Abstract

A Gram-stain-negative, aerobic, non-motile and coccoid, ovoid or rod-shaped bacterium, designated W-WS1, was isolated from wood falls collected around Wando, an island located in the South Sea, Republic of Korea. Strain W-WS1 grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 0–3.0 % (w/v) NaCl. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain W-WS1 belonged to the genus , clustering coherently with the type strains of , , , and , showing 94.3–96.3 % sequence similarity. Strain W-WS1 exhibited 16S rRNA gene sequence similarity values of 91.2–94.0 % to the type strains of other species of the genus . Strain W-WS1 contained MK-7 as the predominant menaquinone and iso-C, iso-C 3-OH and summed feature 3 (Cω7 and/or Cω6) as the major fatty acids. The major polar lipids detected in strain W-WS1 were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain W-WS1 was 37.7 mol%. The differential phenotypic properties, together with its phylogenetic distinctiveness, revealed that strain W-WS1 is separated from recognized species of the genus . On the basis of the data presented, strain W-WS1 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is W-WS1 ( = KCTC 42174 = CECT 8669).
