Abstract: Abstract：Atrazine is a triazine herbicide，which can control annual monocotyledon and dicotyledon weeds，and also inhibit certain perennial weeds．It is one of the most important herbicides for corn production in the world．It can also be used in sorghum，sugarcane，fruit trees，etc．It is moderately persistent in the environment and can remain in the atmosphere，water，and soil environment．It is easy to cause different degrees of pesticide damage to subsequent crops such as rape，Chinese cabbage，fi eld mustard，cucumber，pepper，cowpea，and okra．At the same time，it causes harm to natural ecosystems and human health．This paper reviewed the microbial degradation of atrazine；introduced the microbial degradation techniques of herbicide atrazine from 3 aspects，including bioaugmentation，biostimulation，and immobilization；compiled and summarized the microbial groups being confi rmed in previous studies；clarifi ed the microbial degradationmechanism of atrazine from 2 aspects：degradation process and degradation genes；analyzed the factors affecting the microbial degradation of atrazine and prospected the future research direction．

摘要： 摘 要：阿特拉津为三嗪类除草剂，可以控制一年生单子叶和双子叶杂草，也可以抑制某些多年生杂草，是世界上玉米生产中最重要的除草剂之一，还可用于高粱、甘蔗、果树等。其在环境中具有中等持久性，可在大气、水体、土壤环境中残留，易对下茬作物，如油菜、普通白菜、菜薹、黄瓜、辣椒、豇豆、秋葵等造成不同程度的药害，对自然生态系统和人体健康造成危害。本文就阿特拉津的微生物降解展开综述，从生物强化、生物刺激、固定化微生物技术3 个方面介绍了除草剂阿特拉津的微生物降解技术，整理归纳了以往研究中证实的可以降解阿特拉津的微生物类群，从降解过程、降解基因两个方面阐明了阿特拉津的微生物降解机制，分析了影响阿特拉津微生物降解的因素，并对未来的研究方向进行了展望。
