摘要
以胞外多糖为指标,通过摇瓶培养的方式对白灵菇液体发酵培养基及培养条件进行了研究。结果表明,白灵菇液体发酵产胞外多糖的最佳培养基组合为:葡萄糖2%、蛋白胨0.75%、CaCl20.2%;白灵菇液体发酵产胞外多糖的最佳发酵条件为:起始pH值7.0,接种量20%,装液量120mL,培养天数6d。
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.
