An aerobic, Gram-negative, non-pigmented, non-motile bacterium, KMM 3858, was isolated from a sea-ice sample collected from Peter the Great Bay of the Sea of Japan, Russia, and subjected to a phenotypic and phylogenetic study. Comparative analyses based on the 16S rRNA and gene sequences placed strain KMM 3858 within the genus . The major chemotaxonomic characteristics were found to be the presence of phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unknown aminolipid and phosphatidylcholine, major fatty acids C 7 and C cyclo, and ubiquinone Q-10, confirming the affiliation of strain KMM 3858 to the genus . On the basis of the phylogenetic analysis and the physiological and biochemical characterization, strain KMM 3858 should be classified as representing a novel species of the genus , for which the name sp. nov. is proposed. The type strain is strain Pi26 (=KMM 3858=NRIC 0733=JCM 15115).
