Strain 537T was able to grow at 4–26 °C, with optimum growth occurring at 20–21 °C. Strain 537T had Q-8 as the major respiratory quinone and contained iso-C15 : 0 2-OH and/or C16 : 1 ω7c (22.95 %), C15 : 1 (17.64 %) and C17 : 1 ω8c (13.74 %) as the predominant cellular fatty acids. The genomic DNA G+C content was 38.9 mol%. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 537T formed a coherent cluster within the genus Colwellia. The highest level of 16S rRNA gene sequence similarity (97.5 %) exhibited by strain 537T was obtained with respect to the type strain of Colwellia aestuarii. On the basis of phenotypic, chemotaxonomic and phylogenetic properties and DNA–DNA relatedness data, strain 537T represents a novel species of the genus Colwellia, for which the name Colwellia polaris sp. nov. is proposed. The type strain is 537T (=CGMCC 1.6132T =JCM 13952T).", }
