Insight into Yeast-Mycotoxin Relations

Fungal mycotoxins are secondary metabolites that can be present in green forage, hay, or silage. Consumption of contaminated plants or agricultural products can cause various animal and human diseases, which is why problems associated with mycotoxins have received particular attention. In addition, public pressure to produce healthy food and feed is also increasing. As the results of several surveys indicate that yeasts can decrease toxic effects by binding or converting secondary metabolites or control growth of harmful fungi, this article provides an overview of the yeast species that can have great potential in detoxification. The most important antagonistic yeast species against toxigenic fungi are described and the mode of their inhibitory mechanisms is also discussed. We provide an insight into toxin binding and biotransformation capacities of yeasts and examples of their use in silo. Issues requiring further study are also mentioned.

Automated summary

Fungal mycotoxins, as secondary metabolites, can cause various animal and human diseases when consumed through contaminated plants or agricultural products. Yeasts have the potential to decrease toxic effects by binding or converting secondary metabolites. The most important antagonistic yeast species against toxigenic fungi are discussed, along with their inhibitory mechanisms. The capacity of yeasts for toxin binding and biotransformation, as well as their use in silage, is also highlighted. Further research is needed in this area.
