Maria E. Suykerbuyk 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).

  • Cloning and expression of DNA encoding a ripening form of a polypeptide having rhamnogalacturonase activity
    Patent number: 6013489
    Abstract: The invention relates to isolation of an Aspergillus gene encoding rhamnogalacturonase (RG-ase) and the construction of recombinant Aspergillus strains with overexpression of RG-ase. These strains can be used for the commercial production of RG-ase. RG-ase is an important enzyme in processes requiring the degradation and/or modification of pectin or modification of pectin-containing vegetable or plant cell wall material. RG-ase may be used in various applications, including the processing of fruits and vegetables, in the extraction of components from vegetable material or for improving the functionality of pectin or pectin-containing vegetable material, food material or plant cell wall material.
    Type: Grant
    Filed: September 29, 1995
    Date of Patent: January 11, 2000
    Inventors: Wouter Musters, Hein Stam, Maria E. Suykerbuyk, Jacob Visser, Johannes M. Verbakel
