不同代数酿酒酵母发酵产酶酶活力变化研究

Study on the Change of the Activity of Enzymes Produced by Saccharomyces Cerevisiae of Different Generation

通过对不同代数酿酒酵母发酵产酶酶活力测定分析,研究酶活力变化与酵母代数的关系。结果表明,随着酵母代数的增加,产蛋白酶活力逐渐增强,产蔗糖酶和脂肪酶活力逐渐减小。

The relations between enzyme activity change and S.cerevisiae generation were investigated through the measurement of the activity of enzymes produced by S.cerevisiae of different generation.The results suggested that with the increase of S.cerevisiae generation,the activity of the produced protease improved gradually,however,the activity of the produced invertase and lipase decreased gradually.
