Mathematical Analysis of a Kinetic Model for Enzymatic Cellulose Hydrolysis

Biofuel production such as ethanol from lignocellulosic biomass consists of three fundamental processes: pretreatment, enzymatic hydrolysis, and fermentation. Enzymatic hydrolysis uses two types of enzymes simultaneously: endoglucanase I (EG1) and cellobiohydrolase I (CBH1), to break the cellulose c...

description Biofuel production such as ethanol from lignocellulosic biomass consists of three fundamental processes: pretreatment, enzymatic hydrolysis, and fermentation. Enzymatic hydrolysis uses two types of enzymes simultaneously: endoglucanase I (EG1) and cellobiohydrolase I (CBH1), to break the cellulose chains into sugar in the form of cellobiose or glucose.
