Herbicides are released to the environment with potential ecotoxicological risks for mammals. Yeastis a good model to elucidate toxicity mechanisms. We investigated how three commercial herbicides(Proper Energy, Pointer, and Silglif) and their active ingredients (respectively, fenoxaprop-P-ethyl,tribenuron methyl, and glyphosate) can affect biological activities of an oenological Saccharomycescerevisiae strain, which may be resident on grape vineyards of the same geographical areas whereherbicides are used. The use of commercial grade herbicides employed in Italy allowed us to reproducethe same conditions applied in crops; at the same time, assaying pure single active compoundsmade it possible to compare the effects obtained with commercial formulations. Interestingly, wefound that while pure active compounds affect cell growth and metabolism at a lower extent,commercial preparations have a significant major negative influence on yeast biology.Keywords: Pesticides; herbicides; ecotoxicity; wine yeast
