This volume summarizes our current knowledge on different biomass-converting enzymes and their potential use in converting biomass into simple sugar to generate bioenergy and other value added co-/by products. It consists of 13 chapters and is divided into three parts: cellulases; hemicellulases; and lignocellulose oxidoreductases. Written by international experts, the contributions offer clear and concise descriptions of both standard and new technologies. It is an invaluable reference resource for undergraduates, post-graduates, researchers and practitioners in the field of microbial enzymes for biofuel and biorefinery applications.
