS-W9 was 53.2 mol% and its mean DNA–DNA relatedness value with RA2-3 was 14 %. On the basis of the phylogenetic, chemotaxonomic and other phenotypic properties, strain BS-W9 is considered to represent a novel genus and species within the family , for which the name gen. nov., sp. nov. is proposed. The type strain of is BS-W9 ( = KCTC 42348 = CECT 8726).
