Hydrolysis of sugarcane bagasse was successfully achieved by using GVL/water solution.
Higher sulfuric acid concentration of 50 mM resulted in no remarkable effects
on the degradation rate of sugarcane bagasse in all experiments
, which was in agreement with the results of levoglucosan production [5].
Hydrolysis of biomass by dilute acid is typically carried out with at least 0.5–2 wt% [18], while low concentration of 5 mM (∼0.05 wt%) was needed by using the GVL/water solution, which could avoid the recovery process of mineral acid and improve the economics of biomass-derived products.
Dramatic decrease in the concentration of glucose, xylose, and arabinose were observed with the increase of biomass loading.
