摘要
金针菇 FV- 19菌株深层发酵醪液 .经离心、沉淀、透析处理得到发酵液多糖样品 ,并用凝胶色谱法测定其相对分子质量 .探讨了提取纯化过程对发酵液多糖相对分子质量的影响以及贮存期对其相对分子质量的影响 .
Polysaccharide samples of fermenting filtrate were isolated by means of centrifugation, sediment, dialysis from the mash of submerged culture of Flammulina velutipes (Curt.ex Fr.) Sing “FV 19”, its relative molecular mass was determined by gel permeation chromatography. The effects of the course of extraction and purification on the relative molecular mass of fermenting filtrate's polysaccharide and the effects of storage time on its relative molecular mass were explored and discussed.
