  • Patent number: 11905513
    Abstract: Methods of genetically modifying microorganisms using advanced genome editing are disclosed. Methods of modifying the genome of these microorganisms for point mutations, deletions, and DNA insertions are also disclosed. Further, inhibiting expression of genes without manipulating the genome of the microorganism is disclosed. In some cases, the microorganism can be a methylotroph, e.g., a methanotroph.
    Type: Grant

    Date of Patent: February 20, 2024
    Assignee: MBP TITAN, LLC
    Inventors: Xuezhi Li, James Kealey, Kevin Lee Dietzel
  • Publication number: 20230051667
    Abstract: Genetically modified microorganisms that have the ability to convert carbon substrates into chemical products such as isobutanol are disclosed. For example, genetically modified methanotrophs that are capable of generating isobutanol at high titers from a methane source are disclosed. Methods of making these genetically modified microorganisms and methods of using them are also disclosed.

  • Publication number: 20220162656
    Abstract: Methods and systems are provided for producing codeinone within an engineered non-plant cell. The method comprises, within the engineered non-plant cell, producing a thebaine product. The method also comprises, within the engineered non-plant cell, contacting the thebaine product with an enzyme having thebaine 6-O-demethylase activity, thereby producing a neopinone product. Additionally, the method comprises, within the engineered non-plant cell, contacting the neopinone product with a neopinone isomerase, thereby producing a codeinone product.
