Strains of bacillus for inhibiting foodborne pathogens
A process for inhibiting foodborne pathogens and reducing foodborne disease involves contacting a living animal, a dressed carcass, or a cut of meat with an effective amount of a bacillus strain exhibiting antibacterial activity. Strains of antibacterial bacillus that are particularly effective for inhibiting Vibrio were discovered. These include Bacillus licheniformis OBT 618 and Bacillus amyloliquefaciens OBT 712.
1. A process, comprising contacting a living animal, dressed carcass, or cut of meat with an effective amount of Bacillus licheniformis strain OBT 618 as deposited with the American Type Culture Collection under accession number PTA-122188 that exhibits antibacterial activity,
wherein the process is a process for producing a food product, and the effective amount is an amount for inhibiting at least one foodborne pathogen.
2. The process of claim 1 , in which the at least one foodborne pathogen is present in or on the living animal, dressed carcass, or cut of meat.
3. The process of claim 2 , in which the at least one foodborne pathogen comprises Salmonella enteric, Escherichia coli, Clostridium difficile, Vibrio , or a combination thereof.
4. The process of claim 2 , wherein the at least one foodborne pathogen is Salmonella enteric, Escherichia coli and/or Clostridium difficile.
5. The process of claim 4 , in which contacting the living animal, dressed carcass, or cut of meat with the Bacillus licheniformis strain OBT 618 is done by applying an aqueous based composition containing the Bacillus licheniformis strain OBT 618 to the live animal, dressed carcass, or cut of meat.
6. The process of claim 5 , in which the applying is done by spraying, brushing or dipping.
7. The process of claim 4 , in which the process is performed on a living animal, and the contacting is done by feeding the Bacillus licheniformis strain OBT 618 to the living animal.
8. The process of claim 4 , wherein the at least one foodborne pathogen is Salmonella enteric.
9. The process of claim 4 , wherein the at least one foodborne pathogen is Escherichia coli.
10. The process of claim 1 , in which contacting the living animal, dressed carcass, or cut of meat with the Bacillus licheniformis strain OBT 618 is done by applying an aqueous based composition containing the Bacillus licheniformis strain OBT 618 to the live animal, dressed carcass, or cut of meat.
11. The process of claim 10 , in which the applying is done by spraying, brushing or dipping.
12. The process of claim 1 , in which the process is performed on a living animal, and the contacting is done by feeding the Bacillus licheniformis strain OBT 618 to the living animal.
13. The process of claim 1 , in which the process is performed on a living animal, wherein the living animal is a fish or a shell fish contained in a tank holding water, and wherein the Bacillus licheniformis strain OBT 618 is added to the water in the tank in the form of spores.
14. The process of claim 13 , in which a concentration of Bacillus licheniformis strain OBT 618 spores in the water is from 10 5 to 10 7 spores/ml.
15. The process of claim 1 , comprising:
feeding the Bacillus licheniformis strain OBT 618 to a first animal; and
feeding the first animal to a second animal, thereby increasing the survivability of the second animal.
16. The process of claim 15 , in which the second animal is an aquatic animal and the first animal that is ted to the second animal is a rotifer.
