Abstract:

Deoxynivalenol (DON), a secondary metabolite produced by Fusarium, is widely found in polluted grains
and animal feeds, which can cause severe losses to the global agricultural economy as well as potential threats to human
and animal health. The physical and chemical treatments mainly used to control DON are limited by their disadvantages.
Recently, the microbial biotransformation method has shown a promising future in DON control in cereals. This paper
outlines the basic chemical properties and toxicity of DON and recent progress in developing biological detoxification
methods, with the aim of providing theoretical basis for the microbial control of DON in foods and feeds.

Key words: deoxynivalenol, toxicity, adsorption, biodegradation, degradation mechanism
