Abstract

A Gram-staining-negative, rod-shaped and non-spore-forming bacterium, designated strain 333-1-0411, was isolated from a soil sample collected from Namucuo, Tibet Autonomous Region, China and characterized in a taxonomic study using a polyphasic approach. The major fatty acid components of strain 333-1-0411 were summed feature 3 (Cω7 and/or Cω6) and C; its major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. Q-8 was the dominant ubiquinone, and the G+C content of the genomic DNA was 66.7 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 333-1-0411 fell within the evolutionary radiation encompassed by the genus . The 16S rRNA gene sequence similarities between strain 333-1-0411 and recognized species of the genus ranged from 95.4 % to 97.2 %, and the most closely related strains were Y9 (97.2 %) and 45 (97.0 %). However, the DNA–DNA relatedness values between strain 333-1-0411 and Y9 and 45 were 20.2 % and 27.2 %, respectively. Based on the phenotypic, chemotaxonomic and phylogenetic properties, strain 333-1-0411 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 333-1-0411 ( = CGMCC 1.11014 = DSM 25159).
