Abstract

An aerobic, Gram-stain-negative, rod-shaped bacterium, designated strain HMF2268, was isolated from a lagoon in the Republic of Korea. Comparative 16S rRNA gene sequence analysis showed that strain HMF2268 belonged to the genus Polaribacter and was most closely related to Polaribacter huanghezhanensis SM1202 (96.8 % similarity). Cellular fatty acids were dominated by iso-C15 : 0, iso-C15 : 0 3-OH, anteiso-C15 : 0 and iso-C15 : 1 G. The predominant respiratory quinone was menaquinone-6 (MK-6). The major polar lipids were phosphatidylethanolamine, three unidentified aminolipids and two unidentified polar lipids. The DNA G+C content was 34.3 mol%. Based on the polyphasic taxonomic analyses, it is concluded that strain HMF2268 represents a novel species of the genus Polaribacter , for which the name Polaribacter lacunae sp. nov. is proposed. The type strain is HMF2268 (=KCTC 42191=CECT 8862).
