Patents by Inventor Margareta A. Herweijer

Margareta A. Herweijer 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).

  • Alkaliphilic and thermophilic microorganisms and enzymes obtained therefrom
    Publication number: 20040033580
    Abstract: The present invention provides thermophilic alkaliphilic bacteria and thermostable alkaline polypeptides obtainable therefrom. It also provides a method for producing polypeptides according to the invention, nucleic acids encoding such polypeptides and compositions comprising such polypeptides. It also relates to the use of enzymes obtainable from these novel organisms in the detergent industry, the paper and pulp industry and the textile industry.
    Type: Application

    Publication date: February 19, 2004
    Inventors: Brain E. Jones, Margareta A. Herweijer, Michael J. Danson, David W. Hough, Carl R. Thompson
  • Cleaning compositions containing plant cell wall degrading enzymes and their use in cleaning methods
    Patent number: 6602842
    Abstract: Novel cleaning compositions comprising cell wall degrading enzymes are disclosed having pectinases and/or hemicellulases and optionally cellulases. The compositions are particularly suitable for removing stains of vegetable origin, especially from textiles. Although compositions having only one type of such enzymes axe part of the invention (excluding cellulases alone), preferred embodiments have a mixture of cell wall degrading enzyme activities to allow for a concerted action against the fibrous mass which usually constitutes a stain of vegetable origin.

  • Cleaning compositions containing plant cell wall degrading enzymes and their use in cleaning methods
    Patent number: 5872091
    Abstract: This invention relates to a laundry detergent composition as well as a method of laundrying fabric or soiled garments in which the composition requires a surfactant, a pectinase enzyme, a specific hemicellulase enzyme or enzymes, a cellulase enzyme, and additional component which includes bleaching agents, builders, an amylase enzyme and/or a protease enzyme.

  • Recombinant DNA encoding neutral trehalase
    Patent number: 5312909
    Abstract: A transformed yeast is disclosed, comprising at least one gene encoding neutral trehalase or trehalose-6-phosphate synthase which gene has been modified such that it differs from a corresponding wild-type gene encoding neutral trehalase or trehalose-6-phosphate synthase, the yeast having as a result a different trehalose content from the untransformed parent yeast. The sugar resistance and drying resistance of the yeast compared to those of the untransformed strain are thereby improved.
