Outline of Final Research Achievements

In order to produce glucose from cellulosic biomass directly, pretreatment using steam explosion or microwave irradiation treatment were carried out. In case of steam explosion (steam pressure 55 atm, steaming time 5 min), 18.8 g of direct hydrolyzed glucose and 20.6 g of enzymatic hydrolyzed glucose from steam exploded residue (solid phase), i.e. total 39.4 g of glucose, were obtained per 100 g of dry towel. In case of microwave irradiation treatment (irradiation temperature 200℃, irradiation time 2 min) using 0.5 wt% of dilute sulfuric acid as reaction solvent, 37.7 g of direct hydrolyzed glucose and 41.5 g of enzymatic hydrolyzed glucose from microwave irradiated residue (solid phase), i.e. total 79.2 g of glucose, were obtained per 100 g of dry towel.
