Pseudochrobactrum glaciei sp. nov., isolated from sea ice collected from Peter the Great Bay of the Sea of Japan

An aerobic, Gram-negative, non-pigmented, non-motile bacterium, KMM 3858^T, 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 recA gene sequences placed strain KMM 3858^T within the genus Pseudochrobactrum. The major chemotaxonomic characteristics were found to be the presence of phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unknown aminolipid and phosphatidylcholine, major fatty acids C_{18 : 1}ω7c and C_{19 : 0} cyclo, and ubiquinone Q-10, confirming the affiliation of strain KMM 3858^T to the genus Pseudochrobactrum. On the basis of the phylogenetic analysis and the physiological and biochemical characterization, strain KMM 3858^T should be classified as representing a novel species of the genus Pseudochrobactrum, for which the name Pseudochrobactrum glaciei sp. nov. is proposed. The type strain is strain Pi26^T (=KMM 3858^T=NRIC 0733^T=JCM 15115^T).
