  • Microorganisms and methods for improved biological production of ethylene glycol
    Patent number: 11952607
    Abstract: The disclosure provides genetically engineered microorganisms and methods for improved biological production of ethylene glycol and precursors of ethylene glycol. The microorganism of the disclosure produces ethylene glycol or a precursor of ethylene glycol through one or more of 5,10-methylenetetrahydrofolate, oxaloacetate, citrate, malate, and glycine. The disclosure further provides compositions comprising ethylene glycol or polymers of ethylene glycol such as polyethylene terephthalate.
    Type: Grant
    Filed: August 5, 2022
    Date of Patent: April 9, 2024
    Assignee: LanzaTech, Inc.
    Inventors: Zachary Robert Cowden, Ching Leang, Michael Koepke, Rasmus Overgaard Jensen, Alexander Paul Mueller
  • MICROORGANISM WITH KNOCK-IN AT ACETOLACTATE DECARBOXYLASE GENE LOCUS
    Publication number: 20230348886
    Abstract: Provided herein is a genetically engineered microorganism comprising knock-in of DNA at an acetolactate decarboxylase gene locus. Replacement of the acetolactate decarboxylase gene with DNA encoding one or more native or nonnative enzymes confers certain advantages, including fermentation stability and increased production of native and nonnative products from gaseous substrates.
    Type: Application
    Filed: May 2, 2023
