• Abstract: Although high-solid enzymatic hydrolysis has emerged as an efcient strategy of sugar production from lignocellulosic materials, this process requires several steps to increase its efciency. Current strategies include treatments to remove noncellulosic macromolecules. Here, dilute alkaline extraction was controlled to remove loosely bound xylan from sugarcane bagasse, and 14.7% (w/w) was recovered by ethanol precipitation. To the supernatant, sodium sulfte (5% w/w) was added to pretreat the residual sugarcane bagasse with alkaline sulfte ethanol (ASE). The sequential process allowed the removal of 85% of lignin, producing a carbohydrate-enriched solid. Incubation of ASE-pretreated bagasse with xylanase released up to 43% of the xylan as oligomers. Subsequent enzymatic saccharifcation was performed at initial solid loadings, 5, 10, and 15%. The conversion of ASE-pretreated bagasse yielded 84.4% glucan hydrolysis or 75 g/L glucose at 15% solids after 48 h, while samples with reduced xylan contents had lower water retention, and achieved relevant glucan hydrolysis yield (73%) and glucose titer (87 g/L). Enzymatic saccharifcation at high solid loading was dependent on xylan removal, and control of excess residual xylan may play an important role in fne-tuning product formation in high-solid enzymatic hydrolysis of the glucan fraction.
