Production of fructose (g) per 100 g of pretreated solid pulp after enzymatic hydrolysis with Cellic® CTec2 and isomerization with Sweetzyme® of OxiOrganosolv pretreated beechwood samples (150 °C, 60 min, O₂ 16 bar) with four different organic solvents and POMs catalysts at a loading of 5%. All experiments were run in duplicates and numbers represent the mean values. Labels indicate the production of fructose (g) per 100 g of initial untreated beechwood
