Lignocellulose is usually pretreated as a raw material, and then it undergoes hydrolysis, fermentation, and other processes to produce biofuels, which is conducive to improving the utilization of agricultural and forestry wastes. However, most pretreatments, such as acid–base, CO₂ explosion, and microbial degradation, could enhance the yield of enzymatically hydrolyzed (EH) sugars, but the conditions are relatively harsh, environmentally unfriendly, and economically unfeasible. Ionic liquids, in view of their excellent physical and chemical properties and strong solubility, have been proven to be an effective green solvent for pretreating lignocellulose. The aim of this study was to exploit tetrabutylammonium hydroxide (TBAOH) and tetramethylammonium hydroxide (TMAOH) aqueous solutions to pretreat corn cob under relatively mild conditions.

氢氧化四丁基铵（TBAOH）和氢氧化四甲基铵（TMAOH）增强木质纤维素的酶水解作用

木质纤维素通常作为原料进行预处理，然后进行水解，发酵和其他过程来生产生物燃料，这有利于提高农业和林业废物的利用率。但是，大多数预处理，例如酸碱，CO ₂爆炸和微生物降解可提高酶水解（EH）糖的产量，但条件相对苛刻，对环境不利且在经济上不可行。鉴于离子液体的优异的物理和化学性质以及较强的溶解性，已被证明是预处理木质纤维素的有效绿色溶剂。这项研究的目的是在相对温和的条件下利用氢氧化四丁基铵（TBAOH）和氢氧化四甲基铵（TMAOH）水溶液对玉米芯进行预处理。
