Notes:
A procedure to obtain the overall rate of hydrolysis of biopolymers is proposed, based on the fitting of the experimental data x = f(t) to cubic spline functions and from these, by differentiation, to obtain dx/dt. The values of these dx/dt slopes are an exclusive function of the conversion, x, when E0, S0, pH and temperature are constant. The fitting of dx/dt versus x leads to equations of the type \documentclass{article}\pagestyle{empty}\begin{document}$$\frac{{dx}}{{dt}} = a \cdot x\exp(- b \cdot x)$$\end{document} for the glucoamylase-starch system, where b = 8·75 and a = f(E0, T).
