摘　　要：对用来发酵生产木糖醇的竹笋壳半纤维素水解液的制备进行了研究。在水解单因素试验基础上确定因素的合适水平,通过正交试验优化确定了水解条件:硫酸质量浓度0.01 g/m L、温度120℃、时间1 h、液料比(m L/g)8∶1。在该条件下水解木糖得率为69.31%,使半纤维素利用率得以提高。The preparation of bamboo shell hemicellulosic hydrolysate used for production of xylitol by fermentation was studied. On the basis of single factor experiment, the optimal hydrolysis conditions were established by orthogonal experimental design with sulfuric acid concentration of 1%, reaction time of 1 h, hydrolysis temperature of 120℃, liquid to solid ratio （mg/L） of 8：1. Under above conditions, the yield of xylose was 69.31%, which could improve the utilization rate of hemicellulose.
