DDT微生物降解研究

Research on DDT Microbial Degradation

DDT属于有毒物质,具有高残留、难降解等特性,是重要的环境污染源,而微生物降解是去除DDT污染的有效且环保的方法。本文简要综述了微生物降解DDT的研究进展,包括降解DDT所需的微生物、DDT的微生物降解机理,论述了影响DDT微生物降解的因素,研究了单株DDT降解菌的筛选,分析了降解土壤中DDT的新方法——植物-微生物联合修复法。

DDT is a toxic substance with high residues,difficult to degrade and other characteristics,is an important source of environmental pollution,and microbial degradation is an effective and environmentally friendly method to remove DDT pollution.This paper briefly summarizes the research progress of microbial degradation of DDT,including the microorganisms required to degrade DDT and the microbial degradation mechanism of DDT,discusses the factors that affect the microbial degradation of DDT,studies the screening of individual DDT-degrading bacteria,and analyzes a new method of degrading DDT in soil,namely plant-microorganism joint repair method.
