  • Patent number: 10329590
    Abstract: There is provided a method of producing aminohexanoic acid and/or aminohexanoic acid ester from synthesis gas, the method comprising: A. contacting the synthesis gas with at least one bacteria capable of carrying out the Wood-Ljungdahl pathway and the ethanol-carboxylate fermentation to produce hexanoic acid; and B. contacting the hexanoic acid with a genetically modified cell to produce aminohexanoic acid and/or aminohexanoic acid ester, wherein the genetically modified cell has an increased activity, in comparison with its wild type, of alkane monooxygenase, alcohol dehydrogenase, and ?-transaminase.
    Type: Grant
    Filed: May 5, 2015
    Date of Patent: June 25, 2019
    Assignee: Evonik Degussa GmbH
    Inventors: Thomas Haas, Eva-Maria Eckl, Simon Beck
  • Patent number: 9765370
    Abstract: A process for producing alanine, including culturing a cell under aerobic conditions in an aqueous phase in the presence of an inorganic nitrogen source, and then contacting the aqueous phase and the cell cultured in the aqueous phase with a hydrophobic organic phase. The cell is a prokaryotic or a lower eukaryotic cell and expresses a recombinant alanine dehydrogenase.

  • Publication number: 20170260552
    Abstract: There is provided a mixed culture of a first and second microorganism in an aqueous medium, wherein the first microorganism is an acetogenic microorganism capable of converting a carbon source comprising CO and/or CO2 to acetate and/or ethanol, the second microorganism is a non-acetogenic microorganism capable of metabolising acetate and/or ethanol and the first and second microorganisms are in a homogenous mixture and wherein the aqueous medium comprises oxygen. There is also provided a method of producing substituted and/or unsubstituted organic compounds using the mixed culture.

  • Publication number: 20150111254
    Abstract: The problem addressed by the invention is solved in a first aspect by a method for producing alanine or a compound produced using alanine, having the steps of (a) providing a cell which expresses a recombinant alanine dehydrogenase or a variant thereof, (b) cultivating the cell under aerobic conditions in the presence of an inorganic nitrogen source in an aqueous phase, and (c) bringing the cell into contact with an organic phase, said cell being a prokaryotic or a lower eukaryotic cell.
