Patent number: 9469584Abstract: 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.Type: GrantFiled: March 14, 2014Date of Patent: October 18, 2016Assignee: Butamax Advanced Biofuels LLCInventors: Douglas Robert Anton, John W.

Patent number: 9206448Abstract: In an alcohol fermentation process, oil derived from biomass is chemically converted into an extractant available for in situ removal of a product alcohol such as butanol from a fermentation broth. The glycerides in the oil can be chemically converted into a reaction product, such as fatty acids, fatty alcohols, fatty amides, fatty acid methyl esters, fatty acid glycol esters, and hydroxylated triglycerides, and mixtures thereof, which forms a fermentation product extractant having a partition coefficient for a product alcohol greater than a partition coefficient of the oil of the biomass for the product alcohol. Oil derived from a feedstock of an alcohol fermentation process can be chemically converting into the fermentation product extractant.Type: GrantFiled: June 17, 2011Date of Patent: December 8, 2015Assignee: Butamax Advanced Biofuels LLCInventors: Douglas Robert Anton, Jelena Cirakovic, Bruce A. Diner, Michael Charles Grady, Francis J. Woerner

Patent number: 9175315Abstract: An alcohol fermentation process and composition that includes production of alcohol esters by esterification of product alcohol in a fermentation medium with a carboxylic acid (e.g., fatty acid) and a catalyst (e.g., lipase) capable of esterifying the product alcohol, such as butanol, with the carboxylic acid to form the alcohol esters. The alcohol esters can be extracted from the fermentation medium, and the product alcohol recovered from the alcohol esters. The carboxylic acid can also serve as an extractant for removal of the alcohol esters from the fermentation medium.Type: GrantFiled: June 17, 2011Date of Patent: November 3, 2015Assignee: BUTAMAX ADVANCED BIOFUELS LLCInventors: Douglas Robert Anton, Stephane Francois Bazzana, Keith H Burlew, Jelena Cirakovic, Robert Dicosimo, Bruce A Diner, Michael Charles Grady, Brian Michael Roesch, Francis J Woerner
