AB Biorefinery with deep eutectic solvent (DES) is an emerging processing technology to overcome the shortcomingsof conventional biomass pretreatments. This work evaluates the biorefinery of sugarcane bagasse (SCB) with DESformulated with choline chloride as hydrogen bond acceptor and three hydrogen bond donors: lactic acid, citricacid, and acetic acid. Acetic acid showed unique ionic properties responsible for the selective removal of ligninand the deconstruction of cellulose to improve the digestibility of up to 97.61 % of glucan and 63.95 % of xylanduring enzymatic hydrolysis. In addition, the structural characteristics of the polysaccharide-rich material (PRM)were analyzed by X-rays, ATR-FTIR, SEM, and enzymatic hydrolysis, and compared with the original materialsample, for a comprehensive understanding of biomass deconstruction using different hydrogen bond donors(HBD) as DES pretreatment.
