sp. nov., isolated from a tidal flat Free

Abstract

A Gram-stain-negative, non-motile, aerobic and rod-shaped bacterium, designated OITF-20, was isolated from the tidal flat in Oido, an island of South Korea. The novel strain grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain OITF-20 fell within the clade comprising the type strains of species of the genus . Strain OITF-20 exhibited 16S rRNA gene sequence similarity values of 97.8, 97.6 and 97.6 % to the type strains of , and , respectively, of 94.9–96.8 % to the type strains of the other species of the genus and of less than 93.4 % to the type strains of the other recognized species. Strain OITF-20 contained MK-6 as the predominant menaquinone and iso-C 3-OH, Cω6 and iso-C as the major fatty acids. The major polar lipids of strain OITF-20 were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain OITF-20 was 31.1 mol% and its mean DNA–DNA relatedness values with the type strains of , and were 17–27 %. The differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain OITF-20 is separated from other recognized species of the genus . On the basis of the data presented, strain OITF-20 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is OITF-20 (=KCTC 52501=NBRC 112458).
