| Abstract: | The result of pretreatment on corn straw by ligninolytic enzymes produced by white-rot fungi is that hydrolysis saccharification of corn straw is inhibited by ligninolytic enzymes.The lower rate of reducing sugar and glucose concentration are 40.3% and 2.7% after pretreatment by coarse peroxidase fermentation broth;3.8% and 2.9% after pretreatment by coarse laccase fermentation broth and the lower rate of reducing sugar is 27% after pretreatment by mixed enzyme fermentation broth.This shows that the influen... |
