| Research Abstract |
In the present study, it is discovered that microwave irradiation to cellulose in the presence of tungstosilicic acid gave glucose (direct saccharification) with highly efficiency. The effects of crystal structure as well as solvent onto direct saccharification by microwave irradiation in the presence of hetero-poly acids such as tungstosilicic acid were investigated. The mixed solvent of water and ethanol could proceed the direct saccharification with highly glucose yield of 80%. The pretreatment on tungstocilicic acid is effective to improve the glucose yield. The direct saccharification of cellulose by the microwave irradiation in the presence of tungstocilicic acid depends strongly on the amount of water and its characteristics in the crystalline of tungstocilicic acid. Thus, it was found that the extremely high glucose yield can be achieved when the suitable condition was adopted. The highest yield of direct saccharification from cellulose to glucose reached 99%.
