摘要：
Deoxynivalenol (DON) transformation products from selected time course experiments were analyzed by thin-layer chromatography. With the strainAlternaria alternata f. sp.lycopersici AS27-3, one major metabolite of DON in ethyl acetate was observed. This unidentified metabolite was more polar than DON and has a Rf value of 0.71. Derivatization indicated that this metabolite was probably an unidentified trichothecene. Screening of 29 other microbial isolates (bacteria, yeast, filamentous fungi) for DON transformation did not result in any active organism.
