Abstract
An apparatus for the culturing of microorganisms in an aerobic fermentation process. The apparatus includes a vessel with a chamber or reaction zone therein. A draft tube with opposite ends is mounted in the chamber and defines a fluid flow path. A pump means is positioned adjacent one of the draft tube ends and induces flow of fluid through the draft tube and a flow path defined by the draft tube and one interior surface of the vessel. An impeller is positioned between the draft tube and the interior surface of the vessel to assist fluid flow along the flow path defined by same.
