Deinococcus Radiodurans: The World's Toughest Bacterium. A Review

Deinococcus Radiodurans is the “world’s toughest bacterium” as per the Guinness book of world record. It is the most radiation-resistant bacterium ever known. It can withstand severe dehydration, cold, vacuum, acid,lack of nutrition, and survive to the radiation dose, a fraction of which is sufficient to kill the human being. The meaning of its name is 'strange berry that withstands radiation.’ This remarkable talent is extensively studied by the biologist and scientist to find out how it survives the extreme life-threatening conditions. This knowledge is being used to find out the means to survive in radiation exposure and also to handle toxic waste.
