Abstract

A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterial strain, designated W-WS13, was isolated from wood falls collected around Wando, an island in the South Sea of South Korea, and subjected to a polyphasic taxonomic study. Strain W-WS13 grew optimally at 30 °C, at pH 7.5 and in the presence of 0.5 % NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain W-WS13 belonged to the genus , clustering robustly with the type strain of , sharing 95.9 % sequence similarity. Strain W-WS13 exhibited 16S rRNA gene sequence similarity of 90.1–95.6 % to the type strains of the other species of the genus . Strain W-WS13 contained MK-7 as the predominant menaquinone and iso-C, summed feature 3 (Cω7 and/or Cω6) and iso-C 3-OH as the major fatty acids. The major polar lipid detected in strain W-WS13 was phosphatidylethanolamine. The DNA G+C content of strain W-WS13 was 36.9 mol%. Phylogenetic distinctiveness and differential phenotypic properties of strain W-WS13 revealed that the novel strain is separated from recognized species of the genus . On the basis of the data presented, strain W-WS13 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is W-WS13 ( = KCTC 42500 = CECT 8725).
