Philippe J. Dufresne 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).

  • Fungal cells and fermentation processes
    Patent number: 10407705
    Abstract: The present invention provides an isolated fungal cell that is capable of producing one or more biomass-degrading enzymes and that exhibits increased or decreased expression or copy number of a polynucleotide encoding a PtaB-like protein. Also provided is a fermentation processes for producing one or more biomass-degrading enzymes comprising a fungal cells exhibiting increased or decreased expression or copy number of a polynucleotide encoding a PtaB-like protein. The biomass-degrading enzymes produced by the isolate fungal cell and fermentation processes of the present invention may be used in a process to produce soluble sugars from biomass.

  • Modified yeast strains exhibiting enhanced fermentation of lignocellulosic hydrolysates
    Patent number: 8936929
    Abstract: The present invention relates to novel xylose-fermenting yeast strains (for example, yeast of the genus Saccharomyces, e.g., S. cerevisiae) with an enhanced ability to ferment the xylose (and/or another pentose sugar) present in a lignocellulosic hydrolysate to a fermentation product(s) (for example, an alcohol (e.g., ethanol) or a sugar alcohol (e.g., xylitol)).
