Abstract

See full text

The present invention relates to designed polypeptide biosurfactants that may be prepared by recombinant technology in commercially useful amounts and purified by simple non-chromatographic methods. The designed polypeptide biosurfactants comprise at least one stimuli-responsive amino acid residue or at least one glutamine or asparagine residue and may be useful in modulating the stability of a foam, alone or in combination with an α-helical peptide. The designed polypeptide biosurfactant may be useful in the formation and collapse of foams in foods, beverages, pharmaceuticals, personal care products, cosmetics, cleaning products, mineral recovery, bioremediation, oil recovery and laundry products. The designed biosurfactants may also be useful in recombinant production and purification of peptides, polypeptides and proteins.
