Deinococcus radiodurans (DR) exhibits strong resistance to ionizing radiation. In this study, by constructing a radiation-resistant genetically engineered strain overexpressing the Cs gene, the tolerance of the bacterium to aluminum ions was enhanced, thereby achieving the goal of microbial sustainable remediation of uranium-contaminated environments. Methods: 1. Extraction of the recombinant plasmid pRADK-Cs, transformation into DR, and verification. 2. Investigation of factors such as time and initial uranium concentration on the efficiency of uranium accumulation by the recombinant strain, ...
