摘要：Herein, novel gamma-valerolactone (GVL)/saline water biphasic system was first introduced to depolymerize the recalcitrant structure of moso bamboo for further comprehensive utilization. Notably, as the main constituent of saline water, NaCl was initially investigated as control group to discuss the synergistic effect between NaCl and GVL. More than 90.7% of cellulose could be preserved under the optimum condition, followed by 97.9% of hemicellulose and 93.4% of lignin being separated, respectively. Meanwhile, the solvation effect of solvent molecules on lignin units was also verified by molecular dynamics simulation. Interestingly, more than 95.2% of hemicellulose and 86.8% of lignin were separated with 87.6% of cellulose preserved when saline water was directly introduced. This study exhibited an efficient process for simultaneous separation of sugars and lignin in lignocellulose, which provides an eco-friendly and environmentally benign method for biorefinery.
