| 摘 要： | 通过单因素实验研究纤维素酶辅助提取泡叶藻聚糖时液料比、酶添加量、酶解温度、酶解时间等关键因素对泡叶藻聚糖提取率的影响，并进一步采用Box-Behnken实验设计和响应面分析法优化其工艺参数. 结果表明，纤维素酶辅助提取泡叶藻聚糖的优化工艺条件为液料比30 mL/g、酶浓度200 IU/mL、酶解时间2.0 h、酶解温度50℃，该条件下多糖提取率为14.65%?0.73%，与模型预测值14.75%非常接近，采用响应面法对泡叶藻聚糖提取条件进行优化合理可行.

| Abstract: | In order to obtain the optimum parameters for the cellulase assisted extraction of ascophyllan from brown seaweed Ascophyllum nodosum, the effects of several factors including water to biomass ratio, cellulase concentration, enzymolysis temperature, and enzymolysis time on the extraction yield of ascophyllan were investigated by using a single factor experiment and further optimized by using Box-Behnken experiment and response surface methodology (RSM). The results revealed that the optimal parameters for ascophyllan extraction were ratio of water to biomass 30 mL/g, cellulase concentration 200 IU/mL, enzymolysis temperature 50℃, enzymolysis time 2.0 h. Under these conditions, the actual extraction yield of ascophyllan was 14.65%±0.73%, in keeping approach with the predicted value by RSM (14.75%). Therefore, it is feasible that utilized RSM to optimize the conditions of extracting ascophyllan with the assist of cellulase. |
