Environmentally isolated bacteria have shown to be resistant to gamma ir- radiation up to a dose of 30,000 Gy. It has also been reported that the presence of ionizing radiation may induce ra- dio-resistance in bacteria. Recent demonstrations of the removal and immobilization of inorganic contaminants by microbial transformations, sorption and mineralization show the potential of both natural and engineered microor- ganisms as bioremedial tools. This review is to provide an overview of the application of radiation-resistant bacteria to decontamination of metal and radionuclide.展开更多
