Functional Modification of yeasts to minimize the production of ethyl carbamate modified by urea Transporter Expression

摘要

Under fermentation conditions, the product and process can reduce the concentration of ethyl carbamate to the fermented beverage or food. The yeast system used is transformed to express urea transmitter, which actively transports urea in yeast cells, such as dur3. Yeast can also be modified to express degrading enzyme activity of intracellular urea under fermentation conditions, such as dur1.2. ADEM s has a modified yeast strain to reduce nitroglycerin taste suppression of a urea transporter gene expression,A method of changing yeast strains under fermentation conditions for the production of fermented beverages or foods. Use of ECA to provide fermented beverages and fermented beverages or food.
