Low Phenotypic Penetrance and Technological Impact of Yeast [ ] Prion-Like Elements on Winemaking.

[ ] prion-like elements partially relieve carbon catabolite repression in . They have been hypothesized to contribute to wine yeast survival and alcohol level reduction, as well as communication with bacteria and stuck fermentation. In this work, we selected [ ] derivatives from several genetic backgrounds.

Identification of target genes to control acetate yield during aerobic fermentation with Saccharomyces cerevisiae.

Background: Aerobic fermentation of grape must, leading to respiro-fermentative metabolism of sugars, has been proposed as way of reducing alcohol content in wines. Two factors limit the usefulness of Saccharomyces cerevisiae for this application, the Crabtree effect, and excess volatile acidity under aerobic conditions. This work aimed to explore the impact on ethanol acetate production of different S.
