Résumé

Current utilization of reed scraps (RS) from reed pulping mills is just burning and burying, remaining the unused RS a major industry waste. The aim of this study was to valorize RS by utilizing it as feedstock for xylo-oligosaccharide (XOS) production. The RS was subjected to dilute acid, alkaline, and liquid hot water (LHW) pretreatments to get the pretreated RS, which was then subjected to xylanase and subsequently cellulase enzymatic to produce XOS and glucose as well. The highest yield of XOS and glucose were 0.144 g and 0.304 g / g of RS, respectively, which were obtained from the LHW pretreatment under the optimized conditions of 170 °C, 1:8 solid loadings and 30 min duration. Overall, by upgrading RS waste into XOS and glucose as value-added products of reed pulp production, we thereby paved a new way in this research to valorize the waste from reed pulping mills.
