Abstract
The influence of corn flour,wheat brain,MgSO4,KH2PO4 on Pleurotus ostreatus mycelium 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.
