FIELD: chemistry.
SUBSTANCE: extrusion bioreactor with a membrane device for supplying and sterilising a gas feed has cylindrical housing with a heat exchange jacket, a cover, a bottom, a gas distribution device and gas-permeable polymer tubular membranes placed along the axis of the housing. Inside the housing along its centre axis there is a gas carrying pipe which is connected to the gas distribution device, on which are mounted equally spaced perforated discs, through some of the holes of which pass the gas-permeable polymer tubular membranes, attached between the cover and the gas distribution device.
EFFECT: high working pressure of the gas in the gas permeable polymer tubular membranes and high oxygen mass transfer inside said membranes.
