该文报告了利用气升式生物反应器进行香菇的液体深层培养的条件，培养液ｐＨ值在４５０～５２０和通气量为１∶０５０～０６０ｖｖｍ的条件下菌丝生物量达到最大；并提出了稀土对菌丝生长有促进作用，其使用浓度为２００×１０－６左右。 This paper reports the condition of deep liquid culture of Mushroom by gas-lift bioreactor. Under the conditions of pH value between 450 ~ 520 and aeration rate of 1:050 ~ 060vvm, The maximum biomass was obtained. It was also suggested that rare earth could promote mycelial growth at a concentration of 200 × 10-6.
