ABSTRACT:
Cell culture apparatus comprises a fluidized bed culture tank body in which cell attached porous material is fluidized by air flow, and a pre-culture tank for supplying medium to the fluidized bed culture tank body according to the amount of the liquid medium which is taken out of the fluidized bed culture tank body. By the use of a drain valve which can be controlled to remove liquid medium and porous material or just liquid medium, the cell culture apparatus can continuously produce metabolite.
