title: Roseovarius aquimarinus sp. nov., a slightly halophilic bacterium isolated from seawater.
abstract: A Gram-stain-negative, non-spore-forming, rod-shaped, motile, facultatively anaerobic bacterium, designated CAU 1059T, was isolated from a seawater sample from Jeju Island, Republic of Korea. The bacterium grew optimally at 37 °C, at pH 7.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CAU 1059T belonged to the genus Roseovarius. It exhibited only 91.5-96.9 % sequence similarity to the type strains of recognized Roseovarius species. Similar to other species of the genus Roseovarius, strain CAU 1059T had ubiquinone-10 (Q-10) as the predominant ubiquinone and C16 : 0 and summed feature 8 (C18 : 1ω7c/ω6c) as the major fatty acids. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine; three unidentified phospholipids, two aminolipids, an aminophospholipid and nine other lipids were also found. The G+C content of the genomic DNA was 61.9 mol%. On the basis of the data provided, strain CAU 1059T should be classified as representing a novel species of the genus Roseovarius, for which the name Roseovarius aquimarinus sp. nov. is proposed. The type strain is CAU 1059T ( = KCTC 32014T = CCUG 64792T).
