摘要:

目的:研究拟康氏木霉菌丝多糖的最佳提取工艺条件。方法:以多糖提取率为考察指标,通过单因素试验和正交试验研究拟康氏木霉多糖的最佳提取工艺。结果:影响拟康氏木霉多糖提取率的因素顺序为回流温度>提取次数>提取时间>粉碎粒度;最佳工艺条件为粉碎过120目筛,料液比1:30(g/mL),100℃沸水回流提取3次,每次2h,在此条件下,拟康氏木霉菌丝多糖得率为(11.09±0.13)%。结论:该工艺稳定可行,可作为拟康氏木霉菌丝多糖的提取条件。

Abstract:

Objective: To study the optimal extraction conditions of polysaccharides from Trichoderma pseudokoningii mycelium.
Methods: One-factor-at-a-time experiments and orthogonal array design were applied to establish the optimum extraction
conditions based on the yield of polysaccharide. Results: The influence of three factors on extraction efficiency decreased in the
following order: reflux temperature > extraction number >extraction time > particle size. The optimal extraction conditions
were obtained as follows: three extraction cycles at 100 ℃ for 2 h each with a solid/liquid ratio of 1:30 (g/mL). Under these
conditions, the yield of polysaccharides from Trichoderma pseudokoningii was (11.09 ± 0.13)%. Conclusion: The optimized
process is stable, feasible and applicable for the extraction of polysaccharides from Trichoderma pseudokoningii mycelium.
