Deinococcus malanensis sp nov., isolated from radiation-polluted soil

A Gram-staining positive, non-spore forming, short rod-shaped and coccus-shaped, non-motile, pink-colored, gamma- and UV-resistant strain, designated T93(T) 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 T93(T) shared the highest 16 S rRNA gene sequence similarity with Deinococcus deserti VCD115(T) (97.54%). The genomic DNA G+C content of the isolate T93(T) was 61.7 mol%. The predominant menaquinone was MK-8, while the major cellular fatty acids were iso-C-16:0, C-15:1 omega 6c, C-16:0, C-17:1 omega 8c and Summed Feature 3 (comprising C-16:1 omega 7c and/or C-16:1 omega 6c). The major polar lipid profiles consisted of diphosphatidylglycerol and phosphatidylinositol mannoside. Based on the phenotypic and genotypic data, strain T93(T) 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 T93(T) (= KCTC 33563(T) = JCM 30331(T)).
