摘要
Lignocellulosic biomass is the most abundant organic raw material in the world. Due to its complexity, lignocellulosebioconversion requires the action of multiple enzymes. The complete hydrolysis of cellulose requires theaction of the cellulase system containing cellobiohydrolase, endoglucanase and -glucosidase[1]. Aspergillus spp:produce all three enzyme activities of the cellulase complex and exhibit strong hydrolytic activity towards cellulose,and Aspergillus niger has been mainly used for -glucosidase production[2]. Aspergillus niger is a kind of aerobicmicroorganisms, but there is little oxygen when it is used to silage for degrading the feed cellulose and enhancingthe feed's palatability. The aim of this study is to evaluate the influence of oxygen on the growth and cellulaseproduction of Aspergillus niger.
