中文摘要:
      二硝基苯胺类除草剂是一类广谱、高效且广泛使用的除草剂,微生物的降解代谢作用是其在环境中消解的最主要因素。分离筛选除草剂的高效降解菌株、分析其降解途径并阐明其微生物降解机制,可为除草剂残留污染的微生物降解修复提供理论依据和优良的降解菌株、降解基因和酶资源。本文简述了二硝基苯胺类除草剂的微生物降解菌株、降解代谢途径和降解基因/酶的研究进展,为进一步研究该类除草剂的微生物降解及其污染生物修复提供理论依据和资源。
英文摘要:
      Dinitroaniline herbicides are a class of highly efficient pre-emergence herbicides, with broad spectrum and wide application. Microbial catabolism plays the most important role in the dissipation of the dinitroanilines in the environment. Isolating highly efficient herbicides-degrading microorganisms, studying the metabolic pathways, and elucidating the degradation mechanisms will provide the theoretical basis and degrading resources for the study on the transformation mechanism and ecological security of the herbicides in the environment, and for the microbial remediation of the herbicides residual contamination in the environment. This paper summarizes the research progress on microbial degradation of dinitroaniline herbicides, including degrading bacteria, metabolic pathways, and the genes/enzymes involved in the degrading progress. The aim of this review is to provide theoretical basis and resources for the bioremediation of dinitroaniline herbicides residual contamination in environment.
