  1. The values represent the enzyme activity with starch and maltodextrins as substrates. The values in the parentheses represent the relative activity with its starch-hydrolyzing activity taken as 100%. Experiments were carried out in duplicate or triplicate, and the average values are indicated. *Not determined.
