The results showed that during the culture of mycelium, the changes of my- celium amount and CO2 concentration accorded with the S type growth curve, and the 4^th -8^th d was the logarithmic phase with the growth amount of mycelium 0.05 g/100 ml per day. After 9 d, the mycelium growth tended to slow down, and by tile end of the mycelium cultivation, mycelium began to slightly decrease. The pH value of medium changed slightly in 0.5 during the mycelium cultivation. The three groups of parameters showed that the liquid strain fermentation time should be 8 to9d.展开更多
