Abstract:
A method for producing butanol through microbial fermentation, in which the butanol product is removed during the fermentation by extraction into a water-immiscible organic extractant in the presence of at least one electrolyte at a concentration at least sufficient to increase the butanol partition coefficient relative to that in the presence of the salt concentration of the basal fermentation medium, is provided. The electrolyte may comprise a salt which dissociates in the fermentation medium, or in the aqueous phase of a biphasic fermentation medium, to form free ions. Also provided is a method and composition for recovering butanol from a fermentation medium.
