Abstract

A Gram-negative, motile and egg-shaped bacterium, strain TF-218, was isolated from a tidal flat at Daepo Beach (Yellow Sea), Korea, and subjected to a polyphasic taxonomic analysis. Strain TF-218 grew optimally at pH 7.0–8.0 and 37 °C in the presence of 2 % (w/v) NaCl. It contained Q-10 as the predominant ubiquinone and C 7 and 11-methyl C 7 as the major fatty acids. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, two unidentified lipids and an aminolipid. The DNA G+C content was 64.9 mol%. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain TF-218 is phylogenetically closely related to the genera , and of the . The phylogenetic and chemotaxonomic similarities suggest that strain TF-218 represents a member of the genus . DNA–DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain TF-218 differs from the recognized species. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain TF-218 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is TF-218 (=KCTC 12794=JCM 13606).
