A multimembrane reactor is described. Four layers (gas, cells, nutrient, and solvent) are separated by membranes. This structure prevents solvent emulsification in the fermentation broth. The system was tested for ethyl alcohol production from glucose using yeast. Tributyl phosphate (TBP) was chosen as the extractant. Experiments demonstrate for the first time a successful extractive fermentation with a practical solvent. Prevention of emulsification removes the toxic effect of TBP on yeast metabolism. (Refs. 29).
