title: Effect of steam explosion and microbial fermentation on cellulose and lignin degradation of corn stover.
abstract: In order to increase nutrient values of corn stover, effects of steam explosion (2.5 MPa, 200 s) and Aspergillus oryzae (A. oryzae) fermentation on cellulose and lignin degradation were studied. The results showed the contents of cellulose, hemicellulose and lignin in the exploded corn stover were 8.47%, 50.45% and 36.65% lower than that in the untreated one, respectively (P<0.05). The contents of cellulose and hemicellulose in the exploded and fermented corn stover (EFCS) were decreased by 24.36% and 69.90%, compared with the untreated one (P<0.05); decreased by 17.35% and 38.59%, compared with the exploded one (P<0.05). The scanning electron microscope observations demonstrated that the combined steam explosion and fermentation destructed corn stover. The activities of enzymes in EFCS were increased. The metabolic experiment showed that about 8% EFCS could be used to replace corn meal in broiler diets, which made EFCS become animal feedstuff possible.
