In present work we investigated the antagonistic effect by S. cerevisiae against several wine-related microbial species vis-à-vis the secretion of antimicrobial peptides (AMPs).
The yeast Dekkera/Brettanomyces bruxellensis can cause enormous economic losses both in wine industry and fuel-ethanol processes due to production of phenolic off-flavour compounds and low ethanol productivities. In winemaking this microbial hazard is usually tackled by the use of chemical preservatives such as sulphur dioxide. In spite of this, D. bruxellensis strains are frequently found in wines at low level...
