title: Celeribacter marinus sp. nov., isolated from coastal seawater.
abstract: 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 °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 IMCC12053(T) 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)).
