Abstract

A novel psychrotolerant, Gram-positive, yellow-pigmented, aerobic bacterium, strain 0549, was isolated from the China No. 1 glacier. The cells of the isolate were catalase-positive, motile, irregular rods. The diamino acid content of the cell-wall peptidoglycan was determined to be 2,4-diaminobutyric acid. Strain 0549 was able to grow at 4–27 °C, with optimum growth occurring at 20–22 °C. The major fatty acids were anteiso-C, anteiso-C, iso-C and anteiso-C. The genomic DNA G+C content was 67 mol%. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 0549 belonged to the genus and exhibited 96.5 % similarity to JCM 1463. On the basis of the phenotypic, chemotaxonomic and phylogenetic properties and the DNA–DNA relatedness data, strain 0549 represents a novel species of the genus , for which the name is proposed. The type strain is 0549 (=CGMCC 1.5382=JCM 13925).
