A novel aerobic, psychrotolerant, yellow-to-orange bacterium (strain 0423) was isolated from the China No. 1 glacier. Strain 0423 displayed phenotypic and chemotaxonomic features of the genus , containing anteiso-C and iso-C as the major fatty acids. The temperature range for growth was 4–28 °C, with optimum growth at 20–21 °C. The genomic DNA G+C content was 49 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain 0423 was related to members of the genus , sharing the highest sequence similarities with the type strains of , , and . On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness data, a novel species, sp. nov., is proposed. The type strain is 0423 (=CGMCC 1.6846 =JCM 15088).
