Abstract

•Oleyl alcohols were used to partially substitute the water to investigate its effect.•Insoluble solids was found in batch hydrolysis with diverse ratio of water was replaced.•Fed-batch hydrolysis was carried out with solvent water/oleyl alcohol ratio of 3:1.•Glucose production was found to be less than pure water hydrolysis system.•Solids effect was related to the solvent water content.

Solvent water is an essential factor for high solids enzymatic hydrolysis. To investigate its effect on substrate conversion efficiency in high solids hydrolysis of sugarcane bagasse (SCB), oleyl alcohol was used to partially substitute the solvent water. The results in batch hydrolysis tests in which diverse ratio of solvent water was replaced found that the majority of the substrate was insoluble. Then high solids fed-batch hydrolysis with the reaction solution mixed with solvent water and oleyl alcohol in the ratio of 3:1 (solids concentration correspond to 24% (w/v)) was carried out at the final real solids loading of 18% (w/v). The produced sugars were found to be less than pure water system, which indicated that water played a significant role in high solids hydrolysis process, and solids effect was related to the solvent water content.
