Abstract: (15397 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. |
