Abstract

A Gram-stain-negative, strictly aerobic, cream-coloured, motile, chemoheterotrophic, rod-shaped bacterium, designated strain KMU-32, was isolated from seawater at Najeong Beach in Korea. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the family of the class and that it showed highest sequence similarity (98.2 %) to CC-AMHB-3. The DNA–DNA relatedness value between strain KMU-32 and CC-AMHB-3was 48.5 ± 4 %. The DNA G+C content of strain KMU-32 was determined to be 63.7 mol%. Ubiquinone 10 (Q-10) was the sole respiratory quinone. The predominant cellular fatty acid was C 7. Strain KMU-32 had diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified aminolipid and an unidentified lipid as polar lipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, strain KMU-32 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KMU-32 (= KCTC 42981 = NBRC 111834).
