啤酒发酵中代谢工程的初步研究

Pilot Study of Metabolic Engineering in Beer Fermentation

将代谢工程理论应用于啤酒的发酵过程,通过构建啤酒发酵过程中酵母的代谢网络模型,对啤酒发酵过程进行代谢通量分析。研究不同压力下啤酒酵母代谢能力的变化,并对其进行了代谢通量分析,结果表明,高压可对酵母在啤酒发酵过程中的代谢产生一定的抑制作用。

The theory about metabolic engineering was applied in the beer fermentation, Through the construction of a network model of S.cerevisiae, the metabolic flux in beer fermentation was analyzed. Besides, the metabolic ability ofS, cerevisiae under different pressure was studied and its metabolic flux was also analyzed, The results suggested that high pressure could inhibit the metabolism in beer yeast fermentation.
