Minimoose Posted February 7, 2008 Share Posted February 7, 2008 Deinococcus radiodurans ("strange berry that withstands radiation", formerly called Micrococcus radiodurans) is an extremophilic bacterium, and is the most radioresistant organism known. While a dose of 10 Gy is sufficient to kill a human, and a dose of 60 Gy is sufficient to kill all cells in a culture of E. coli, D. radiodurans is capable of withstanding an instantaneous dose of up to 5,000 Gy with no loss of viability, and an instantaneous dose of up to 15,000 Gy with 37% viability. It can survive heat, cold, dehydration, vacuum, and acid, and because of its resistance to more than one extreme condition, D. radiodurans is known as a polyextremophile. It has also been listed as the world's toughest bacterium in "The Guiness Book Of World Records" because of its extraordinary resistance to several extreme conditions. It has been classified as a Gram-positive bacterium. Source I found this interesting :p Link to comment Share on other sites More sharing options...
