The Fusarium contaminated wheat grains which contain DON negatively affect the fermentation process and reduce the ethanol concentration by 13.5% in the fermented broth; after alcoholic fermentation 73% of the initial DON level could be detected in DDGS. The created complex of enzyme preparation containing xylanase from Trichoderma reesei (200 XU/100 g grains) increased the efficiency of the fermentation process of Fusarium contaminated wheat: the ethanol concentration increased by 35.3%. The reduction of the levels of DON up to 51.5% of the initial degree of contamination was achieved during the alcoholic fermentation process of Fusarium contaminated wheat grain with a high concentration of DON (3950 microgram/kg).
