| Abstract: | The effect of cellulase concentration,temperature,pH,reaction time and solid-liquid ratio on hydrolysis rate was studied and the hydrolysis rate of batch feed enzyme and batch enzymatic hydrolysis was compared.The optimum condition was 30 U/g cellulase,1∶10 of liquid-solid ratio,55 ℃,pH 4.8 for 48 h.Both batch feed enzyme and batch enzymatic hydrolysis could improve hydrolytic rate.Hydrolytic rate could reached to 33.42% and 27.50%,respectively after third feeding cellulase enzymatic and batch enzymatic hydrolysis three times. |
| Keywords: | corn straw cellulase enzymolysis rate |
