  • Publication number: 20180010155
    Abstract: Microorganisms and methods of producing n-butyraldehyde with enhanced yields are presented in which a microorganism is engineered to enhance the conversion of a carbon source into n-butyraldehyde. The n-butyraldehyde is recovered by way of a gas stripping process that occurs during the conversion process, providing significantly greater product yield than post-fermentation recovery of n-butyraldehyde alone.

  • Patent number: 9550980
    Abstract: Healthcare costs are a significant worldwide, with many patients being denied medications because of their high prices. One approach to addressing this problem involves the biosynthesis of chiral drug intermediates, an environmentally friendly solution that can be used to generate pharmaceuticals at much lower costs than conventional techniques. In this context, embodiments of the invention comprise methods and materials designed to allow microorganisms to biosynthesize the nonnatural amino acid L-homoalanine. As is known in the art, L-homoalanine is a chiral precursor of a variety of pharmaceutically valuable compounds including the anticonvulsant medications levetiracetam (sold under the trade name Keppra®) and brivaracetam, as well as ethambutol, a bacteriostatic antimycobacterial drug used to treat tuberculosis. Consequently, embodiments of the invention can be used in low cost, environmentally friendly processes to generate these and other valuable compounds.

  • Patent number: 9481898
    Abstract: The disclosure provides a process that converts CO2 to higher alcohols (e.g. isobutanol) using electricity as the energy source. This process stores electricity (e.g. from solar energy, nuclear energy, and the like) in liquid fuels that can be used as high octane number gasoline substitutes. Instead of deriving reducing power from photosynthesis, this process derives reducing power from electrically generated mediators, either H2 or formate. H2 can be derived from electrolysis of water. Formate can be generated by electrochemical reduction of CO2. After delivering the reducing power in the cell, formate becomes CO2 and recycles back. Therefore, the biological CO2 fixation process can occur in the dark.
