Acid-enhanced ternary DES pretreatment of wheat straw guided by Kamlet–Taft parameters: boosting lignin separation and enzymatic hydrolysis

Abstract

(25 : 50 : 1) system at 120 °C for 60 min provided the most optimal pretreatment and enzymatic hydrolysis performance for wheat straw. After pretreatment under these conditions, an 85.74% lignin extraction rate was achieved, and 72 h of enzymatic hydrolysis provided a 99.67% polysaccharide degradation rate and 74.59% reducing sugar yield. This DES system maintained good pretreatment performance even after four reuse cycles. Moreover, this pretreatment strategy demonstrated good applicability to multiple biomass types, providing a novel approach for developing efficient and environmentally friendly lignocellulose separation technologies.
