  • Patent number: 9040263
    Abstract: 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.

  • Patent number: 9012190
    Abstract: The invention relates generally to the field of industrial microbiology and alcohol production. More specifically, the invention relates to the use of thiamine, biosynthetic precursors of thiamine, nicotinic acid, nicotinamid, nicotinic acid riboside, nicotinamid riboside, or other biosynthetic precursors of nicotine adenine dinucleotide (NAD) to improve butanol production. Butanol production can be improved by providing sufficient amounts of thiamine, biosynthetic precursors of thiamine, nicotinic acid, nicotinamid, nicotinic acid riboside, nicotinamid riboside, or other biosynthetic precursors of nicotine adenine dinucleotide (NAD) in the production media.

  • Patent number: 8969055
    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.

  • Patent number: 8969065
    Abstract: A high flux in conversion of pyruvate to acetolactate was achieved in yeast through expression of acetolactate synthase in the cytosol in conjunction with reduction in pyruvate decarboxylase activity. Additional manipulations to improve flux to acetolactate are reduced pyruvate dehydrogenase activity and reduced glycerol-3-phosphate dehydrogenase activity. Production of compounds having acetolactate as an upstream intermediate benefit from the increased conversion of pruvate to acetolactate in the described strains.

  • Patent number: 8951937
    Abstract: A group of bacterial dihydroxy-acid dehydratases having a [2Fe-2S] cluster was discovered. Bacterial [2Fe-2S] DHADs were expressed as heterologous proteins in bacteria and yeast cells, providing DHAD activity for conversion of 2,3-dihydroxyisovalerate to ?-ketoisovalerate or 2,3-dihydroxymethylvalerate to ?-ketomethylvalerate. Isobutanol and other compounds may be synthesized in pathways that include bacterial [2Fe-2S] DHAD activity.

  • Patent number: 8940511
    Abstract: Yeast cells with a reduced general control response to amino acid starvation were found to have increased tolerance to butanol in the growth medium. The reduced response was engineered by genetic modification of a gene involved in the response, a GCN gene, to eliminate activity of the encoded protein. Yeast strains with an engineered butanol biosynthetic pathway and a genetic modification in a gene involved in the general control response to amino acid starvation, which have increased butanol tolerance, are useful for production of butanol.
