Abstract

The present invention relates to an antimicrobial composition having activity against Gram-positive and Gram-negative bacteria. The composition is a) a composition comprising at least two organic acids selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid; b) a composition comprising at least two bacteriocin selected from the group consisting of pediocin, Nisin and reuterin; c) a composition comprising pediocin and at least two organic acids selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid; or d) a composition comprising reuterin and at least one organic acid selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid. The present invention also relates to the use of said compositions for sanitizing and/or disinfecting surfaces and method thereof.

First claim

What is claimed is:

1. An antimicrobial composition comprising about 200 AU/ml of pediocin, about 0.5% by weight or volume lactic acid and about 1.0% by weight or volume of citric acid.

2. The antimicrobial composition of claim 1 , wherein the antimicrobial composition has an antimicrobial activity against Gram-positive and Gram-negative bacteria.

3. The antimicrobial composition of claim 2 , wherein the Gram-positive bacteria is Enterococcus faecium, Staphylococcus aureus, Listeria monocytogenes Scott 3 , Corynebacterium, Streptococcus M3 , Streptococcus agalactiae, Streptococcus sp, or Clostridium difficile.

4. The antimicrobial composition of claim 2 , wherein the Gram-negative bacteria is Aeromonas, Escherichia coli O 157:H7 , Escheria coli, Pseudomonas fluorescens, Serratia marcescens, Salmonella sp, Pseudomonas aeroginosa, Pseudomonas euroginosa, Erwinia, Yersinia enterocolitica or Aeromonas Hydrophila.

5. The composition of any claim 1 , wherein the pediocin is pediocin PA-1.

6. The antimicrobial composition of claim 1 , further comprising a surfactant.

7. The antimicrobial composition of claim 1 in form of a foam, ointment, gel, liquid, spray or powder.

8. A cellulosic substrate comprising the antimicrobial composition as defined in claim 1 .

9. A food packaging comprising the antimicrobial composition as defined in claim 1 .

10. The food packaging of claim 9 , wherein the food packaging is a film, resin, liner, absorbent pad, plastic, shrink bag, shrink wrap, plastic wrap, Styrofoam™, carton, or cellulosic substrate.

11. A method for sanitizing and/or disinfecting a surface, comprising applying an effective antimicrobial amount of the antimicrobial composition as defined in claim 1 to the surface.

12. The method of claim 11 , wherein the surface is the surface of an object, food, food plant, a body part or a food packaging.

13. The method of claim 12 , wherein the food packaging is a film, resin, liner, absorbent pad, plastic, shrink bag, shrink wrap, plastic wrap, Styrofoam™, carton, or cellulosic substrate.
