Claims
- 1. A method of cleaning, disinfecting or inhibiting microbial growth on a hard surface, wherein the surface is contacted with a composition comprising a haloperoxidase, a hydrogen peroxide source, a halide source, and an ammonium source of the formula:
2
- 2. The method of claim 1, wherein the haloperoxidase is obtainable from fungi, bacteria, or algae.
- 3. The method of claim 2, wherein the haloperoxidase is obtainable from a fungus selected from the group consisting of Caldariomyces, Alternaria, Curvularia, Drechslera, Ulocladium and Botrytis.
- 4. The method of claim 3, wherein the haloperoxidase is obtainable from Curvularia.
- 5. The method of claim 4, wherein the haloperoxidase is obtainable from Curvularia verruculosa.
- 6. The method of claim 5, wherein the haloperoxidase is obtainable from Curvularia verruculosa CBS 147.63, or the haloperoxidase is immunologically cross-reactive with the haloperoxidase obtainable from Curvularia verruculosa CBS 147.63.
- 7. The method of claim 2, wherein the haloperoxidase is obtainable from a bacterium selected from the group consisting of Pseudomonas and Streptomyces.
- 8. The method of claim 1, wherein the haloperoxidase is a Vanadium peroxidase.
- 9. The method of claim 1, wherein the haloperoxidase is a chloride peroxidase or a bromide peroxidase.
- 10. The method of claim 1, wherein the source of hydrogen peroxide is hydrogen peroxide, or a hydrogen peroxide precursor, or a hydrogen peroxide generating enzyme system, or a peroxycarboxylic acid or a salt thereof.
- 11. The method of claim 1, wherein the halide source is a halide salt.
- 12. The method of claim 11, wherein the halide source is sodium chloride, potassium chloride, sodium bromide, potassium bromide, sodium iodide, or potassium iodide.
- 13. The method of claim 1, wherein the ammonium source is an ammonium salt.
- 14. The method of claim 13, wherein the ammonium source is diammonium sulphate, ammonium chloride, ammonium bromide, or ammonium iodide.
- 15. The method of claim 1, wherein the ammonium source is an aminoalcohol.
- 16. The method of claim 1, wherein said composition is an aqueous composition.
- 17. The method of claim 16, wherein the concentration of the haloperoxidase is in the range of from 0.01-100 mg enzyme protein per liter.
- 18. The method of claim 16, wherein the concentration of the hydrogen peroxide source corresponds to 0.01-1000 mM.
- 19. The method of claim 16, wherein the concentration of the halide source corresponds to 0.01-1000 mM.
- 20. The method of claim 16, wherein the concentration of the ammonium source corresponds to 0.01-1000 mM.
- 21. The method of claim 1, wherein the composition is a granulate.
- 22. The method of claim 1, wherein the hard surface is a process equipment such as a member of a cooling tower, a water treatment plant, a dairy, a food processing plant, a chemical or pharmaceutical process plant.
- 23. The method of claim 22, wherein the hard surface is a surface of water sanitation equipment.
- 24. The method of claim 23, wherein the hard surface is a surface of equipment for paper pulp processing.
