Leandro Vieira dos Santos 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).

  • Expression cartridge for the transformation of eukaryotic cells, method for transforming eukaryotic cells, genetically modified organism, method for producing biofuels and/or biochemicals, and thus produced biofuel and/or biochemical
    Patent number: 10155953
    Abstract: The present invention describes the expression cassette for transforming eukaryotic cell which comprises the peptide encoding non-natural sequence of nucleotides with xylose isomerase feature (SEQ ID NO: 1), optionally also comprising other genes of pentose phosphate route. Additionally, it is described the microorganism filed under the number DSM28739, which, in addition to the above-mentioned modifications, also present genetic modifications from adaptive evolution. The described microorganism shows efficient consumption of xylose and conversion of ethanol when compared to its correspondent without said genetic modifications and mutations from evolution. It is also described the process for producing biofuels e biochemicals, preferably ethanol, mainly from the lignocellulosic portion of the vegetal biomass. Biofuels, preferably ethanol, and biochemicals produced by the process of the invention are also described.
