Abstract:
Taking Auricularia auricular ‘Shennong A8’ collected from Qinba Mountains as materials，on the base of single facter experiments，the liquid culture medium of Auricularia auricular strain was optimized by Box-Behnken design.The results showed that the best carbon source was glucose and the best nitrogen source was beef powder，and the concentration of glucose，beef powder and KH2PO4 were the influential parameters on the mycelial biomass.And the best liquid culture medium was achieved and listed as follows：2.16% glucose，0.48% beef powder，15% potato，0.33% KH2PO4，0.1% MgSO4?7H2O.Under the optimal conditions，the mycelial biomass of Auricularia auricular was 11.37 g/L，compared with the theoretical value 11.11 g/L，the relative error was 2.34%.So the response surface method is effective and feasible for the optimization of liquid culture mediums of Auricularia auricular strain.
