Abstract

A Gram-stain-negative, aerobic, non-flagellated, coccoid, ovoid or rod-shaped bacterial strain, TSTF-M16, was isolated from a tidal flat on the Yellow Sea, Republic of Korea. The neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain TSTF-M16 fell within a clade comprising the type strains of species. Strain TSTF-M16 exhibited 16S rRNA gene sequence similarities of 98.5 and 98.1 % to the type strains of and , respectively, and 96.2–97.8 % to the type strains of the other species. The average nucleotide identity and digital DNA–DNA hybridization values between the genomic sequences of strain TSTF-M16 and the type strains of 16 species were 70.6–74.2 and 17.9–19.0 %, respectively. The DNA G+C content of strain TSTF-M16 from genomic sequence data was 59.26 mol%. Strain TSTF-M16 contained Q-10 as the predominant ubiquinone and C 7 as the major fatty acid. The major polar lipids of strain TSTF-M16 were phosphatidylcholine, phosphatidylglycerol, one unidentified aminolipid and one unidentified lipid. Distinguished phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain TSTF-M16 is separated from recognized species. On the basis of the data presented here, strain TSTF-M16 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is TSTF-M16 (=KACC 21645=NBRC 114501).
