The Commission Regulation (EC) No 856/2005 [1] sets maximum levels of pollutants in foodstuffs. Consequently Fusarium spores within cereals are defined problematic and to get rid of in future. This inspires current research to create innovative routines of a save disposal. One pressing research approach at the University of Hohenheim is to investigate the prerequisites of a potential deactivation of Fusarium spores in a biogas process. A subsequent reduction of the contained mycotoxin (Deoxynivalenol) throughout the fermentation process is desired. Varying parameters of temperature, infection rate and time created surrounding conditions which performed a convenient potentiality of spore deactivation. The process is attended by a simultaneous production of biogas. This appears as an alternative way of disposal creating clean high grade energy simultaneously. For Germany an infected quantity of approximately 3.8 Mio. t/a at a sixfold higher annual yield of cereals (FAOstat, 2005) are potential to be decontaminated adapting the promising approach.
