Abstract

A Gram-stain-negative, aerobic, non-motile and ovoid- or rod-shaped bacterial strain, designated HSMS-39, was isolated from marine sand sampled at Hongsung, Republic of Korea. Strain HSMS-39 grew optimally at 30 °C and in the presence of 1.0–2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain HSMS-39 fell within the clade comprising the type strains of species, clustering with the type strain of showing 16S rRNA gene sequence similarity of 99.1 %. It exhibited 16S rRNA gene sequence similarities of less than 95.5 % to the type strains of the other species. Strain HSMS-39 contained MK-7 as the predominant menaquinone and iso-Cω9, iso-C and summed feature 3 (Cω7 and/or Cω6) as the major fatty acids. The major polar lipids of strain HSMS-39 were phosphatidylethanolamine and one unidentified phospholipid. The DNA G+C content of strain HSMS-39 was 60.0 mol%. The mean DNA–DNA relatedness value between strain HSMS-39 and the type strain of was 15 %. The average nucleotide identity value between strain HSMS-39and the type strain of was 81.87 %. The phylogenetic and genetic data and differential phenotypic properties indicated that strain HSMS-39 is separated from other recognized species of the genus . On the basis of the polyphasic data, strain HSMS-39 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HSMS-39 (=KACC 19866=NBRC 113585).
