| Abstract |
A novel psychrotolerant, Gram-negative, aerobic bacterium, designated strain 537T, was isolated from sea-ice samples from the Arctic. Strain 537T was able to grow at 4-26 degrees C, with optimum growth occurring at 20-21 degrees C. Strain 537T had Q-8 as the major respiratory quinone and contained iso-C15:0 2-OH and/or C16:1 omega7c (22.95 %), C15:1 (17.64 %) and C17:1 omega8c (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).
