Application of yeasts and yeast derivatives for the biological control of toxigenic fungi and their toxic metabolites

Abstract Mycotoxins, the metabolites of toxigenic fungi are important contaminants food and agriculture industry throughout world. Among different strategies to minimize mycotoxins synthesis decontamination food; yeasts their derivatives used as efficient biological control agents. In this study, cell walls (CW) six yeast strains; two commercial baking {Saccharomyces cerevisiae (Sc 1 Sc2)}, low-fermenting (Candida intermedia Lachancea thermotolerans), non-fermenting (Cyberlindnera jadinii Candida friedrichii) were explored inhibit A. flavus growth, aflatoxin (AF) remove from contaminated buffers (at pH 3, 5 7) milk. The volatiles showed a significant inhibitory effect on growth (up 79%) potential. highest binding activities Sc strains noted against ochratoxin A (92%), AFB2 (66%), AFG2 (59%) AFB1 (31%). lowest occurred at 7 respectively. On other hand, all CWs significantly (44%–54%) reduced M1 (AFM1) These results show clearly that (particularly Sc) can be biocontrol agents in or management mycotoxin contamination.
