Abstract

Graphical abstract: Highlights: FRs hydrolysate could be used for butanol fermentation. Mixed sterilization of hydrolysate/CSL/AC/resin was adopted for detoxification. Proteins in CSL could absorb toxics compounds during sterilization. Abstract: The toxicity of furfural residues (FRs) hydrolysate is a major obstacle in its application. This work focused on the detoxification of FRs hydrolysate and its application in butanol fermentation. Combination of activated carbon and resin 717 was appropriate for the detoxification of hydrolysate. Mixed sterilization of FRs hydrolysate and corn steep liquor (CSL) was better than the separate ones, since proteins in CSL could adsorb and remove toxic components during sterilization. The results further confirmed that simultaneous sterilization of activated carbon + resin and fermentation medium was more efficient for detoxification and butanol production, in which 76.4% of phenolic compounds and 99.3% of Maillard reaction products were removed, 8.48 g/L butanol and 12.61 g/L total solvent were obtained. This study provides feasible and economic approaches for the detoxification of FRs hydrolysate and its application in butanol production.
