| Abstract: | In this research, using Chinese white poplar Populus tomentosa powder made by steam explosion as substrate, reaction temperature, solution pH value, loading of cellulase and hydrolysis time on cellulase hydrolysis degree are discussed. The results are: reaction temperature, solution pH value, loading of cellulase and hydrolysis time have great effect on cellulase hydrolysis degree. The best conditions for cellulase hydrolysis are 45 ℃, pH 5.0,80 h and 25 U/g dried steam exploded poplar wood powder. |
