SUMMARY: As the Food and Agricultural Organisation of the United Nations (FAO) classified 25% of the world's crops contaminated with Fusarium and its intermediate catabolic products, a European Commission ((EC) No 856/2005) was consequent, in order to deal with the identified contaminates. This effects approximately 3.8 Mio. t/a (FAOstat, 2005). One of the commanding toxins produced from the indigenous population of moulds is Deoxynivalenol (DON). It is know to provoke detrimental health effects to living beings. Due to this, the most feasible, environmentally compatible and economical Option has to be revealed in order to get rid of the contaminated batches, which inspires current research at Hohenheim's State Institute of Farm Machinery and Farm Structures to create innovative routines of a save disposal. First findings of the running cooperative project prove the inactivation potential of biogas fermentation to either Fusarium (CFU), DON (Microbiological; Schollenberger, et al.) or DOM-1 (Microbiological; Schollenberger, et al.). Retention times of 0.5 days showed no proof of Fusarium spores after extraction and examination. A simultaneous and suitable production of biogas underlines the reahstic economic potential of this approach in the course of practical retention times and conditions of a fermentation process. Fermentation test series were carried out under varying parameters of temperature, infection rate and time of exposure in a bench-scale set-up.
