Abstract
In this paper enzymatic hydrolysis reactions have been considered as i ntegration-limited reactions analogous to crystal growth. Based on the mathematical formulation of diffusion of polysaccharide substrate mol ecules to binding sites of the enzyme, integration kinetics were deriv ed and compared to measured data. Significant is the measured and calc ulated decrease of the ratio of the specific activity and the Michaeli s-Menten parameter with increasing molar mass of the enzymes with an e xponent more than unity.
