Abstract 

A Gram-stain-negative, strictly aerobic, cream-coloured, motile, chemoheterotrophic, rod-shaped bacterium, designated strain KMU-32T, 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 Rhodobacteraceae of the class Alphaproteobacteria and that it showed highest sequence similarity (98.2 %) to Cribrihabitans neustonicus CC-AMHB-3T. The DNA-DNA relatedness value between strain KMU-32T and C. neustonicus CC-AMHB-3T was 48.5 ± 4 %. The DNA G+C content of strain KMU-32T was determined to be 63.7 mol%. Ubiquinone 10 (Q-10) was the sole respiratory quinone. The predominant cellular fatty acid was C18: 1ω7c. Strain KMU-32T 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-32T is considered to represent a novel species of the genus Cribrihabitans, for which the name Cribrihabitans pelagius sp. nov. is proposed. The type strain is KMU-32T (= KCTC 42981T = NBRC 111834T).
