Abstract
The invention relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed by extraction into a water immiscible organic extractant composition during the fermentation. The invention also relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed during the fermentation by extraction into a water-immiscible extractant composition comprising a first solvent having a butanol partition coefficient of at least 3, and a second solvent having a butanol partition coefficient, wherein the butanol partition coefficient of the first solvent is higher than the butanol partition coefficient of the second solvent. Optionally, the first solvent has a higher concentration of hydrogen bonding sites than the second solvent. The invention further relates to a composition including butanol in the water immiscible organic extractant composition described above.
