摘　　要：通过正交试验研究了平菇液体培养基配方,筛选出适宜平菇菌丝体生长的最佳液体培养基配方为玉米粉2.5%,麸皮2.5%,MgSO40.15%,KH2PO40.10%,pH值为自然;适宜平菇胞外多糖产生的最佳液体培养基配方为玉米粉2.5%,麸皮2.5%,MgSO40.15%,KH2PO40.20%,pH值为自然。The influence of corn flour, wheat brain, MgSO4, KH2PO4 on Pleurotus ostreatus myceliurn dry weight and extracellular polysaccharide production were studied through orthogonal experiments. The optimal liquid medium formula for Pleurotus ostreatus mycelium was obtained as follows： corn flour 2.5%, wheat brain 2.5%, MgSO4 0.15%, KH2PO4 0.10% and pH value natural. The optimal liquid medium formula for P. ostreatus exopolysaccharide yield was as follows： corn flour 2.5%, wheat brain 2.5%, MgSO4 0.15%, KH2PO4 0.20% and pH value natural.
