The Commission Regulation (EC) No 856/2005 Sets maximum levels of pollutants in foodstuffs. Consequently Fusarium spores within cereals are problematic and to be inactivated in the given context. This inspires current research to create innovative routines of a save disposal. One pioneering research approach at the State Institute of Farm Machinery and Farm Structures in cooperation with the Institute of Animal Nutrition is to investigate the prerequisites of a potential deactivation of Fusarium spores in a fermenting process. Anaerobic digestion as a biological process involves the conversion of complex organic feedstuffs into a range of smaller, simpler compounds under non attendance of Oxygen. The use of digester effluent and residue as a fertiliser after the biogas process is, for the farmer, a very important factor in the calculation of the economic viability of this System [2]. However, the fertiliser value is not the only factor which needs to be considered before the effluent can be applied to arable lands. The presence or absence of any undesirable organisms must also be taken into account [2]. The fate of phytopathogenic organisms in anaerobic digestion har only been reported by these aforementioned authors although their great importance in digester Systems fed with plant waste materials. The test agreement was accommodated follows: Isolated Fusarium culmorum spores (FC 46) were derived from a beta testing received from the State Plant Breeding Institute were dissolved and added into the established Hohenheim Biogas yield test after VDI Guideline (VDI 4630, [1]). The results show that no vital spores could be detected after a retention time of 3.5 hours. This points out an encouraging sign for the use of anaerobic digestion for the treatment of infected plant material.
