Salinibacterium xinjiangense sp nov., a psychrophilic bacterium isolated from the China No. 1 glacier

A novel psychrophilic, Gram-positive, yellow-pigmented and aerobic bacterium, strain 0543(T), was isolated from the China No. 1 glacier. Strain 0543(T) was able to grow at 4-23 degrees C, with optimum growth at 18-19 degrees C. The major fatty acids were anteiso-C-15: 0 (58.36%), iso-C-16: 0 (21.13 %), iso-C-14: 0 (10.25%) and anteiso-C-17: 0 (7.16%). The genomic DNA G+C content was 63.5 mol% and the major menaquinone was MK-10. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 0543(T) represented a lineage within the family Microbacteriaceae, with the highest similarity of 97.4 % with Salinibacterium amurskyense KMM 3673(T). On the basis of polyphasic, chernotaxonomic, physiological and biochemical evidence from this study, the novel species Salinibacterium xinjiangense so. nov. is proposed-, the type strain is 0543(T)(=CGMCC 1.5381(T) =JCM 13926(T)).
