     ionic liquids (ils) are promising solvents for the pretreatment of lignocellulose as they are thermally stable, environmentally friendly, recyclable, and have low volatility. this study evaluated the effect of 1-ethyl-3-methylimidazolium acetate ([emim][oac]) for the pretreatment of energy cane bagasse in terms of biomass composition, structural changes and enzymatic digestibility. energy cane bagasse was pretreated with [emim][oac] (5% (w/w)) at 120 °c for 30 min followed by hydrolysis with commercially available enzymes, spezyme cp and novozyme 188. il-treated energy cane bagasse resulted in significant lignin removal (32.0%) with slight glucan and xylan losses (8.8% and 14.0%, respectively), and exhibited a much higher enzymatic digestibility (87.0% and 64.3%) than untreated (5.5% and 2.8%) or water-treated (4.0% and 2.1%) energy cane bagasse in terms of both cellulose and hemicellulose digestibilities, respectively. the enhanced digestibilities of il-treated biomass can be attributed to delignification and reduction of cellulose crystallinity as confirmed by ftir and xrd analyses.
