Strobilurin fungicides have been widely used in agricultural fields for decades. These pesticides are designed to manage fungal pathogens, although their broad-spectrum mode of action also produces non-target impacts. Therefore, the removal of strobilurins from ecosystems has received much attention. Different remediation technologies have been developed to eliminate pesticide residues from soil/water environments, such as photodecomposition, ozonation, adsorption, incineration, and biodegradation. Compared with conventional methods, bioremediation is considered a cost-effective and ecofriendly approach for the removal of pesticide residues. Several strobilurin-degrading microbes and microbial communities have been reported to effectively utilize pesticide residues as a carbon and nitrogen source. The degradation pathways of strobilurins and the fate of several metabolites have been reported. Further in-depth studies based on molecular biology and genetics are needed to elaborate their role in the evolution of novel catabolic pathways and the microbial degradation of strobilurins. The present review summarizes recent progress in strobilurin degradation and comprehensively discusses the potential of strobilurin-degrading microorganisms in the bioremediation of contaminated environments.
几十年来，甲氧基丙烯酸酯类杀菌剂一直在农业领域广泛使用。这些农药旨在控制真菌病原体，尽管它们的广谱作用模式也会产生非目标影响。因此，从生态系统中去除甲氧基丙烯酸酯类杀菌剂受到了广泛关注。人们已经开发出不同的修复技术来消除土壤/水环境中的农药残留，如光分解、臭氧化、吸附、焚烧和生物降解。与传统方法相比，生物修复被认为是一种去除农药残留的经济有效且环保的方法。据报道，几种降解甲氧基丙烯酸酯类杀菌剂的微生物和微生物群落能够有效地将农药残留作为碳源和氮源加以利用。甲氧基丙烯酸酯类杀菌剂的降解途径以及几种代谢产物的归宿已有报道。需要基于分子生物学和遗传学进行更深入的研究，以阐明它们在新的分解代谢途径进化以及甲氧基丙烯酸酯类杀菌剂微生物降解中的作用。本综述总结了甲氧基丙烯酸酯类杀菌剂降解的最新进展，并全面讨论了降解甲氧基丙烯酸酯类杀菌剂的微生物在污染环境生物修复中的潜力。
