In this study, the pervaporation membrane was used not only for the detoxification of sweet sorghum bagasse (SSB) hydrolysate, but also for butanol separation from its fermentation broth. As a result of detoxification, about 94.5% furfural was reduced by the pervaporation method, and 138.25 g/L furfural was obtained in the permeate side. 87.5% phenolic compounds were degradated by further laccase detoxification. As for fermentation part, 12.3 ± 0.1 g/L butanol, 6.1 ± 0.05 g/L acetone and 2.5 ± 0.07 g/L ethanol were obtained. And after 2 h of pervaporation separation, 201.9 g/L butanol, 76.2 g/L acetone and traces of ethanol were obtained in the permeate. The hybrid pervaporation process shows promising for the industrial production of biofuel butanol and biochemical furfural.
► Sweet sorghum bagasse was hydrolysis by acetic acid. ► Pervaporation membrane was used for detoxification of sweet sorghum bagasse hydrolysate. ► Pervaporation integrate with laccase was an efficient method in detoxification of lignocellulose hydrolysate. ► Biochemical furfural and biobutanol were yield by hybrid pervaporation process.
