Marcus Matheus Catharina Gielkens 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).

  • Cellulose degrading enzymes of aspergillus
    Publication number: 20040001904
    Abstract: Two cellobiohydrolase polypeptides (CBHA and CBHB) derived from Aspergillus are described and can be used to degrade cellulose. Variants of these peptides are described as well as DNA encoding the peptides, vectors and host cells. The peptides can be used to produce or process food, animal feed, wood pulp, paper and textiles.
    Type: Application
    Filed: February 28, 2003
    Publication date: January 1, 2004
