HYDROLYSIS OF PAPER SLUDGE CELLULOSE FOR BIOGAS PRODUCTION

摘要

The present invention proposes a cellulose hydrolysis method including contacting a fermentation medium comprising paper sludge as carbon source with cellulase obtained on site from cellulase bacteria, until the mean glucose monomer number of cellulose molecules in the fermentation medium is decreased to a range between 5 and 500. The present invention further proposes a high-yield and low-cost method of biogas recovery from paper sludge.
