Abstract

Biofuel production such as ethanol from lignocellulosic biomass consists of three fundamental processes: pretreatment, enzymatic hydrolysis, and fermentation. Enzymatic hydrolysis breaks the cellulose chains into sugar, for example, cellobiose and glucose. The kinetics of the enzymatic hydrolysis of cellulose depends mainly on three factors: 1) the nature of the cellulolytic enzyme employed, 2) the structure of cellulose, and 3) the mode of interaction between the enzyme and cellulose molecules. Cellulose depolymerization by EG and CBH enzymes is modeled using population-balance equations which employ continuous distributions to the evolution of the spectrum of chain lengths. The theoretical and mathematical development needed to describe the enzymatic hydrolysis of insoluble cellulose chains embedded in a solid particle by EG and CBH enzymes will be presented.
