[The fate of fusarium toxins in the course of the synthesis of bioethanol from contaminated grain].

By means of a modelling experiment we followed the fate of deoxynivalenol (DON) and zearalenone (ZEA) in the production of bioethanol from grain.The experiment has been performed at the 'Versuchs- und Lehranstalt für Brauerei in Berlin e.V.

[Investigations of basic feed quality: Mycotoxins on maize for silage 1997-2003].

Maize for silage purposes is investigated on Zeralenone (ZEA) and Deoxynivalenol (DON) in Saxony since 1997. About 45 samples from various regions of Saxony are analyzed every year. The occurrence of DON and ZEA was proved for 20 to 90% of all samples.

[Not Available].

98 wheet samples harvested in 1998 from three different experimental plots in saxony where investigated on the species of fusarium and the mycotoxins DON, ZEA and nivalenol (NIV). Analysis of DON was done by fast-Elisa-test and HPLC-MS. There was a good correlation between the two methods but a tendency of higher values determined by Elisa.

Cleanup procedure for monitoring chlorinated compounds in animal feed and crops.

A powerful cleanup procedure for determination of chlorinated pesticides and polychlorinated biphenyls (PCBs) in difficult agricultural matrixes like feeds or crops was developed to eliminate the interferences in chromatograms obtained by gas chromatography with electron capture detection. The adsorption material used was ENVI-Carb, a graphitized nonporous carbon material. This procedure proved to be more reliable than the established cleanup procedure, which uses gel permeation chromatography and silica gel cartridges.
