Abstract
Hydrophobins for stabilizing phases in biphasic liquid systems.
Claims11
A process for stabilizing liquid phases in a composition comprising at least two liquid phases, wherein the process comprises adding to the composition a hydrophobin to comprise from 0.001 ppm to 80 ppm of the composition, and wherein the composition comprises:
- a) oil and water;
- or
- b) fuel and water,
- wherein the hydrophobin is a fusion hydrophobin or a derivative thereof, and the fusion hydrophobin is selected from the group consisting of yaad-Xa-dewA-his (SEQ ID NO:
- 20), yaad-Xa-rodA-his (SEQ ID NO:
- 22) and yaad-Xa-basf1-his (SEQ ID NO:
- 24), where yaad may be a truncated fusion partner yaad' having from 20 to 293 amino acids,
- and wherein addition of the hydrophobin to the composition stabilizes the liquid phases as compared to a composition without the addition of the hydrophobin.
A formulation comprising at least one organic phase consisting of a fuel and crude oil, the formulation further comprising an aqueous phase comprising a hydrophobin or a derivative thereof comprising from 0.001 ppm to 80 ppm of the overall formulation, wherein hydrophobin is a fusion hydrophobin or a derivative thereof, and the fusion hydrophobin is selected from the group consisting of yaad-Xa-dewA-his (SEQ ID NO:
- 20), yaad-Xa-rodA-his (SEQ ID NO:
- 22) and yaad-Xa-basf1-his (SEQ ID NO:
- 24), where yaad may be a truncated fusion partner yaad' having from 20 to 293 amino acids.
A process for stabilizing phase separation in a composition comprising water/oil or water/fuel mixture, comprising:
- a) adding a hydrophobin to an emulsion of a composition comprising water/oil or water/fuel mixture, and allowing the emulsion to separate into at least two liquid phases;
- or
- b) allowing an emulsion of a composition comprising water/oil or water/fuel mixture to separate into at least one aqueous phase and at least one other liquid phase, and adding a hydrophobin to the at least one aqueous phase,
- wherein the hydrophobin is added to the emulsion or the at least one aqueous phase in an amount of from 0.001 ppm to 80 ppm of the composition, wherein the hydrophobin is a fusion hydrophobin or a derivative thereof and wherein the fusion hydrophobin is selected from the group consisting of yaad-Xa-dewA-his (SEQ ID NO:
- 20), yaad-Xa-rodA-his (SEQ ID NO:
- 22) and yaad-Xa-basf1-his (SEQ ID NO:
- 24), where yaad may be a truncated fusion partner yaad' having from 20 to 293 amino acids.
