微生物降解苯甲酸的研究进展

Advances in benzoic acid degradation by microorganism

摘要:

苯甲酸在工业中的广泛应用使其成为环境中的常见污染物, 对微生物好氧降解苯甲酸的邻位途径、间位途径、龙胆酸途径和原儿茶酸途径及厌氧降解途径等进行总结, 并对苯甲酸降解过程中发挥重要作用的苯甲酸双加氧酶的种类、不同组分及苯甲酸降解基因和调控基因的基因簇进行介绍, 同时展望微生物降解污染物的发展方向。

Abstract:

Benzoic acid is becoming a common pollutant in the environment because of its widely use in industry. We summarized different pathways of the aerobic and anaerobic degradation of benzoic acid by microorganism. Both the two- and three-component benzoic acid dioxygenases play important roles in the process of benzoic acid degradation. Gene clusters of benzoic acid degradation and regulation were introduced, and also the direction of pollution degradation by microorganism in the future.
