Abstract

Disclosed are methods of removing oil from an aqueous surface, comprising: surrounding an oil spot on the aqueous surface with an oil-absorbing material; and introducing a solution comprising a surfactant to the oil spot. Also disclosed are the above methods where the oil is not mechanically directed towards the oil-absorbing material, or where the oil-absorbing material is not mechanically directed towards the oil. Also disclosed are the above methods further comprising introducing a solution comprising a protein/surfactant complex to the oil spot, where the protein/surfactant complex comprises a protein component obtained from the fermentation of yeast, comprising a mixture of multiple intracellular proteins, at least a portion of the mixture including yeast polypeptides obtained from fermenting yeast and yeast stress proteins resulting from subjecting a mixture obtained from the yeast fermentation to stress.

Claims (23)

1. A method of removing oil from an aqueous surface, the method comprising:

surrounding an oil spot on the aqueous surface with an oil-absorbing material; and

introducing a solution comprising a protein/surfactant complex to the oil spot, wherein the protein/surfactant complex comprises a protein component obtained from the fermentation of yeast, wherein the protein component comprises a mixture of multiple intracellular proteins, at least a portion of the mixture including yeast polypeptides obtained from fermenting yeast and yeast stress proteins resulting from subjecting a mixture obtained from the yeast fermentation to stress.

2. The method of claim 1 , wherein, after the surrounding step, the method does not include the step of mechanically directing the oil towards the oil-absorbing material, or the step of mechanically directing the oil-absorbing material towards the oil.

3. The method of claim 1 , wherein the oil-absorbing material is made from a material selected from the group consisting of sponge, hair, hay, and absorbent polymers.

4. The method of claim 1 , wherein the oil-absorbing material is contained in a water and oil permeable casing.

5. The method of claim 4 , wherein the casing is configured to allow contaminated water and oil to come into contact with the oil-absorbing material, but not to allow the oil-absorbing material to escape the casing.

6. The method of claim 1 , wherein the protein component is from aerobic fermentation of yeast.

7. The method of claim 1 , wherein the protein component comprises proteins obtained from exposing a product obtained from the fermentation of yeast to additional procedures that increase the yield of proteins produced from the process.

8. The method of claim 1 , wherein the protein component comprises proteins obtained from exposing a product obtained from the fermentation of yeast to an additional procedure selected from the group consisting of heat shock of the fermentation product, physical and/or chemical disruption of the yeast cells to release additional polypeptides, and lysing of the yeast cells.

9. The method of claim 1 , wherein the protein component comprises proteins obtained from exposing a product obtained from the fermentation of yeast to heat shock conditions.

10. The method of claim 1 , wherein the protein component comprises proteins obtained from physically disrupting the yeast after the fermentation of the yeast.

11. The method of claim 1 , wherein the protein component comprises proteins obtained from chemically disrupting the yeast after the fermentation of the yeast.

12. The method of claim 1 , wherein the protein component comprises proteins obtained from lysing the yeast after the fermentation of the yeast.

13. The method of claim 1 , wherein the surfactant has strong affinity to water, and weak affinity to oil, thereby preventing an oil dispersion effect.

14. The method of claim 1 , wherein the surfactant is selected from the group consisting of nonionic surfactants, anionic surfactants, amphoteric surfactants, cationic surfactants, and a combination thereof.

15. The method of claim 1 , wherein the surfactant is non-petroleum based.

16. The method of claim 1 , wherein the solution comprising the surfactant is injected into the center of the oil spot.

17. A method of removing oil from an aqueous surface, the method comprising:

surrounding an oil spot on the aqueous surface with an oil-absorbing material; and

introducing a solution comprising a protein/surfactant complex to the oil spot, wherein the protein/surfactant complex comprises a protein component obtained from the fermentation of yeast, wherein the protein component comprises a mixture of multiple intracellular proteins, at least a portion of the mixture including yeast polypeptides obtained from fermenting yeast and yeast stress proteins resulting from subjecting a mixture obtained from the yeast fermentation to stress,

wherein the oil is not mechanically directed towards the oil-absorbing material, or

wherein the oil-absorbing material is not mechanically directed towards the oil.
