Roseivirga echinicomitans sp. nov., a novel marine bacterium isolated from the sea urchin Strongylocentrotus intermedius, and emended description of the genus Roseivirga
A novel strictly aerobic, heterotrophic, pink-pigmented, non-motile, Gram-negative, oxidase-, catalase-, β-galactosidase- and alkaline phosphatase-positive marine bacterium, designated strain KMM 6058T, was isolated from the sea urchin Strongylocentrotus intermedius and studied using a polyphasic taxonomic approach. The G+C content of the DNA of the isolate was 41·3 mol%. The predominant fatty acids were i15 : 1, i15 : 0, a15 : 0 and i17 : 0 3-OH. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain KMM 6058T formed a monophyletic clade with Roseivirga ehrenbergii, with 99 % similarity. On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacterium should be assigned to the genus Roseivirga as Roseivirga echinicomitans sp. nov. The type strain is KMM 6058T (=KCTC 12370T=LMG 22587T).
