Abstract
An apparatus for culturing a microorganism by an aerobic fermentation process. The apparatus includes a vessel having a generally centrally located draft tube mounted in a chamber defined by the vessel with the draft tube forming a flow path. The vessel and draft tube are shaped such that the flow path diverges in the direction of ferment flow therethrough. The draft tube has opposite ends with a pump positioned adjacent one end to induce circulation of ferment through the draft tube and along the flow path. A heat exchanger is suitably mounted in the vessel and is in heat transfer relation with the ferment so as to maintain a predetermined operating temperature.
