A fermentation apparatus is provided wherein a vessel has mounted therein a draft tube with an impeller adjacent one end thereof to induce circulation of ferment medium through the draft tube and a flow path defined by portions of the draft tube and the vessel. A plurality of conduits have major portions thereof positioned exteriorly of the vessel with the ends thereof opening into portions of the vessel to provide a flow loop for medium from the vessel. Heat exchange means, pump means and oxygen introduction means are provided in each of the conduits to facilitate the fermentation process. In operation, medium taken from one portion of the vessel is returned to another portion of the vessel in a cooled and oxygen-enriched state.
