sp. nov., isolated from a tidal flat.

A Gram-staining-negative, aerobic, non-motile and coccoid, ovoid or rod-shaped bacterial strain, designated as JBTF-M21, was isolated from a tidal flat sediment on the Yellow Sea, Republic of Korea. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences indicated that JBTF-M21 fell within the clade comprising the type strains of species of the genus . JBTF-M21 exhibited 16S rRNA gene sequence similarities of 97.0-98.4 % to the type strains of , , , , , and and 93.7-96.6 % to the type strains of the other species of the genus . The ANI and dDDH values between JBTF-M21 and the type strains of , , and were 70.83-72.93 % and 18.0-18.8 %, respectively. Mean DNA-DNA relatedness values between JBTF-M21 and the type strains of , and were 12-24 %. The DNA G+C content of JBTF-M21 was 57.0 mol%. JBTF-M21 contained Q-10 as the predominant ubiquinone and Cω7 and Cω6 as the major fatty acids. The major polar lipids ofJBTF-M21 were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid. Distinguishing phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that JBTF-M21 is separated from species of the genus with validly published names. On the basis of the data presented, strain JBTF-M21 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is JBTF-M21 (=KACC 19864=NBRC 113584).
