摘要：
Deinococcus radiodurans (DR) is highly resistant to ionizing radiation. This study aims to convert dsrA gene into DR to construct radiation-resistant genetically engineered bacteria (Deino-dsrA) with high reducibility, so as to enhance the reducing and enrichment ability of DR. Methods: the recombinant vector pRADK-dsrA was extracted and transformed into DR. 1. Radiation resistant gene engineering bacteria containing dsrA gene were constructed successfully. 2. In the most favorable conditions,contributing to approximately 92.45% U (VI) was removed. 3. Autioxidant enzyme activities in Deino-dsr...
