Abstract

A Gram-stain-negative, non-flagellated, gliding, rod-shaped bacterial strain, designated WT-MY15, was isolated from wood falls in the South Sea in Korea and subjected to a polyphasic taxonomic study. Strain WT-MY15 grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain WT-MY15 clustered with the type strains of two species, exhibiting 16S rRNA gene sequence similarity values of 97.7–98.1 %. Strain WT-MY15 contained MK-6 as the predominant menaquinone. The fatty acid and polar lipid profiles of strain WT-MY15 were similar to those of L-4 and CIP 108537. The DNA G+C content of strain WT-MY15 was 42.8 mol% and its mean DNA–DNA relatedness values with L-4 and CIP 108537 were 8.3 and 5.6 %, respectively. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WT-MY15 is separate from the two recognized species of the genus . On the basis of the data presented, strain WT-MY15 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is WT-MY15 ( = KCTC 23673 = CCUG 61507). An emended description of the genus is also presented.
