The saccharification of cellulose using subcritical water and cellulase enzyme was investigated. At first, cellulose was hydrolyzed in subcritical water at 200-300℃ and 10MPa for 10min of reaction time. As a result, the target product, glucose, and the unwanted product, 5-hydroxy-2-methylfurfural (5-HMF), were produced and a part of cellulose was carbonized above 260℃. On the other hand, in a short reaction time of 1-5min at 240℃ and 5MPa, only glucose produced, and 5-HMF and coke were not detected. Subcritical water treatment was followed by enzymatic hydrolysis. The glucose yield increased by the pretreatment of subcritical water hydrolysis. A minute pretreatment using subcritical water at 240℃ and 5MPa went up the glucose yield by 25%. From these results, subcritical water treatment was effective for the glucose production from cellulose.
