| 英文摘要 | Simultaneous valorization of both carbohydrate and lignin fractions in lignocellulose remains a great challenge. Herein, a novel lignin -first strategy using triethylene glycol (TEG) under alkaline conditions for effective biomass fractionation producing highly digestible carbohydrates and reactive lignin was developed. Delignification was over 80% and fermentable sugar yields were close to 90% after pretreatment at 90 celcius. The biocompatibility of TEG allowed direct enzymatic hydrolysis of the solid residue without washing, thus minimizing wastewater generation. Moreover, the obtained lignin (TEGL) had an uncondensed structure with well-preserved beta-O-4 linkage, leading to near -equal aromatic monomer yields compared to cellulolytic enzyme lignin after catalyticfree pyrolysis, demonstrating high valorization potential. Overall, the proposed TEG solvent system is promising for a green and sustainable biorefinery process to achieve the complete utilization of lignocellulose. |
