液体发酵灵芝菌胞外多糖的研究

Study on Extracellular Polysaccharide of LingChih Produced by Liquid Fermentation

现代临床和药理表明:灵芝具有多种生理活性和药理作用,其中灵芝多糖是灵芝的主要有效成分,通过本课题的研究,建立一套液体发酵培养灵芝菌体和生产胞外多糖的方法,并建立相关的灵芝多糖的测定方法。通过液体发酵灵芝菌,我们得到胞外多糖为3.4558g/L,高于国内文献报道的最高值3.07g/L。

Clinical and pharmacological research show LingChih has many physiological activities and pharmacological actions. The polysaccharide is the major effective component in LingChih. In this study, the liquid fermentation technics of large-scale culture LingChih for producing extracellular polysaccharide and a relevant measure of extracellular polysaccharide were established. The amount of extracellular polysaccharide reached 3.4558g/L, higher than 3.07g/L reported in the national document.
