Ethanol from lignocellulosic materials enzymatic hydrolysis

Taherzadeh MJ, Karimi K. (2007b). Enzymatic-based hydrolysis processes for ethanol from lignocellulosic materials a review. Bioresources, 2, 707-738. 

The production of fuel ethanol from renewable lignocellulosic material ("bioethanol") has the potential to reduce world dependence on petroleum and to decrease net emissions of carbon dioxide. The lignin-hemicellulose network of biomass retards cellulose biodegradationby cellulolytic enzymes. To remove the protecting shield of lignin-hemicellulose and make the cellulose more readily available for enzymatic hydrolysis, biomass must be pretreated (1).
