响应面法优化姬松茸液体发酵培养基中红糖和酵母膏浓度

Response Surface Methodology for Optimization of the Concentration of Brown Sugar and Yeast Extract for Mycelial Biomass and Exopolysaccharide Yield of Agaricus blazei

运用响应面分析法优化姬松茸液体发酵培养基中红糖和酵母膏浓度。结果表明,红糖浓度为20.24g/L、酵母膏浓度为2.055g/L时,菌丝体生物量最高,达2.279g/L;红糖浓度为20.8g/L、酵母膏浓度为2.23g/L时,胞外多糖产量最高,达0.749g/L。

Response surface experiments were conducted on Agar/cus blazei to determine the optimal concentration of brown sugar and yeast extract for mycelial biomass and exopolysaccharide yield. The results showed that the mycelial biomass could reach of 2. 279g/L when the concentrations of brown sugar and yeast extract were 20.24g/L and 2. 055g/L respectively. And the exopolysaccharide yield could reach of 0. 749g/L when the concentrations of brown sugar and yeast extract were 20.8g/L and 2.23g/L respectively.
