三唑类农药的微生物降解研究进展

三唑类农药是一种广泛使用的防治植物病害的杀菌剂和植物生长调节剂，可通过抑制麦角甾醇的合成阻碍病原菌的细胞壁形成，从而起到防治作物病害的作用，也能抑制植物赤霉素合成延缓植物生长；但因大范围应用及其难以降解的特性，污染环境和影响人类健康。为给三唑类农药的微生物降解提供参考，基于文献研究，梳理总结了三唑类农药降解菌的种类、影响降解的环境因素和降解机理方面的研究进展，明确了微生物在不同环境中能有效降解三唑类农药，微生物降解技术有望应用于治理三唑类农药造成的环境污染。

Research Progress on Microbial Degradation of Triazole Pesticides

Triazole pesticides are widely used as fungicides and plant growth regulators, which can inhibit the synthesis of ergosterol to prevent the formation of cell walls of pathogenic bacteria, thereby, they play a role in crop disease control and can also inhibit the synthesis of plant gibberellin to delay the plant growth. However, because such fungicides are widely used and difficult to degrade, which pollute the environment and affect human health. In order to provide reference for the microbial degradation of triazole pesticides, the types of degrading bacteria to triazole pesticide degradation, environmental factors affecting degradation, and research progress on degradation mechanisms are summarized in this paper. It is clarified that micro-organisms can effectively degrade triazole pesticides under different condition, and microbial degradation technology is expected to deal with environmental pollution caused by triazole pesticides.
