In order to improve the yield of reducing sugar from corn stalk, ultrasonic-assisted ammonium bicarbonate pretreatment of corn stalk was proposed. Three ultrasonic factors (time (0-30 min), temperature (30-60 °C) and liquid/solid mass ratio (5-20)) were optimized by response surface experiment. The optimal conditions of ultrasonic pretreatment were obtained (liquid/solid mass ratio is 12:1, temperature is 42 °C and time is 11 min). The highest saccharification rate of corn stalk was of 82.61%, which was remarkably increased by 355% compared to the control group.
为了提高玉米秸秆中还原糖的产量，提出了超声辅助碳酸氢铵预处理玉米秸秆的方法。通过响应面实验优化了三种超声因素（时间（0-30 分钟）、温度（30-60°C）和液固比（5-20））。得到了超声预处理的最佳条件（液固比为 12:1，温度为 42°C，时间为 11 分钟）。与对照组相比，玉米秸秆的糖化率最高可达 82.61%，显著提高了 355%。
