A Gram-stain-negative, non-motile, ovoid- to rod-shaped bacterium, designated HDW-9T, belonging to the class Alphaproteobacteria, was isolated from seawater of the Yellow Sea, Korea. Strain HDW-9T grew optimally at pH 7.0-8.0, at 30 °C and with 2-3% (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain HDW-9T clustered with Roseovarius crassostreae CV919-312T, with which it exhibited 95.5% 16S rRNA gene sequence similarity. Strain HDW-9T exhibited 92.5-94.7% 16S rRNA gene sequence similarity with the other type strains of species of the genus Roseovarius. Strain HDW-9T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The DNA G+C content was 58.3 mol%. Differential phenotypic properties distinguished strain HDW-9T from the other members of the genus Roseovarius. Strain HDW-9T is considered to represent a novel species of the genus Roseovarius, for which the name Roseovarius marinus sp. nov. is proposed. The type strain is HDW-9T (=KCTC 22805T =CCUG 58403T).
