  • Recombinant peptide
    Patent number: 7297516
    Abstract: Use of a polypeptide or protein with amino acid sequence corresponding substantially to AFP-type III HPLC 12 as additive in a product for improvement of said product, said improvement residing in improved properties of modification of ice crystal growth processes influencing size and shape characteristics of ice in particular in regrowth thereby e.g. minimising potential freezing damage e.g. by preventing or inhibiting ice recrystallisation of the product upon freezing, said use occurring in a manner known per se for anti freeze peptides to obtain higher specific modification activity in particular antifreeze activity than obtainable with the same amount of Winter Flounder AFP.
    Type: Grant
    Filed: September 3, 2004
    Date of Patent: November 20, 2007
    Assignee: Good Humor - Breyer Ice Cream, division of Conopco, Inc.
    Inventors: John William Chapman, Wouter Musters, Pieter Dirk van Wassenaar

  • Enzymatic detergent compositions
    Patent number: 5877139
    Abstract: There is provided an enzymatic detergent composition comprising one or more surfactants and an endoglucanase which is not a Family 7 cellulase, which contains no cellulose binding domain and wherein the catalytic domain contains at least two disulphide bridges. Preferably, the endoglucanase is producible from Thermomonospora fusca, or mutants or variants thereof.
    Type: Grant
    Filed: November 20, 1996
    Date of Patent: March 2, 1999
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
