Abstract

A Gram-stain-negative, non-flagellated, motile (by gliding), yellow-pigmented, rod-shaped bacterial strain, designated L-4, was isolated from seawater of Baekdo harbour in the East Sea, Korea. Strain L-4 grew optimally at 37 °C, at pH 6.5–7.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain L-4 clustered with CAM030, a member of the family . Strain L-4 exhibited 16S rRNA gene sequence similarity values of 97.2 % to . CAM030 and less than 95.8 % to other members of the family . Strain L-4 and . CIP 108537 contained MK-6 as the predominant menaquinone. The fatty acid and polar lipid profiles of strain L-4 were similar to those of . CIP 108537. The DNA G+C content of strain L-4 was 35 mol% and DNA–DNA relatedness between strain L-4 and . CIP 108537 was 7 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, enable strain L-4 to be distinguished from . . On the basis of these data, strain L-4 is considered to represent a novel species of the genus for which the name sp. nov. is proposed; the type strain is L-4 (=KCTC 22661 =CCUG 58074). An emended description of the genus is also provided.
