A Gram-staining-negative, non-motile, non-pigmented and rod-shaped bacterial strain, designated IMCC12053(T), was isolated from coastal surface seawater of the Yellow Sea, Korea. Optimal growth of strain IMCC12053(T) was observed at 30 degrees C, pH 7.0 and in the presence of 2% (w/v) NaCl. 16S rRNA gene sequence comparisons showed that strain IMCC12053(T) was most closely related to Celeribacter baekdonensis L-6(T) (97.5% similarity) and Celeribacter neptunius H 14(T) (96.0%). Strain IMCC12053(T) formed a robust phylogenetic clade with members of the genus Celeribacter. The DNA DNA relatedness value between IMCC12053(T) and C. baekdonensis was far lower than 70% (35.7-42.5%), which indicated that strain IMCC12053T is a novel genomic species of the genus Celeribacter. The major respiratory isoprenoid quinone was ubiquinone-10 (Q-10) and major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and aminolipids. The DNA G+C content was 61.0 mol%. On the basis of genotypic and phenotypic data collected in this study, it is proposed that strain IMCC12053(T) represents a novel species of the genus Celeribacter, for which the name Celeribacter marinus sp. nov. is proposed. The type strain is IMCC12053(T) (=KACC 17482(T)=NBRC 109702(T)).
