  • Method of purifying a hydrophobin present in a hydrophobin-containing solution
    Patent number: 6903191
    Abstract: The invention relates to a method of purifying a hydrophobin present in a hydrophobin-containing solution. According to the invention the solution is contacted with a surface for the adsorption to that surface, and separated from a solution depleted in hydrophobin. Subsequently the surface is contacted with a solution containing a surfactant at a temperature lower than 90° C. Desorbed hydrophobin is separated from said surface.
    Type: Grant
    Filed: February 2, 2001
    Date of Patent: June 7, 2005
    Assignee: Applied NanoSystems B.V.
