| Abstract |
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)omega7c 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)).
