摘要
云芝胞内糖肽是由杂色云芝[Polystictus versicolor(L.)Fr.]经深层液体发酵培养,经提取获得的糖肽类物质。云芝发酵液适合微滤-超滤提取,超滤膜通量易恢复,微滤超滤工艺得到的云芝胞内糖肽总糖54.7%、单糖7.1%,对单糖的去除和对多糖的截留效果优于传统的水提-醇沉法。
Production of Coriolus versicolor Polysaccharopeptide by submerged fermentation is studied. Microfiltration-ultrafiltration is fitted for Coriolus versicolor fermentation broth purify. Flux of membrane filter is easy to recover. Total sugar is 54.7%, sugar is 7.1%. Microfiltration-ultrafiltration precedes water extraction-ethanol precipitation to dispose reducing sugar and intercept polysaccharide of producing polysaccharopeptide.
