Eventually which collected from the gut region of wild animals especially elephants. Fascination with these survivors Scientists have been fascinated by these tough bacteria for years. Deinococcus accomplishes its resistance to radiation by having multiple copies of its genome and rapid DNA repair mechanisms. 1973) Brook and Murray 1981 is one of currently 47 species in the genus Deinococcus within the family Deinococcaceae. The natural habitat of Deinococcus is not yet known because Deinococcus is chemoorganotrophic. D. radiodurans, Deinococcus geothermalis and Deinococcus deserti [3]. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. The bacterium Deinococcus radiodurans is a champion of extreme radiation resistance that is accounted for by a highly efficient protection against proteome, but not genome, damage. D. radiodurans survives irradiation by repairing DNA damage via an extremely efficient DNA repair system. Cells of deinococci are spherical or rod1 shaped [5]. At first glance D. radiodurans doesn't appear to possess any DNA repair genes that some other bacterium doesn't also have. It can survive cold, dehydration, vacuum and acid, and is therefore known as a polyextremophile, but it still cannot survive in anaerobic conditions.
