    Increased Productivity of Clostridium Acetobutylicum Fermentation of Acetone, Butanol, and Ethanol by Pervaporation through Supported Ionic Liquid Membrane

  • Original language description

    The pervaporation proved to be one of the best methods to remove solvents out of a solvent producing Clostridium acetobutylicum culture. By using an ionic liquid (IL)?polydimethylsiloxane (PDMS) ultrafiltration membrane (pore size 60 nm) we could guarantee high stability and selectivity (enrichment factor of butan-1-ol reached 11.23 at 3.75 g/l of its concentration in culture vessel) during all measurements carried out at 37°C. The supported ionic liquid membrane (SILM) was impregnated with 15 wt% of anovel ionic liquid (tetrapropylammonium tetracyano-borate) and 85 wt% of polydimethylsiloxane. Pervaporation, accomplished with the optimized SILM, led to stable and efficient removal of the solvents butan-1-ol and acetone out of a C. acetobutylicum-culture

    Zvýšení produktivity Clostridium acetobutylicum fermentace acetonu, butanolu a ethanolu pomocí pervaporace přes zakotvenou iontovou membránu

  • Czech description

    Pervaporace patří mezi nejefektivnější metody k odtranění rozpuštěných látek z rozpouštědel, které produkuje kultura Clostridium acetobutylicum. Použitím iontových rozpouštědel s polydimethylsiloxanem v ultrafiltrační membráně (velikost pórů 60 nm) můžeme garantovat vysokou stabilitu a selektivitu (stupeň obohacení butanolu dosáhl 11,23 při koncentraci v reaktoru 3.75 g/l) během všech měření při 37°C. Zakotvená iontová membrána byla impregnována 15 wt% iontové kapaliny (tetrapropylammonium tetracyano-borate) a 85 wt% polydimethylsiloxanu. Pervaporace pomocí optimalizované zakotvené iontové membrány byla stabilní a efektivní při separaci butanolu a acetonu kultury C. acetobutylicum
