A yellow-pigmented, moderately thermotolerant bacterial strain, designated S3-3, was isolated from desert sand in Xinjiang province, China, and subjected to a polyphasic taxonomic characterization. This isolate was Gram-negative, aerobic and motile. Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain S3-3 is phylogenetically affiliated to the genus . Strain S3-3 exhibited levels of 16S rRNA gene sequence similarity of less than 96.3 % to the type strains of all species, making it clear that strain S3-3 represents a species that is separate from previously recognized species. Its major fatty acids were summed feature 8 (C 6 and/or C 7), summed feature 3 (C 7 and/or iso-C 2-OH) and C cyclo 8. The major isoprenoid quinone was Q-9. The DNA G+C content was 60.9 mol%. On the basis of phylogenetic, phenotypic and chemotaxonomic analysis, strain S3-3 should be classified within a novel species of the genus , for which the name sp. nov. is proposed. The type strain is S3-3 (=CCTCC AB 207151 =NRRL B-51270).
