| Outline of Final Research Achievements |
Ionic liquid (IL) is a salt composed of an organic cation and a variety of organic and inorganic anions, and some of them can dissolve cellulose under mild condition without any other compound. After dissolution of cellulose in IL, cellulose is easily regenerated by the addition of an anti-solvent such as water. For the effective hydrolysis of cellulose treated with IL, it is necessary to prepare the cellulase mixture containing an adequate ration of cellulase component according to crystal allomorph and the crystallinity of regenerated cellulose. Here, the reactivity of each monocomponent cellulase for the regenerated cellulose is investigated. As a result, ILs that provide cellulose II type regenerated cellulose were better suited for enzymatic degradation. Furthermore, endoglucanase was more effective for the degradation of regenerated cellulose rather than exo-type cellulase.
