Bioremediation by microorganisms like candida species

Pinar Sanlibaba

Bioremediation is a process used to treat contaminated media, including water, soil and subsurface material, by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants. In many cases, bioremediation is less expensive and more sustainable than other alternatives. Biological treatment is a similar approach used to treat wastes including wastewater, industrial waste and solid waste. Most bioremediation processes involve oxidation-reduction reactions where either an electron acceptor (commonly oxygen) is added to stimulate oxidation of a reduced pollutant (e.g. hydrocarbons) or an electron donor (commonly an organic substrate) is added to reduce oxidized pollutants (nitrate, , oxidized metals, chlorinated solvents, explosives and propellants).
