A novel psychrotolerant, Gram-negative, motile bacterium, designated strain 328, was isolated from sea-ice samples collected off the Canadian Basin of the Arctic Ocean (7 ° 23′ 14″ N 14 ° 06′ 55″ W). Strain 328 was able to grow at 0–37 °C, with optimum growth at 25–27 °C. It possessed phosphatidylethanolamine and phosphatidylglycerol as major phospholipids and C 3-OH (31.78 %), C 7 (27.50 %) and iso-C 2-OH and/or C 7 (19.22 %) as predominant cellular fatty acids. The DNA G+C content of strain 328 was 45.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 328 was a member of the genus (92.7–96.0 % 16S rRNA gene sequence similarity). On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain 328 was considered to represent a novel species of the genus . The name sp. nov. is proposed, with strain 328 (=CGMCC 1.6498=JCM 14976) as the type strain.
