A gram-negative, non-flagellated and ovoid- to rod-shaped bacterial strain, designated GSW-M15T, was isolated from seawater on the southern coast of South Korea. Strain GSW-M15T grew optimally at 30 °C, at pH 7.0–7.5 and in the presence of 2 % (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences revealed that strain GSW-M15T belonged to the genus Roseovarius. Strain GSW-M15T exhibited highest 16S rRNA gene sequence similarity values (98.3 and 97.5 %) to Roseovariushalotolerans HJ50T and Roseovariuspacificus 81-2T and 92.8-96.2 % sequence similarity values to the type strains of the other Roseovarius species. Strain GSW-M15T contained Q-10 as the predominant ubiquinone and C18:1ω7c and 11-methyl-C18:1ω7c as the major fatty acids. The major polar lipids detected in strain GSW-M15T were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and two unidentified lipids. The DNA G+C content of strain GSW-M15T was 62.9 mol% and its mean DNA–DNA relatedness values with R. halotolerans KCTC 22224T and R. pacificus LMG 24575T were 33 and 18 %, respectively. Differential phenotypic properties of strain GSW-M15T, together with the phylogenetic and genetic distinctiveness, demonstrated that this strain is distinguishable from other Roseovarius species. On the basis of the data presented here, strain GSW-M15T (=KCTC 23897T = CCUG 62218T) represents a novel species of the genus Roseovarius, for which the name Roseovarius litoreus sp. nov. is proposed.
