Abstract

A Gram-staining-negative, oval- or rod-shaped, non-motile bacterial strain, designated HDW-36, was isolated from seawater off the Korean peninsula. Strain HDW-36 was found to grow optimally at pH 7.0–8.0, at 25 °C and in the presence of 2–3 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain HDW-36 falls within the clade comprising thespecies of the genus , clustering with the type strains of and , with which it exhibited 95.9 % and 95.2 % sequence similarity values, respectively. The 16S rRNA gene sequence similarity values between strain HDW-36 and type strains of other species of the genus were 88.4–92.8 %. Strain HDW-36 was found to contain MK-7 as the predominant menaquinone and summed feature 3 (C 6 and/or C 7), iso-C and C as the major fatty acids. The major polar lipids were identified as phosphatidylethanolamine and an unidentified lipid. The DNA G+C content of strain HDW-36 was determined to be 60.9 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrate that strain HDW-36 is distinguishable from other species of the genus . On the basis of the data presented, strain HDW-36 is considered to represent a novel species, for which the name sp. nov. is proposed. The type strain of is HDW-36 (=KCTC 42719=CECT 8901).
