In situ product recovery by adsorption in the butanol/isopropanol batch fermentation

SummaryIn the butanol/isopropanol batch fermentation adsorption of alcohols can increase the substrate conversion. The fouling of adsorbants by cells and medium components is severe, but this has no measured effect on the adsorption capacity of butanol in at least three successive fermentations. With the addition of some adsorbants it was found that the fermentation was drawn towards the production of butyric and acetic acid.
