Patents by Inventor Marie-Christine Fournier

Marie-Christine Fournier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Modified cellulases with increased thermostability, thermophilicity, and alkalophilicity
    Patent number: 8101398
    Abstract: A modified Family 6 cellulase enzyme comprising a proline residue at position 413 is provided. Genetic constructs and genetically modified microbes comprising DNA sequences encoding the modified Family 6 cellulase are also provided. Family 6 cellulases of the invention display improved thermostability, thermophilicity, alkalophilicity, or a combination thereof, relative to the parent Family 6 cellulases. Such cellulases find use in a variety of applications in industry that require cellulase stability and activities at temperatures, pH values, or both, above that of the native enzyme.
    Type: Grant
    Filed: June 23, 2010
    Date of Patent: January 24, 2012
    Assignee: Iogen Energy Corporation
    Inventors: Patrick St-Pierre, Nabil Masri, Marie-Christine Fournier, Theresa C. White
