摘要
研究了葡萄糖浓度和pH值调控对糖质溶液中发酵生产灰树花胞外多糖的影响。葡萄糖浓度为5%时胞外多糖产量最高 ;发酵液pH控制为 3 5～ 4 0时有利于胞外多糖的合成 ;并尝试了重复使用菌丝体在糖质溶液中发酵生产灰树花胞外多糖的新方法。
Effects of glucose concentration and pH\|control upon production of exopolysaccharides of Grifola frondosa was studied.The results showed that glucose at concentration of 5% was favorable to exopolysaccharides production,and the pellets benefited from the controlled start pH as well as the controlled final pH of 3 5～4 0 to produce exopolysaccharides.Attempt on the exopolysaccharides production with recycled pellets in the saccharoid solution was also made in this work.
