微生物降解1,2,4-三氯苯研究进展

摘要

1,2,4-三氯苯(1,2,4-TCB)的微生物降解机制包括好氧降解、还原脱氯和共代谢。本文简要综述了国内外对1,2,4-TCB微生物降解方面的研究进展,分析了其微生物降解的可行性,讨论了其好氧降解的微生物种类以及降解途径,阐述了厌氧条件下,混合菌群以及纯菌株对1,2,4-TCB还原脱氯的过程,目的是为1,2,4-TCB污染土壤的微生物修复提供依据。%The mechanism of microbial degradation of 1,2,4-trichlorobenzene includes aerobic degradation, reductive dechlorination and co-metabolism. This paper provided a brief review of the research progress in the biodegradation of 1,2,4-TCB. The potential biodegradability was analyzed. The pathway of aerobic degradation of 1,2,4-TCB and the related microbial strains, as well as the reductive dechlorination of 1,2,4-TCB by microbial community or single strain were discussed. The aim of this paper is to provide a guide for microbial remediation of 1,2,4-TCB contaminated soil.
