Yeast ATF2 Gene Expression and Wine Aroma: Wine Production and Agent-Based Modeling Approach Public
Downloadable Contentopen in viewer
Ester compounds yield enjoyable fruity aromas in wine. The ATF2 gene in yeast encodes the AAT enzyme, which catalyzes the ester production reaction in wine fermentation. We varied fermentation conditions and measured ATF2 expression levels and ester production. Although no specific condition increased ester production, we found conditions that created notable wine aroma profiles. Furthermore, we investigated how ATF2 gene is structurally related across various yeast strains, and developed an agent-based simulation that demonstrates the molecular interactions in wine fermentation.
