Armel Guyonvarch 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).

  • Process for the fermentative preparation of metabolic products and for the nucleotide sequences encoding for the sod gene
    Patent number: 6569650
    Abstract: The present invention is directed to nucleotide sequences coding for the superoxide dismutase (sod) gene from Corynebacterium melassecola. It includes processes for the fermentative preparation of nucleotides, vitamins and L-amino acids using coryneform bacteria in which the sod gene is amplified.
    Type: Grant
    Filed: August 13, 1999
    Date of Patent: May 27, 2003
    Assignee: Degussa AG
    Inventors: Muriel Merkamm, Armel Guyonvarch, Achim Marx

  • System for protein expression and secretion especially in corynebacteria
    Patent number: 6027920
    Abstract: A DNA cassette for expression and secretion of a given amino acid, polypeptide or protein in a host strain of corynebacterium, including a sequence which encodes the amino acid, polypeptide or protein, and a region of chromosomal or plasmid DNA, wherein the sequence is situated in the region of chromosomal or plasmid DNA such that the sequence is transcribed with, at the sequence's 5' end, at least one portion of a sequence encoding the signal sequence of the protein PS1 or PS2, the at least one portion ensuring the secretion of the amino acid, polypeptide or protein after translation when the DNA cassette is incorporated into the host strain of corynebacterium.
