Process of Bioremediation

Xiongwen Chen

Bioremediation is a method of treating polluted media, such as water, soil, and subsurface material, by modifying environmental conditions to encourage the growth of microorganisms that degrade the pollutants. The majority of bioremediation processes include oxidation-reduction reactions, in which an electron acceptor (usually oxygen) is added to induce the oxidation of a reduced pollutant (e.g., benzene). Additional nutrients, vitamins, minerals, and pH buffers can be applied to each of these methods to boost the microorganisms' conditions.
