Kinetic expression for maltose production from soluble starch by simultaneous use of β‐amylase and debranching enzymes

Abstract

The kinetics of the hydrolysis of soluble starch by simultaneous use of beta-amylase and either isoamylase or pullulanse was studied experimentally for a wide range of subtrate and enzyme concentrations. A kinetic expression was constituted for maltose production by beta-armylase, which was stimulated by an increase in linear linkage portions due to the debranching enzyme on amylopectin molecules. As a result, calculations by the kinetic expression agreed with time course data under various conditions.
