Abstract

Compositions and methods for protection against bacterial contamination are disclosed Antibacterial proteins and methods of use thereof are also disclosed.

Claims (21)

1. An isolated nucleic acid sequence encoding an antibacterial protein, the isolated nucleic acid sequence comprising SEQ ID NO: 5.

2. An isolated amino acid sequence comprising an antibacterial protein, the isolated amino acid sequence comprising SEQ ID NO: 10.

3. A population of cells, wherein at least one cell expresses at least one antibacterial protein that is encoded by a nucleic acid sequence comprising SEQ ID NO: 5.

4. The population of cells of claim 3 , wherein the population of cells are yeast.

5. The population of cells of claim 4 , wherein the yeast is selected from the group consisting of Kluyveromyces lactis, Saccharomyces cerevisiae, Schizosaccharomyces pombe , and Candida albicans.

6. A population of cells, wherein at least one cell expresses at least one antibacterial protein having an amino acid sequence comprising SEQ ID NO: 10.

7. The population of cells of claim 6 , wherein the population of cells are yeast.

8. The population of cells of claim 7 , wherein the yeast is selected from the group consisting of Kluyveromyces lactis, Saccharomyces cerevisiae, Schizosaccharomyces pombe , and Candida albicans.

9. An isolated microscopic transgenic organism, wherein the isolated microscopic organism expresses at least one antibacterial protein that is encoded by a nucleic acid sequence comprising SEQ ID NO: 5.

10. The transgenic organism of claim 9 , wherein the antibacterial protein is expressed in response to lactic acid.

11. The transgenic organism of claim 9 , wherein the antibacterial protein is expressed in response to ethanol.

12. The transgenic organism of claim 9 , wherein the isolated transgenic organism is a yeast strain.

13. The transgenic organism of claim 12 , wherein the yeast strain is selected from the group consisting of Kluyveromyces lactis, Saccharomyces cerevisiae, Schizosaccharomyces pombe , and Candida albicans.

14. An isolated bactericidal yeast, wherein the yeast expresses at least one antibacterial protein that is encoded by a nucleic acid sequence comprising SEQ ID NO: 5.

15. The isolated bactericidal yeast of claim 14 , wherein the yeast is selected from the group consisting of Kluyveromyces lactis, Saccharomyces cerevisiae, Schizosaccharomyces pombe , and Candida albicans.

16. The isolated bactericidal yeast of claim 14 , wherein the antibacterial protein is expressed in response to lactic acid.

17. The isolated bactericidal yeast of claim 14 , wherein the antibacterial protein is expressed in response to ethanol.

18. An isolated bactericidal yeast, wherein the yeast expresses at least one antibacterial protein having an amino acid sequence comprising SEQ ID NO: 10.

19. The isolated bactericidal yeast of claim 18 , wherein the yeast is selected from the group consisting of Kluyveromyces lactis, Saccharomyces cerevisiae, Schizosaccharomyces pombe , and Candida albicans.

20. The isolated bactericidal yeast of claim 18 , wherein the antibacterial protein is expressed in response to lactic acid.

21. The isolated bactericidal yeast of claim 18 , wherein the antibacterial protein is expressed in response to ethanol.
