Patents by Inventor Peter Stougaard

Peter Stougaard 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).

  • Enzyme isolated from a Bifidobacterium
    Patent number: 6555348
    Abstract: The present invention concerns a new &bgr;-galactosidase with transgalactosylating activity isolated from Bifidobacterium bifidum and a truncated enzyme where the C-terminal end of the &bgr;-galactosidase protein has been deleted, resulting in an enzyme with a higher transgalactosylating activity than hydrolase activity. When lactose is used as a substrate, galacto-oligosaccharides are products of the transgalactosylase activity. Galacto-oligosaccharides enhance growth of health-promoting Bifidobacterium that may be used in a number of applications in the dairy industry.

  • Process for manufacturing of tagatose
    Publication number: 20030022844
    Abstract: Tagatose is manufactured by hydrolyzing lactose to galactose and glucose and isomerizing galactose to tagatose and chromatographic separation and recycling any unconverted compounds. Thereby high yields of pure tagatose are obtained.

  • Recombinant hexose oxidase, a method of producing same and use of such enzyme
    Publication number: 20020106725
    Abstract: A method of producing hexose oxidase by recombinant DNA technology, recombinant hexose oxidase and the use of such enzyme, in particular in the manufacturing of food products such as doughs and dairy products, animal feed, pharmaceuticals, cosmetics, dental care products and in the manufacturing of lactones. Suitable sources of DNA coding for the enzyme are marine algal species including Chondrus crispus, Iridophycus flaccidum and Euthora cristata. In useful embodiments, the recombinant hexose oxidase is produced by Pichia pastoris, Saccharomyces cerevisiae or E. coli.
