Metabolism of the Fusarium mycotoxins zearalenone and deoxynivalenol by yeast strains of technological relevance.
The Fusarium mycotoxin zearalenone (ZEA), added at a level of 2 micrograms/ml, was reduced stereoselectively by cultures of Candida tropicalis, Torulaspora delbrückii, Zygosaccharomyces rouxii, and 7 Saccharomyces strains to both alpha- and beta-zearalenol. In contrast, only alpha-zearalenol was produced from ZEA by Pichia fermentans and several yeast strains of the genera Candida, Hansenula, Brettanomyces, Schizosaccharomyces, and Saccharomycopsis. No glucose conjugates of ZEA (zearalenone-4-beta-D-glucopyranoside) were detected. The trichothecene mycotoxin deoxynivalenol (DON) was not metabolized by any of the yeast strains that were used for analysis.
