A membrane bioreactor for alcohol fermentation is presented in this paper. Membrane distillation process was used for the removal of ethanol. The ethanol fluxes through the polypropylene membrane were approximately 2-3.5 kg EtOH/m2d. The yield of ethanol equals 0.45-0.51 g EtOH/g sugar was obtained.
