Abstract

This work deals with the characterisation of trichothecene metabolites after the microbial degradation by the bacterial strain BBSH 797. Besides deoxynivalenol (DON), also the degradation of other trichothecenes was investigated. In the case of nivalenol, its metabolite deepoxy nivalenol could be identified. Useful methods for the structural characterisation are GC-MS or LC-PB-MS which were used in this particular case.

Zusammenfassung

In dieser Arbeit konnten erstmals Metaboliten anderer Trichothecene als Desoxynivalenol (DON) nach Biotransformation (durch den Bakterienstamm BBSH 797) identifiziert werden. Unter anderem konnte Nivalenoldeepoxid als Metabolit von Nivalenol identifiziert werden. Es konnte weiters gezeigt werden, daß GC-MS und die Kopplung LC-PB-MS für die Strukturaufklärung von Mykotoxinmetaboliten sehr gut geeignet sind.
