实验方案
To measure pectinase activity, a titrimetric stop reaction assay is used. One unit of pectinase will liberate 1 μmol of galacturonic acid from poly-galacturonic acid per hour at pH 4.0 at 25 °C.
在测定果胶酶活性时，使用了一种滴定终止反应法进行测定。在25 °C、pH 4.0条件下，一个单位的果胶酶每小时可从多聚半乳糖醛酸释放1 μmol 的半乳糖醛酸。
本操作程序可用于使用淀粉作为底物测定淀粉葡萄糖苷酶的活性。
This procedure may be used for the determination of Amyloglucosidase activity using starch as the substrate.
