Bioremediation - An Important Tool to Conserve the Green Earth

Abstract

Use and overuse of resources have caused its depletion which in turn is creating a havoc to the environment releasing contaminants and pollutants in the atmosphere. Hazardous chemicals and toxic substances are accumulated in the nature harming the biological diversity. Bioremediation is a process that helps degrading contaminants using biological agents like, bacteria, algae, fungi, yeast and plants. Through recombinant DNA technology, breeding line-ups and genetic modification methods, biotechnology was able enhance the natural properties of plants to make it more suitable as per the environmental conditions. Beneficial microbiological agents are used to treat contaminated culture water or waste water which utilizes contaminants as their energy sources. Use of microbes as biocontrol agent is risky; however, at critical times it was proved to be helpful.
