The growth of plant cell cultures of Taxus chinensis in the airlift bioreactor and stirred tank bioreactor is studied. On the basis of the knowledge the secondary metabolism in cultured Taxus chinensis cells, the comparison research is done. The culture growth and taxol production are all analyzed. The experimental results show that culturing in the stirred tank bioreactor is more suitable for Taxus chinensis cells. The maximum dry cells weigh 18.5?g/L and the maximum taxol concentration of 20.2...
