摘要
∶建立了灵芝深层发酵过程中胞外多糖质量浓度和发酵上清液相对粘度之间关系的数学模型，从而找到了一种通过测定发酵过程中上清液相对粘度来检测胞外多糖含量的方法．模型具有较好的拟合性，平均相对误差在４．４％ 左右．
A model between extracellular polysacchride concentration and the relative viscosity of the culture supernatant during the submerged fermentation of G. lucidum was set up, and a quick method was presented by measuring the relative viscosity of culture superllatant to obtain the extracellular polysacchrides,with an average error around 4.4%.
