Effects of different concentrations of H2SO4 during MAG50 pretreatment on sugar recovery and furfural concentrations in GXRS (A), pulp yield (B), and sugar yield after enzymatic saccharification of pulp with 10 FPU cellulase (C). The pretreatment reaction of SCT 1/15 (w/v) was performed at 140 °C and 150 °C for 30 min with 50% aq. glycerol, 360 µM alum, and 0.25–1.0% H2SO4. Data represent the average value of three experiments. Error bars are the standard deviation (SD) from the mean value
