Cellulose is an abundantly available and renewable carbohydrate polymer in nature. It is the most promising feedstock for production of energy, food, and chemicals. In order to utilize as feedstock for production processes, cellulose degradation to glucose is essential, but cellulose is hardly soluble in conventional solvent. Solvent systems used to dissolve cellulose suffer some drawbacks such as volatility or generation of poisonous gas. Furthermore, to fully dissolve cellulose, multi-step pretreatments are needed. Ionic liquids (ILs) are attracting increasing attention as a new class of solvent.
Their solvent physico-chemical properties could be tuned by changing their component ions. Although these promising properties suggest that appropriate ILs would be nonvolatile polar solvent for cellulose, the significant decrease in cellulase activity in the present of cellulose-dissolving ILs retard its applications. In this study, cellulase from difference sources were screened for the hydrolysis of cellulose dissolved in ILs. Moreover, several ILs were screened for the compatible cellulose solubility and cellulase activity.
