A Gram-staining-negative, aerobic, light brown pigment bacterium, designated strain CE80 was isolated from marine sponge in Jeju Island, Republic of Korea. Strain CE80 grew optimally at 25°C, in the range of pH 5.0-11.0 (optimum 7.0-8.0), and with 1.0-5.0% NaCl (optimum 1-3% (w/v)). Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain CE80 belonged to the genus and was closely related to YC6927 (98.3%), DFL-11 (96.6%), IAM 12614 (96.6%) mano18 (96.5%) and CECT 5094 (96.2%). The major fatty acids of strain CE80 were C ω7c, and summed feature. The polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamin, one unidentified aminolipid, one phospholipid and four unidentified lipids. The DNA G+C content of strain CE80 was 55.9 mol%. The major respiratory quinone was Q-10. DNA-DNA relatedness between strain CE80 and YC6927 was 56.1±2.8%. On the basis of physiological and biochemical characterization and phylogenetic and chemotaxonomic analysis, strain CE80 represents a novel species of the , for which the name sp. nov., is proposed. The type strain is CE80 (=KCTC 42849 =JCM 31309).
