A novel bacterial strain, designated 170, was collected from high latitude Arctic locations (77° 30′ N to approximately 81° 12′ N), including the Canadian Basin and Greenland Sea. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that strain 170 was related to members of the genus and had the highest 16S rRNA gene sequence similarity to . Cells were Gram-negative, psychrophilic, motile rods. The temperature range for growth was 4–15 °C, with optimum growth at 12 °C and at approximately pH 6.0–9.0. Strain 170 contained C 7, C, C 3-OH and C 7 as major fatty acids. The genomic DNA G+C content was 42.9 mol%. On the basis of phenotypic characterization, phylogenetic analysis and DNA–DNA relatedness data, strain 170 is considered to represent a novel species of the genus , for which the name is proposed. The type strain is 170 (=CGMCC 1.6130=JCM 13954).
