Coproduction of xylo-oligosaccharides,fermentable sugars,and lignosulfonates from sweet gum
In this work,a novel process has been developed to coproduce valuable sugars,xylo-oligosaccharides,and lignosulfonates from hardwood.The modified process includes a mild autohydrolysis,which enables for the recovery of the xylo-oligosaccharides in auto-hydrolysate.Following enzymatic hydrolysis,the residue is sulfomethylated to produce lignosulfonates.Recycling the sulfomethylation residues increased both the glucan recovery and lignosulfonate production.The glucose recovery was increased from 81.7%to 87.9%.Steady state simulation using 100 g of hardwood biomass produced 46.7 g sugars,5.9 g xylo-oligosaccharides,and 25.7 g lignosulfonates,which were significantly higher than that produced from no-recycling process with 39.1 g sugars,5.9 g xylo-oligosaccharides,and 15.0 g lignosulfonates.The results indicate that this novel biorefinery process can improve the production of fermentable sugars and lignosulfonate from hardwood as compared to a conventional biorefinery process.
