Bioreactor

Bioreactor comprising a reaction container forming an airlift reactor for a substance to be acted upon with a medium, and a pump for conveying the medium comprising at least one of a pump for single use and single use parts for the pump, in which reaction container a hollow body is arranged which has a jacket connected at its lower end to a wall of the reaction container that tapers in the direction towards an upper end of the reaction container so that it subdivides an inner space of the reaction container into an upper chamber and a lower chamber, the upper and lower ends of the reaction container including respective upper and lower end surfaces of the hollow body which are liquid and gas permeable and enclose a cavity in which the substance to be acted upon can be arranged, a supply line for the liquid medium opening into the upper chamber and a suction device for a liquid medium and a supply device for a gaseous medium being provided in the lower chamber.
