| Abstract | Fifteen organic solvents were examined to determine their biocompatibility for in situ extraction of fermentation products from cultures of the thermophilic anaerobe Clostridium thermohydrosulfuricum . Five solvents (hexadecane, isooctane, kerosene, oleyl alcohol, Shellsol TD) were found to be non-toxic to Clostridium thermohydrosulfuricum . Interfacial tension, phase separation and partition coefficients for ethanol of the biocompatible solvents were compared. With the exception of kerosene, these solvents showed good separation from the aqueous phase. Oleyl alcohol had the highest partition coefficient for ethanol (K sub(D) = 0.34 at 65 degree C) and appears to be suitable for extractive ethanol fermentation. |
