摘要:
以灵芝真菌为试材，研究了10 L发酵罐发酵培养好氧型灵芝真菌条件下，溶氧控制条件对生产灵芝酸产量的影响。结果表明：溶氧对灵芝真菌发酵生产灵芝酸的影响较大，高通气量有利于缩短发酵时间，适宜的通气量为0.4 L?L-1?min-1，此条件下，菌体和灵芝酸的最大产量分别为8.27 g/L和171.26 mg/L；相对初始发酵条件，菌体和灵芝酸最大产量分别提高13.13%和13.28%；相对于低通气量，菌体和灵芝酸达到最大产量的时间缩短12 h；表明0.4 L?L-1?min-1的通气量较适宜于10 L发酵罐发酵生产灵芝酸。
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.
