Abstract

A bacterial strain, UDC377, was isolated from seawater samples collected at Seo-do on the coast of Dokdo island in the East Sea, and was subjected to taxonomic study using a polyphasic approach. Strain UDC377 was pale-yellow, Gram-staining-negative, non-motile, rod-shaped and aerobic. The strain grew optimally at 25–28 °C, in the presence of 2 % (w/v) NaCl and at pH 7.0–7.5. Strain UDC377 produced carotenoid pigments; however, it did not produce flexirubin-type pigments. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain UDC377 clustered with members of the genus and appeared most closely related to KYW566 (96.0 % 16S rRNA gene sequence similarity) followed by MA-My1 (95.0 %), CL-TF09 (94.9 %), S7-2 (94.1 %) and IMCC1507 (94.0 %). The DNA G+C content of strain UDC377 was 30.8 mol%. Strain UDC377 contained MK-6 as the predominant menaquinone, iso-C 3-OH, iso-C and iso-C 3-OH as the major fatty acids, and phosphatidylethanolamine, two unknown aminolipids and six unknown lipids as the major polar lipids. Based on phenotypic properties and phylogenetic data presented, strain UDC377 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is UDC377 ( = DSM 24956 = KCTC 23668).
