Rudolf G. M. Luiten 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).

  • Propionibacteruim vector
    Patent number: 6830901
    Abstract: An endogenous plasmid of Propionibacterium is described, isolated from Propionibacteria freudenreichii LMG 16545 (deposited as CBS 101022), and its sequence provided. This plasmid can be used to transform Propionibacteria to express homologous or heterologous proteins, in the production of recombinant proteins or products of enzymes, for example vitamin B12.
    Type: Grant

  • 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.

  • Glucose isomerase enzymes and their use
    Patent number: 5376536
    Abstract: New mutant glucose isomerases are provided exhibiting improved properties under application conditions. These glucose isomerases are obtained by expression of a gene encoding said enzyme, having an amino acid sequence which differs at least in one amino acid from the wildtype glucose isomerase. Preferred mutant enzymes are those derived from Actinoplanes missouriensis glucose isomerase.
