Abstract
Deinococcus Radiodurans is known for its exceptional tolerance potential against ionizing radiation, an unusual trait not found in any other bacterium. Radiation induced DNA damage in Deinococcus Radiodurans seems, by all accounts, to be repaired through the involvement of enzymatic components i.e., RecA that cleaves and splice together the overlapping chromosomal fragments through homologues recombination. This swift mechanism of DNA repairing in these bacterium’s accounts for their survival under extreme conditions and also their utilization in bioremediation of heavy metals such as Deinococcus Radiodurans assisted biofilms involved in the bioremediation of nickel and cobalt metals.
