The effects of several components in the culture medium on Lithospermum erythrorhizon cell growth and secondary metabolite synthesis were studied, as well as structural dynamic model. The two-liquid-phase culture of Lithospermum erythrorhizon was carried out by choosing the proper organic solvent as the second phase. The bioactive carrier for adsorption was prepared and the condition of cell immobilization was determined. We combined the technique of two-liquid-phase culture and immobilization to carry out the culture. We chose the suitable type of reactor, studied its characteristics and results of cell culture using this reactor. The fed-batch operation was also studied on the basis of twoliquid-phase culture and immobilization used in culture in the reactor.
