Bioremediation

The conversion or degradation of toxic substance to less toxic substance or non-toxic substance by the use naturally occurring microorganism such as bacteria, yeast and fungi is known as Bioremediation. Bioremediation can be classified as in situ or ex situ. The treatment of contaminated soil or water at its location is known as in situ bioremediation. Whereas the excavation or pumping of contaminated soil or water before the treatment is known as ex situ bioremediation. Bioremediation can occur naturally or can be induced by the addition of Oxygen, fertilizers, etc., that will help in the growth of pollution-eating microbes. The involvement of plants in the bioremediation of pollutants is called as phytoremediation. The uses of various types of plants to destroy, remove, transfer and/or stabilize contaminants in the groundwater or soil is known as Phytoremediation.
