Coproduction of xylo-oligosaccharides and glucose from sugarcane bagasse in subcritical CO2-assisted seawater system

Abstract Abundant seawater resources can replace the shortage of freshwater resources. The co-production xylo-oligosaccharides and glucose from sugarcane bagasse by subcritical CO 2 -assisted pretreatment was studied in this paper. We investigated effects conditions temperature, pressure reaction time on yield systems. maximum xylo-oligosaccharide 68.23% obtained at 165 °C/2 MPa/5 min. After further enzymatic hydrolysis solid residue, highest 94.45% obtained. In system, there is a synergistic effect mixed ions to depolymerize xylan into with lower degree polymerization. At same time, addition increased pore size porosity bagasse, improved efficiency glucose. Therefore, study provides more environmentally friendly sustainable process for improves utilization Graphical
