Efficient butanol bioproduction from renewable lignocellulosic biomass by an integrated strategy of ternary deep eutectic solvent pretreatment and clostridial fermentation: toward complete utilization of reed straw.

ABSTRACT: The main route for biobutanol production is anaerobic clostridial fermentation using corn and sugarcane as substrates. The high-price of raw materials in above processes largely limits its application as an advanced biofuel. The renewable lignocellulosic biomass is an ideal feedstock to produce butanol. However, the structure of lignocellulose is complicated which needs pretreatment to facilitate enzymatic efficiency and substrate fermentability. Herein, the green ternary deep eutectic solvent (DES) composed of choline chloride, succinic acid, and glycerol was synthesized. To improve DES pretreatment performance and reduce the viscosity of reaction system, water was added as co-solvent. Results indicate that xylan removal and glucan recovery were 61.7% and 93.6% when pretreating reed straw
