摘　　要：Salicylate is a type of pollutant widely and persistently existed in environ- ment. Microbiological degradation of salicylate as one kind of biological remediation methods has the advantages of low cost, good effect and no secondary pollution, and also attracts wide attention both at home and abroad. Currently, many salicy- late-degrading bacteria are isolated and screened, while the molecular mechanism of salicylate metabolism is also worth deep research. The research about molecular mechanism of microorganism degradation was overviewed, various degrading path- ways including catechol meta-cleavage pathway and gentisate pathway were intro- duced, and the latest progress in regulating genes of salicylate degradation was summarized.水杨酸是一类广泛存在于环境中并持续存在的污染物,微生物降解水杨酸作为生物修复的一种,具有费用低、效果好、无二次污染的优点,获得国内外广泛研究。目前,大量水杨酸降解菌获得分离和筛选,而水杨酸代谢的分子机制也得到了深入研究。对微生物降解水杨酸的分子机制研究进展进行了概述,介绍了儿茶酚间位裂解途径、龙胆酸途径等多种水杨酸降解途径,以及参与水杨酸降解的调控基因的最新研究进展。
