Patents by Inventor Gerardus C. M. Selten

Gerardus C. M. Selten 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).

  • Use of homologous amdS genes as selectable markers
    Publication number: 20040005692
    Abstract: The present invention discloses novel amdS genes from fungi previously not known to contain and amdS gene, such as Aspergillus niger and Penicillium chrysogenum. The novel amdS genes can be used as homologous selectable marker genes in the transformation of these fungi. Alternatively, the cloned amdS genes can be used to inactivate the endogenous copy of the gene in order to reduce the background in transformation experiments.

  • Cloning and expression of microbial phytase
    Publication number: 20030119163
    Abstract: A nucleotide sequence encoding phytase has been isolated and cloned. The coding sequence has been inserted into an expression construct which in turn has been inserted into a vector capable of transforming a microbial expression host. The transformed microbial hosts may be used to economically produce phytase on an industrial scale. The phytase produced via the present invention may be used in a variety of processes requiring the conversion of phytate to inositol and inorganic phosphate.

  • Polynucleotides encoding Aspergillus Niger and Penicillium Chrysogenum acetamidases and methods of use as selectable markers
    Patent number: 6548285
    Abstract: The present invention discloses novel amdS genes from fungi previously not known to contain an amdS gene, such as Aspergillus niger and Penicllium chrysogenum. The novel amdS genes can be used as homologous selectable marker genes in the transformation of these fungi. Alternatively, the cloned amdS genes can be used to inactivate the endogenous copy of the gene in order to reduce the background in transformation experiments.
