abstract= A Gram-positive, non-motile, spherical, red-pigmented and facultatively anaerobic bacterium, designated strain I-0T, was isolated from a sand sample of the Gobi desert in Xinjiang Autonomous Region, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this isolate represents a novel member of the genus Deinococcus, with low sequence similarities (<94 %) to recognized Deinococcus species. The major cellular fatty acids were C16 : 1 ω7c and C16 : 0. Its polar lipid profile contained several unidentified glycolipids, phosphoglycolipids, phospholipids, pigments and an aminophospholipid. The peptidoglycan type was Orn–Gly2 (A3β) and the predominant respiratory quinone was MK-8. The DNA G+C content was 65.4 mol%. DNA–DNA relatedness between strain I-0T and Deinococcus radiodurans ACCC 10492T was 37 %. The strain was shown to be extremely resistant to gamma radiation (>15 kGy) and UV light (>600 J m−2). On the basis of the phylogenetic, chemotaxonomic and phenotypic data presented, strain I-0T represents a novel species of the genus Deinococcus, for which the name Deinococcus gobiensis sp. nov. is proposed. The type strain is I-0T (=DSM 21396T =CGMCC 1.7299T).,
