Biological degradation of lignocellulosic materials typically occurs through a synergistic action of a complex enzyme system. Intensive research has been carried out in search of highly efficient cellulases and hemicellulases over last decade. A number of cost effective enzyme products are commercially available today.

To further advance enzymatic solution in this field, this presentation will highlight research that demonstrates a positive impact from oxidoreductases in production of sugars from biomass. A significant enhancement of biomass hydrolysis by phenol oxidases and peroxidases will be presented.  Substrate and pretreatment dependence will be illustrated in oxidoreductase enhanced biomass hydrolysis, and the potential of industrial applications will be discussed. The detoxification and stabilization of other hydrolytic enzymes by oxidoreductase are proposed based on findings in biomass hydrolysis.
