Toxin-producing fungi on feed grains and application of yeasts for their detoxification

The research deals with the contamination of feeding crops with fungi, producing mycotoxins and use of selected yeasts for detoxification. The thin-layer chromatography and ELISA methods were applied for the analysis of fungal secondary metabolites. The results showed a high rate of the grain contamination with fungi, mainly from genera Penicillium, Fusarium, Aspergillus and Alternaria. Some of the fungal strains produced 6-9 toxic compounds. The novelty of the study was the application of the yeast strains in detoxification of aflatoxins, zearalenon and deoxynivalenol in feed.
