An aerobic, Gram-stain-negative, rod-shaped bacterium, designated strain HMF2268T, was isolated from a lagoon in the Republic of Korea. Comparative 16S rRNA gene sequence analysis showed that strain HMF2268T belonged to the genus Polaribacter and was most closely related to Polaribacter huanghezhanensisSM1202T (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 HMF2268T represents a novel species of the genus Polaribacter, for which the name Polaribacter lacunae sp. nov. is proposed. The type strain is HMF2268T (=KCTC 42191T=CECT 8862T).
