<i>Cryobacterium Inferilacus</i> sp. nov., a Pshychrophilic Ureolitic Bacterium From Lake Untersee in Antarctica.

ABSTRACT: The psychrophilic aerobic heterotrophic bacterium, strain 1639^T, was isolated from the low-temperature Lake Untersee in Antarctica. The bacterium was Gram-positive, non-motile, yellow-green-pigmented, non-spore-forming, and a pleomorphic rod. Growth was observed at temperatures of 0-25 °C with an optimum at 10 °C. The strain used urea as a nitrogen source. The major fatty acids were i-C_16:0 (49.69%), ai-C_15:0 (17.59%), and C_16:1 branched (12.03%). Identified polar lipids were phosphatidylglycerols and a glycolipid. The respiratory quinone was determined to be MK-10. The genomic DNA G+C content was 68.03 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 1639^T was a member of the genus Cryobacterium
