Animal cell line culture is difficult in the existing conventional bioreact
ors. A substantial amount of animal cells are destroyed by the impinging fa
n blades or entrapment inside the bubbles. An endeavor has been made to des
ign and develop a new type of bioreactor suitable for animal cell culture.
The bioreactor is named a 'see-saw' bioreactor from its underlying principl
e of operation. In this paper, the oxygen transfer characteristics of the '
see-saw' bioreactor are modeled and tried to be verified.
