With many fermentations the products limit the metabolism of the applied microorganisms. In this work the application of the process-integrated material separation procedures in-situ-extraction and in-situ-electroextraction was examined with continuous fermentations of the thermophilic, strictly anaerobic microorganism Thermoanaerobacterium thermosaccharolyticum. The simultaneous separation of the inhibitive fermentation products ethanol, lactic acid, acetic acid and butyric acid from the cultivation medium was successful.
