gen. nov., sp. nov., a gamma radiation-resistant bacterium in the family , isolated from desert sand Free

Abstract

A Gram-negative, rod-shaped, strictly aerobic bacterium, strain 2622, was isolated from gamma-irradiated soil sampled from the Taklimakan desert in Xinjiang, China. Phylogenetic analyses showed that strain 2622 formed a distinct lineage in the family and shared 91.7 and 90.1 % 16S rRNA gene sequence similarity with its closest relatives, the type strains of and , respectively. The DNA G+C content of strain 2622 was 71.4 mol% and the isoprenoid quinone was ubiquinone Q-10. Based on phenotypic and chemotaxonomic data and phylogenetic analysis, strain 2622 is considered to represent a novel species of a new genus in the family , for which the name gen. nov., sp. nov. is proposed. The type strain of is strain 2622 ( = CCTCC AB 208152  = KCTC 22436).
