A Gram-positive, short-rod shaped and non-motile bacterium Deinococcus actinosclerus BM2(T), resistant to gamma and UV radiation, was isolated from a soil sample collected in South Korea. Strain BM2(T) showed high resistance to gamma radiation with D10 value of 9 kGy. The complete genome of D. actinosclerus BM2(T) consists of a single chromosome (3,264,334bp). The genome features showed the presence of intracellular proteases that help to eliminate radiation-induced ROS during recovery from ionizing radiation damage.
从韩国采集的土壤样本中分离出了一株革兰氏阳性、短杆状且无运动性的耐辐射异常球菌（Deinococcus actinosclerus）BM2(T)，它对γ射线和紫外线具有抗性。菌株BM2(T)对γ射线表现出高抗性，其D10值为9千戈瑞。耐辐射异常球菌BM2(T)的完整基因组由一条染色体（3,264,334碱基对）组成。基因组特征显示存在细胞内蛋白酶，这些蛋白酶有助于在从电离辐射损伤中恢复的过程中清除辐射诱导的活性氧。
