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.
