Role of Biosorption in Environmental Cleanup

Abstract

Pollution has been the major problem since decades, destructing our environment and resources. Among all types of pollutions, heavy metal pollution is causing major threat to the biosphere. It is mainly resulted due to the release of Industrial wastes into the atmosphere. Industries follow various chemical procedures to remove harmful pollutants from the industrial effluents associated with various disadvantages as a result many eco-friendly techniques have come into light keeping due to the disadvantages of the chemical techniques. Biosorption of heavy metals by microbial cells has been recognized as a potential alternative to existing technologies for recovery of heavy metals from industrial waste. Present review focuses on the biosorption of different metals by different means which lead to the eco friendly clean up of the environment without causing any damage as such to the surroundings/ without the release of chemicals into the atmosphere, this article mainly deals with the biosorption of Fe, Cr (VI),U, Pb, Cu2+, Cd(II), Mn, Zn, Ni, Lanthanides, Ni and the role of this technique in cleaning up of the environment.
