Progress of Bioremediation of Organophosphate / 中国生物工程杂志

ABSTRACT

Now organophosphorus pesticides (OPs) bioremediation mainly means microbial bioremediation. However, phytoremediation has an advantage over microbial bioremediation because phytoremediation is safer and costs less than microbial bioremediation. Nevertheless, phytoremediation has limitations yet such as plants need better growth conditions and the efficiency of phytoremediation is lower. All these have confined the application of phytoremediation. Progresses of microbial bioremediation and phytoremediation of OPs were reviewed and OPs degrading enzymes and their organism sources, which are known by now, were summarized. Moreover, there are five important ways to enhance the efficiency of phytoremediation of OPs. They are culling plants, studying the action between soil and OPs, studying the genes that can resist or get rid of OPs, setting up the combined system of microbial bioremediation and phytoremediation and using degrading enzymes secreted selectively by roots.
