The characteristics of continous ethanol fermentation system wity membrane separator of pervaporation were investigated. The membrane used is of hydrophobic microporous hollow fibers of polypropylene. An ethanol-water mixture of high ethanol concentration was recovered continously and directly from the fermentation broth. Intermittent backflushing by compressed nitrogen gas prevented degradation of the permeation rate. The selectivity of the membrane for ethanol was a little bit smaller than that of distillation at normal pressure. The permeation rate of ethanol was almost linearly proportional to the ethanol concentration of feed broth. The carbon dioxide gas generated by fermentation promoted the permeation rate. The ethanol concentration of permeation was estimated by the fermentation dynamic equations.
