Abstract
A vessel is provided for cultivating microorganisms. Said vessel contains a body of liquid, and a hollow rotary impeller is mounted in the vessel and has in the region of its axis of rotation a liquid inlet formed with a venturi-shaped constriction. A plurality of first gas outlets communicate with the liquid inlet in the region of the constriction so that the suction resulting from the liquid flow will pull the gas through these first outlets. A plurality of second gas outlets are located on the periphery of the impeller remote from the first outlet.
