The pesticides pollution of soils has become one of the major environmental problems. However, enzymes such as peroxidase, parathion and hydrolase, which play a remarkable role in the bioremediation of pesticides polluted soils, can degrade parent compounds into less or no toxic metabolites through hydrolysis, oxidization, coupling reactions and so on. This approach is one of the best bioremediations of polluted soils with high efficient degradation, low cost and safety, by which the intermediate products of pesticides are incorporated into humus during the humification process, so that soils can restore dynamic balances.展开更多
