Almost every crop supports an indigenous population of moulds. Examining various occurrences, it appears that the most significant plant pathogenic fungus is Fusarium. The Food and Agricultural Organisation of the United Nations (FAO) classified 25% of the world's crops as contaminated with these catabolic products. Fusarium spores can therefore be regarded as problematic and should be inactivated within cereals. Consequently, the European Commission issued a legal Regulation ((EC) No 856/2005 [1]), which sets maximum levels of pollutants in foodstuffs. In order to achieve this, the regulation requires the disposal of affected wheat. Therefore, the most feasible, economical and environmentally sound Option for the disposal of contaminated batches is to be sought. This inspired current research to create new, innovative and safe methods of disposal. One pioneering research approach at the University of Hohenheim is the investigation of the prerequisites for the Potential deactivation of Fusarium spores by fermentation. The project is founded by the German FNR (Agency for renewable resources).A subsequent reduction of the contained Mycotoxin (DON) and a deactivation of the fertile parts of Fusarium throughout the process is prospective. Method: Hohenheim Biogas Yield Test (HBT). Due to the physiological character of rumen, it is capable of inactivating or transforming amounts of DON by means of the contained infusoria (KING et. al., 1984 If the microbiological environment of rumen provides a good basis for the process of deactivation, the respective micro organisms are proposed to be found in manure as well. Proving a potential respective Biogas production, determination of the resulting methane yield of the specimens is imperative and carried out by the HBT. One of the trials determining microbiological activity rate is characterised by the fermentation of wheat at different levels of contamination (6.700ug/kg, 20.000ug/kg, and 46.100ug/kg). The .....
