Application of microorganisms in decontaminating radioactive wastes

Abstract:   (11609 Views)
Radioactive wastes are inevitably produced in the course of radioactive activities. In the years 1945 to 1986 and while nuclear weapons were mass produced, high levels of radioactive waste were left over on the surface of the Earth. Unfortunately these wastes spread easily which is due to their solubility in underground waters. Recently biologic techniques are used to eliminate or deactivate radioactive wastes. Microorganisms such as Deinococcus radiodurans, are very well suited for reducing costs and have high effectiveness in eliminating or deactivating this waste, a method named bioremediation. Deinococcus radiodurans, are gram positive non-spore and usually non-pathogen bacteria. they also contain red colored pigments resulting in pink colored colonies. These bacteria were first observed in cans which had been sterilized using radiation.
Keywords: bioremediation, radioactive wastes, Deinococcus radiodurans
