| 英文摘要 | Acid hydrotrope pretreatment has attracted widespread attention due to its efficient separation of lignocellulose. However, current acid hydrotrope pretreatment needs a large quantity of hydrotrope, and its recovery requires high energy consumption. In this study, wheat straw was pretreated using low-concentration p-toluenesulfonic acid (p-TsOH) to maximize the production of fermentable sugars. p-TsOH from the hydrolysate was recovered by hyper-cross-linked resin. The results showed that under the optimal pretreatment conditions (1 % p-TsOH, reaction temperature at140 degrees C and reaction time at 1.5 h), the xylose yield was 85.66 %, and the cellulose conversion from enzymatic hydrolysis of pretreated wheat straw was 94.65 %. Furthermore, the recovery rate of pTsOH was 98.23 %. It is noteworthy that the hydrolysate can be used for microbial fermentation without detoxification, and the fermentation efficiency is comparable to synthetic medium. All in all, this study provides a reliable, low-cost, and recyclable pretreatment technology for the efficient utilization of lignocellulose. |
