Abstract A Gram-staining positive, non-spore forming, short rod-shaped and coccus-shaped, non-motile, pink-colored, gamma- and UV-resistant strain, designated T93T was isolated from soil of Malan area in Xinjiang Uyghur Autonomous Region, Northwest China. The taxonomic position of the new isolate was determined using a polyphasic approach. Strain T93T shared the highest 16 S rRNA gene sequence similarity with Deinococcus deserti VCD115T (97.54%). The genomic DNA G+C content of the isolate T 93T was 61.7 mol%. The predominant menaquinone was MK-8, while the major cellular fatty acids were iso-C16:0, C15:1 ω6c, C16:0, C17:1 ω8c and Summed Feature 3 (comprising C 16:1 ω7c and/or C16:1 ω6c). The major polar lipid profiles consisted of diphosphatidylglycerol and phosphatidylinositol mannoside. Based on the phenotypic

and genotypic data, strain T93T is considered to represent a novel species of the genus Deinococcus, for which the name Deinococcus malanensis sp. nov. is proposed. The type strain is T 93T (= KCTC 3 3563T = JCM 30331T). Keywords Deinococcus malanensis sp. nov. · Malan area · Polyphasic taxonomy
Introduction The genus Deinococcus was proposed by Brooks and Murray (1981) for a group of bacteria which are resistant to UV light, gamma radiation and desiccation (Mattimore and Battista 1996; de Groot et al. 2005; Callegan et al. 2008; Peng et al. 2009). Members of this genus are non-spore forming and non-motile, and exhibit a remarkable capacity to resist lethal doses of ionizing radiation (Moseley 1983; Smith et al. 1992; Minton 1994). Colonies of this genus are usually bright red, orange, or light pink in color (Callegan et al. 2008; Peng et al. 2009). At the time of writing this manuscript, the genus contains 58 validly described species
