逍遥丸药渣的纤维素酶解工艺优化

Optimization of Enzymatic Hydrolysis Conditions of Xiaoyao-pill Herb Residues by Cellulase

目的:探讨逍遥丸药渣的纤维素酶解工艺参数。方法:在单因素试验基础上,选取纤维素酶添加量、酶解时间、料液比为影响因素,酶解得率为响应值,运用Box-Behnken设计对逍遥丸药渣的纤维素酶解工艺参数进行优化,建立数学回归模型。结果:逍遥丸药渣的纤维素酶解优化工艺参数为:纤维素酶添加量6%、酶解时间5.6 h、料液比1∶12(g/m L),在该条件下的酶解得率高达43.89%。结论:该方法能够获得较高的发酵糖,为中药渣的资源化利用奠定基础。

Objective: To explore the enzymatic hydrolysis conditions of Xiaoyao-pill herb residues by cellulose. Methods: Based on the single factor test,an Box-Benhnken design was used to optimize the parameters,three factors,including cellulase dosage,enzymolysis time,and solid-liquid ratio were regarded as investigation factors,the yield of enzymatic hydrolysis as index,Xiaoyao-pill herb residues enzymatic hydrolysis catalyzed by cellulase,and a mathematical regression model was established. Results: The optimal parameters were obtained as follows,cellulase dosage was 6%,enzymolysis time was 5. 6 h and solid-liquid ratio was 1 ∶ 12( g / m L). Under this condition,the yield of enzymatic hydrolysis was 43. 89%. Conclusion: The results may provide new reference for further exploring Chinese herbal medicine efficiently.
