酵母细胞壁对葡萄酒中酵母发酵代谢的影响

摘要

Yeast cell wall, also called yeast hulls, has become one of the most important auxiliary materials in grape wine-making due to its unique physiological activities. In this study, yeast hulls was added during the fermentation of grape wine to investigate its effects on yeast growth& metabolism. The results suggested that yeast hulls could significantly promote the growth and the reproduction of yeast, and the addi-tion of yeast hulls in grape juice containing alcohol could reduce the inhibition and the toxication of ethanol on yeast and promote the physio-logical activities and the growth and the metabolism of yeast.
