Abstract:The key issue for the industrialization of cellulosic ethanol is the conversion of lignocellulosic feedstocks into fermentable sugars. Enzymatic hydrolysis of lignocellulose has caught much attention because of its modest reaction conditions, fewer by-products and environmental benignity. A lot of chemical and biochemical technologies are developed to enhance the efficiency of lignocellulose hydrolysis or to reduce the cost of cellulase. In this paper, the effects of pretreatment methods, highly efficient enzyme mixtures, recycling of enzyme, integrated technologies and high solid substrate concentration on the efficiency of lignocellulose conversion are reviewed in details. The progress and prospects on enzymatic hydrolysis of lignocellulosic materials are also presented. Contents
