| Abstract: | Cordyceps tenuipes is an important and rare Cordyceps species. Its anamorph isIsaria tenuipes. Biological characteristics and optimized domestication of C.tenuipeswere studied. It was found that substrates consisted of wheat and rice might be of great significance to improve the yield of the coremia in commercial cultivation. The optimal substrates for mycelial growth of C.tenuipesin both solid culture and liquid culture were basically the same. The optimal media for mycelial growth consisted of sucrose 30g/L, yeast powder 15g/L, KH2PO4 2g/L and MgSO4·7H2O 2g/L. Under the temperature of 25°C and pH value of 7, the biological efficiencies of the coremia cultivated with wheat medium ranged from (45.750±6.062)% to (67.820±6.018)%, showing superior than those cultivated with rice medium ranged from (23.410±5.242)% to (36.880±8.812)%. The highest biological efficiency of the coremia cultivated in wheat medium with superaddition of silkworm chrysalis powder was 67.820%, being higher than that previously recorded. These findings may provide useful reference for the commercial cultivation in future. |
