Optimization of Cellulolytic Enzyme Systems for Lignocellulose Hydrolysis

  • Chapter
  • First Online:
Fungal Cellulolytic Enzymes

Abstract

The use of cellulase to degrade cellulose during the production of fuel ethanol is of crucial importance for solving energy and environmental problems and has attracted the attention of scientists from all over the world since the 1960s. However, the composition of the cellulase system is complex and key problems remain, such as low degradation efficiency, high production costs, and a still unclear catalytic mechanism, which seriously hinder the use of cellulase. In this chapter, the source and composition of cellulase enzymes and the mechanism of cellulose degradation are discussed. The concept of the minimal or “core” cellulase is introduced, and the engineering of the cellulase system is discussed.
