 Title    Biosynthesis of Trichothecene My cotoxins in Fusarium culmorum Cultures  
 Abstract    A high yielding production of the trichothecene mycotoxin 3-acetyldeoxynivalenol (3-AcDON) in cultures of Fusarium culmorum is described. By supplying [14C]acetate, 14C-labelled 3-AcDON suitable for further metabolic studies has been obtained. The pattern of labelling has been ascertained by using 13C-labelled acetate precursors, and is in line with established biosynthetic data. A second trichothecene produced in significant amounts by F. culmorum has been identified as 3a, 15-diacetoxy-7a, 8a-dihydroxy-12, 13-epoxytrichothec-9-ene (7a, 8 a-dihydroxycalonec-trin).

 Title    Metabolie Conversions of Trichothecene Mycotoxins: Biotransformation of 3-AcetyldeoxynivaIenoI into Fusarenon-X  
 Abstract    The trichothecene mycotoxin 3-acetyldeoxynivalenol was transformed by cultures of the diace-toxyscirpenol producer Fusarium sp. strain C37410-90 into four compounds, identified as deoxy-nivalenol, 15-acetyldeoxynivalenol, 3,15-diacetyldeoxynivalenol and fusarenon-X. The major transformations are the result of specific esterification and de-esterification processes, but the production of fusarenon-X involves in addition a novel 4ß-hydroxylation of the trichothecene ring system itself.
