Abstract A process for fermenting cell cultures and a fermenter. In a known fermenter, oxygen is supplied to a suspension consisting of liquid and cell cultures settled on microcarriers, an aerator being disposed at the centre of the fermenter. The aerator comprises a screen cage having baffles having oppositely directed conical passages. Although the oxygen dissolves satisfactorily in the liquid, the suspension can uptake only relatively little oxygen. The oxygen partial pressure in the suspension can be increased if the aerators are disposed eccentrically of the agitation axis in the relatively high flow velocity zones of the suspension. The process and apparatus are of use for fermenting cell cultures.
