In this study, a co-production of two high value-added products, glucose and xylooligosaccharides (XOS), was investigated by utilizing sugarcane bagasse (SB) within a multi-product bio-refinery framework optimized by Box-Behnken design-based response surface methodology. The developed process resulted in a maximum cellulose conversion of xylan-removed SB, 98.69+/-1.30%, and a maximum extracted SB xylan conversion into XOS (xylobiose and xylotriose) of 57.36+/-0.79% that was the highest SB xylan conversion reported in the literature, employing cellulase from Penicillium oxalicum EU2106 and recombinant endo-β-1,4-xylanase in Pichia pastoris. Consequently, a mass balance analysis showed that the maximum yields of glucose and XOS were 34.43+/-0.32g and 5.96+/-0.09g per 100g raw SB. Overall, this described process may be a preferred option for the comprehensive utilization of SB.
