Mean percentage conversion of deoxynivalenol (DON) to 3-acetyldeoxynivalenol (3ADON) for barley fermentations containing galactose. For each time point, the SEM is based on three replications. Note that the y axes have been scaled for each of the barley genotypes. Study was conducted for 66 hours and, subsamples were taken at 0, 20, 44 and 66 hours. For the comparison between the two trichothecene 3-O-acetyltransferases, the VA04B-125 mash samples were taken at 0 h, 23 h, 47 h and 71 hours. Mycotoxin extractions were performed on all subsamples and analyzed by gas chromatography/mass spectrometry.
