Deoxynivalenol(DON)is a toxic secondary metabolite produced by Fusarium,which mainly infects wheat,corn and other grains.It not only causes huge economic losses to the agricultural industry,but also has a potential threat to human and animal health.Therefore,how to efficiently remove DON from grains has always been an urgent problem.Currently,there is good development space in terms of cost and large-scale promotion of the use of microorganisms and their metabolites for biological detoxification of DON.This article makes a detailed description of the harm and detection technology of DON,as well as the research and application of the detoxification mechanism of DON by lactic acid bacteria in recent years,which provides a reference for the biological pest control of DON in grains and feedstuffs by lactic acid bacteria and its large-scale industrial application.
