摘要:
This study reveals the transformation of the Super Uranyl-binding Protein (SUP) gene with high uranium selectivity and binding affinity into Deinococcus Radiodurans, a genetically modified bacterium with high uranium adsorption capacity and resistance to radiation. The optimal adsorption conditions and mechanism of Deino-SUP for uranium under different environmental conditions were investigated. The results demonstrated the successful construction of Deino-SUP, a recombinant strain with excellent uranium adsorption capacity and radiation resistance. The adsorption of uranium by Deino-SUP is ma...
