Abstract

|
Lignocellulosic biomass such as agricultural and forestry waste is the most abundant renewable organic carbon source on earth and can be used to produce source of clean energy such as ethanol. One of the disadvantages of the preparation of ethanol using lignocellulose as raw material is the high cost of production of cellulase. Fungi are capable of effectively degrading lignocellulose and secreting a large amount of cellulase, and have the advantages of ease of preparation, high yield, and full enzyme systems. Therefore, this paper reviews sources of lignocellulose and the biodegradation properties which limit the production of cellulase, proposes micro-organisms capable of degrading lignocellulose and explains the types of cellulase, and the mechanism of action, methods of fermentation optimization, and control are analyzed, and ways to increase the yield of cellulase are described. Finally, research on the effects of inducers on the production of cellulase by fungi is reviewed. The aims of this review are to provide a reference for the efficient production and industrial application of cellulase.
