| Abstract: | Using extracellular polysaccharide as index in this paper, the appropriate liquid fermentation medium and culture conditions of Pleurotus ferulae were studied by shaking culture. The results showed that the optimal composition of the liquid fermentation medium were as follows： glucose 2%, peptone 0.75%, CaCl2 0.2%, which is suitable for producing extracellular polysaccharide. The optimal fermentation conditions were as follows： initial pH 7.0, inoculation amount 20%, liquid volume in flask 120 mL, culture time 6 d. |
