自行设计研制了７Ｌ，９Ｌ及２５Ｌ内循环气升式生物反应器，并应用于甘草细胞的放大培养研究。在接种量为８％（Ｗ／Ｖ）通气率为０．２—０．２５ｖｖｍ的条件下，甘草细胞在反应器中生长迅速。其中在９Ｌ反应器中生长最好，最高生物量达１６．２５ｇ／Ｌ，生长速率达０．９ｇ／Ｌ．ｄ，均高于摇瓶培养。培养过程中ｐＨ值、溶氧状况通过电极自动显示记录，说明设计的气升式生物反应器适合于甘草细胞的大规模培养。 The 7L, 9L and 25L inner loop airlift bioreactors have been designed and developed by themselves, and applied to the magnification and culture of licorice cells. Licorice cells grew rapidly in the reactor with an inoculum of 8% (W / V) aeration rate of 0.2-0.25 vvm. The best growth in 9L reactor, the highest biomass of 16.25g / L, the growth rate of 0.9g / L. d, both higher than shake flask culture. During the cultivation process, the pH and dissolved oxygen status were automatically displayed and recorded by the electrode, indicating that the designed airlift bioreactor is suitable for large-scale cultivation of liquorice cells.
