Tóm tắt

For the extraction of sugars and their subsequent conversion into ethanol, removing lignin from sugarcane bagasse is a major challenge attributed to its recalcitrant nature. This study compares the efficacy of green deep eutectic solvents with conventional acid/alkali pre-treatments for the delignification of sugarcane bagasse. Among different deep eutectic solvent pre-treatments, the maximum removal of lignin i.e. 77.37% was reported when bagasse was treated with choline chloride: formic acid (1:2) for 6 h. The comparison between deep eutectic solvents and conventional acid/alkali pretreatments revealed that acid (H
