Abstract

A Gram-negative, rod-shaped, non-spore-forming, slightly halophilic bacterium (strain TF-17) was isolated from an intertidal sediment from the Yellow Sea, Korea. Pigment of strain TF-17 was similar to that of , but different from those of and . Strain TF-17 was distinguishable from by some phenotypic properties, including motility, optimal growth temperature and others. Phylogenetic analysis based on 16S rDNA sequences showed that strain TF-17 clustered with the type strains of the three species with validly published names. Strain TF-17 exhibited 16S rDNA sequence similarity levels of 95·1–95·7 % to the type strains of the three species. The predominant respiratory lipoquinone found in strain TF-17 was ubiquinone-8. The major fatty acid was iso-C and significant amounts of iso-C 3-OH and iso-C 9 were also present. The DNA G+C content of strain TF-17 was 59·9 mol%. Levels of DNA–DNA relatedness between strain TF-17 and the type strains of the three species were in the range 10·0–13·0 %. On the basis of phenotypic and phylogenetic data and genotypic distinctiveness, strain TF-17 (=KCCM 41774=JCM 12187) is proposed as the type strain of a novel species of the genus , sp. nov.
