Abstract: A bioreactor comprising a reactor chamber defined by reactor walls and a reactor opening, optionally with means penetrating the reactor opening in order to supply gases and/or liquids, for taking samples, for supplying microorganisms or cells, for the introduction of measuring probes, for the addition of additives or sterilizing agents and/or for emptying the bioreactor, with means for sealing the reactor opening, wherein at least one inflatable eddy current breaker is installed in the reactor chamber.

Abstract: A bio-reactor for cultivating cells, comprising a culture vessel, at least one gas supply and/or liquid feed in addition to supply devices for gases and/or liquids enabling gases or liquids to be fed to the culture vessel. A mixture device, especially a Venturi nozzle is arranged between the supply device and gas supply or liquid feed in order to mix gas and/or liquid from the gas supply or liquid feed.
