Abstract:
Taking Ganoderma as material，the effects of 10 L fermentor culture under aerobic conditions Ganoderma fungus dissolved oxygen(DO) conditions on the production of ganoderic acid were studied.The results showed that the yield for ganoderic acids was significantly effected by DO and the fermentation time was shorten by 0.4 L?L-1?min-1 alveolar ventilation.The maximum yield of mycelium and ganoderic acids was 8.27 g/L and 171.26 mg/L under the conditions of 0.4 L?L-1?min-1 alveolar ventilation，the maximum yield of mycelium and ganoderic acids increased 13.13% and 13.28% respectively，the fermentation time shorten 12 h，this showed that it was effectively to increase the yield of mycelium and ganoderic acids under the conditions of 0.4 L?L-1?min-1 alveolar ventilation.
