摘　　要：奇球菌属(Deinococcus)是迄今为止发现的最具抗辐射能力的一类细菌,在环境治理上具有巨大的应用前景,其中的耐辐射奇球菌(Deinococcus radiodurans)还是研究DNA损伤修复和极端抗性应激机制的模式生物。本文介绍了奇球菌属最新的研究进展,对奇球菌属生理结构特点和抗性机制进行了讨论,并对其在生物技术上的应用前景进行了展望,以期为后续研究者们快速了解该属细菌及其在生产上的应用提供支撑。All known members of the genus Deinococcus have strong radioresistance and great application prospect in environmental managements. Deinococcus radiodurans is the typical species of this genus and its mechanism of DNA damage repair and extreme stress resistance was studied very well. This paper summarized recent progress in the study of Deinococcus including physiology and mechanisms of radioresistance among its members, and the prospect of the application of these members in biotechnology, which may help researchers studying this new genus and its applications in production in the future.
