Abstract
A cell culture bioreactor has perfusion membranes and gas transfer membranes or a gas phase in an extra-membrane space in contact with a film on the perfusion membranes. Gas transfer membranes may travel through the perfusion membranes or through the extra-membrane space. Examples with hollow fiber and flat sheet membranes are shown. One or more of the membranes optionally has a responsive surface, for example a thermo-responsive surface. In some examples, membranes are located in X-Y planes while the length of the reactor extends in a Z-direction.
