Abstract

See full text

A bioreactor includes a fluid containment vessel and a rotating mixing element including radial inflow elements configured to direction fluid radially inwardly of the mixing element and axial out flow elements configured to redirect the radial inward flow in an axial direction. Both the vessel and the mixing element are made from plastic and the vessel comprises a flexible bag supported by a rigid housing. In one embodiment, the mixing element is pneumatically driven by the buoyancy of gas introduced into the vessel and trapped within gas entrapment cups formed on the periphery of the mixing element. As the volumetric capacity of the bioreactor increases, the ratio of the diameter of the mixing element to the width of the vessel decreases, and a gap defined between the bottom of the mixing element and the bottom of the vessel increase.
