Deinococcus radiodurans is a red-pigmented, radiation-resistant bacterium. It was first isolated from a radiation-sterilized can of corned beef in 1956.The bacterium has robust DNA repair mechanisms that enable it to withstand extreme environmental conditions, such as radiation 1000-times greater than the lethal dose for humans. The genome contains multiple chromosomal copies, which also contribute to its efficient repair abilities. In an one-year exposure experiment, the bacterium survived outside the International Space Station (low Earth orbit) without exhibiting morphological damage. In addition to research, the bacterium may have applications for bioremediation.
