In this paper we study the kinetics of enzymatic hydrolysis of cellulose samples with different structural characteristics of. Found that with increasing crystallinity of cellulose samples speed the process of enzymatic hydrolysis decreases. For the analysis of the kinetic curves were used topochemical Avrami equation – Kolmogorov – Erofeev (AKE). Kinetic parameter n Calculations have shown that the rate of enzymatic hydrolysis of cellulose samples with a high degree of crystallinity is determined by diffusion of the enzyme molecules into the cellulosic substrate. With the decrease of the crystallinity degree of cellulose contribution of diffusion decreases, while the contribution to the total kinetic rate of hydrolysis increases.
