Wine Spoilage Control: Impact of Saccharomycin on Brettanomyces bruxellensis an...
Branco, Patricia; Coutinho, Rute; Malfeito-Ferreira, Manuel; Prista, Catarina; Albergaria, HelenaABSTRACT: The yeast Brettanomyces bruxellensis is one of the most dangerous wine contaminants due to the production of phenolic off-flavors such as 4-ethylphenol. This microbial hazard is regularly tackled by addition of sulfur dioxide (SO2). Nevertheless, B. bruxellensis is frequently found at low levels (ca 10(3) cells/mL) in finished wines. Besides, consumers health concerns regarding the use of sulfur dioxi...

Branco, Patrícia; Coutinho, Rute; Malfeito-Ferreira, Manuel; Prista, Catarina; Albergaria, HelenaThe yeast Brettanomyces bruxellensis is one of the most dangerous wine contaminants due to the production of phenolic off-flavors such as 4-ethylphenol. This microbial hazard is regularly tackled by addition of sulfur dioxide (SO2). Nevertheless, B. bruxellensis is frequently found at low levels (ca 103 cells/mL) in finished wines. Besides, consumers health concerns regarding the use of sulfur dioxide encourage...
Dominance of Saccharomyces cerevisiae in wine fermentations: secretion of antim...
Albergaria, Helena; Branco, Patricia; Francisco, Diana; Coutinho, Rute; Monteiro, Margarida; Malfeito-Ferreira, Manuel; Arneborg, NilsIn 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).

Saccharomyces cerevisiae and Dekkera bruxellensis interactions in alcoholic fer...
Coutinho, Rute; Branco, Patricia; Monteiro, Margarida; Malfeito-Ferreira, Manuel; Albergaria, HelenaThe 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...
