Summary
Carbon dioxide can be used as the fluid continuous phase for the fermentation of 10 to 40 % aqueous solutions of glucose into ethanol with Saccharomyces cerevisiae using a closed circuit consisting of a fluidized bed of small solid yeast particles, a cooled condenser for the sampling of water and ethanol and a blower. At 18°C, a fermentation of 12 μmoles glucose per min per g dry weight of yeast was achieved.
