Study of Radioresistance and Bioremediation using Radio-Resistant Bacteria

Swapnamay Banerjee

Abstract: Nature has always produced variety of life forms, adapted to survive in varieties of environmental conditions. Even in harshest of conditions, where most of the life forms are thought to be killed, life still exists. While exploring these 'extremophiles', a number of living organisms have been found to be excellently radio-tolerant. Their existence and their survival mechanism are of great significance as it paves the way for their application in various biotechnological aspects including bioremediation of nuclear pollutants. In this review, we shall try to put focus on origin and diversity of radiation-resistant bacteria as well as the various selective mechanisms by which microorganisms can sustain in radiation rich environment. Also, we shall try to spot out how these radioresistant bacteria help in nuclear waste clean-up, as they cannot be mobilized easily, and also, they have a long decay period, which makes them difficult to remediate where radionuclides (particularly plutonium and uranium) have been used and/or produced as a by-product.
