The present invention provides in one aspect for a method for controlling odor associated with spills of organic material which can cause odors on carpets. The method comprises applying to the carpet a preparation of dormant bacteria, which when activated are effective to control odors. The dormant bacterial preparation is allowed to become associated with the carpet, such that when the carpet is exposed to organic material which can cause odors, the bacteria are capable of becoming active and digesting the organic material. The formulation may contain other agents such as odor neutralizing or masking agents, enzymes, foaming or anti-foaming agents.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. An aqueous odor controlling bacterial composition for treating a surface, the composition selected from the group consisting of composition (A) and composition (B), wherein said composition (A) includes: (i) bacteria spores, which become active when exposed to an odor-causing organic material and which, upon activation, are capable of digesting said odor-causing organic material; and (ii) an adhering agent, which is at least one selected from the group consisting of a fluorochemical, an acrylic co-polymer, a styrene butadiene rubber, a nitrile rubber, a polyvinyl chloride, and a stain blocker selected from the group consisting of a sulfonated phenol formaldehyde condensate polymer, a sulfonated naphthol formaldehyde condensate polymer, and a hydrolyzed vinyl aromatic maleic anhydride polymer, in an amount sufficient to adhere said bacteria to said surface upon application of said bacterial composition thereto and to allow said bacteria to remain adhered to said surface such that said bacteria can be exposed to said odor-causing organic material and become active, and wherein composition (B) consists essentially of: (i) bacteria spores, which become active when exposed to an odor-causing organic material and which, upon activation, are capable of digesting said odor-causing organic material; (ii) at least one adhering agent in an amount sufficient to adhere said bacteria to said surface upon application of said bacterial composition thereto and to allow said bacteria to remain adhered to said surface such that said bacteria can be exposed to said odor-causing organic material and become active; and, optionally, (iii) at least one odor neutralizing or odor trapping agent. 2. The composition according to claim 1, comprising said composition (A). 3. The composition according to claim 1, which is said composition (B). 4. The composition according to claim 3, wherein said adhering agent is at least one selected from the group consisting of a fluorochemical, a stain blocker, an acrylic co-polymer, a styrene butadiene rubber, a nitrile rubber and a polyvinyl chloride. 5. The composition according to claim 4, wherein said adhering agent is said fluorochemical. 6. The composition according to claim 2, wherein said adhering agent is said fluorochemical. 7. The composition according to claim 2, wherein said adhering agent is said stain blocker. 8. The composition according to claim 4, wherein said adhering agent is said stain blocker. 9. The composition according to claim 8, wherein said stain blocker is selected from the group consisting of sulfonated phenol formaldehyde condensate polymer, sulfonated naphthol formaldehyde condensate polymer, and hydrolyzed vinyl aromatic male anhydride polymer. 10. The composition according to claim 2, wherein said adhering agent is said acrylic co-polymer. 11. The composition according to claim 4, wherein said adhering agent is said acrylic co-polymer. 12. The composition according to claim 2, wherein said adhering agent constitutes between 0.01 wt % and 20 wt % of said composition based upon a total weight of said composition. 13. The composition according to claim 3, wherein said adhering agent constitutes between 0.01 wt % and 20 wt % of said composition based upon a total weight of said composition. 14. The composition according to claim 12, wherein said adhering agent constitutes between 0.1 wt % and 15 wt % of said composition. 15. The composition according to claim 13, wherein said adhering agent constitutes between 0.1 wt % and 15 wt % of said composition. 16. The composition according to claim 14, wherein said adhering agent constitutes between 5 wt % and 10 wt % of said composition. 17. The composition according to claim 15, wherein said adhering agent constitutes between 5 wt % and 10 wt % of said composition. 18. The composition according to claim 2, further comprising at least one odor neutralizing or odor trapping agent. 19. The composition according to claim 3, comprising said at least one odor neutralizing or odor trapping agent. 20. The composition according to claim 18, wherein said odor neutralizing or odor trapping agent is sodium bicarbonate or molecular sieves. 21. The composition according to claim 19, wherein said odor neutralizing or odor trapping agent is sodium bicarbonate or molecular sieves. 22. The composition according to claim 2, wherein said bacteria are of the genus Bacillus. 23. The composition according to claim 3, wherein said bacteria are of the genus Bacillus. 24. The composition according to claim 22, wherein said bacteria of the genus Bacillus is one or more strains selected from the group of bacterial species consisting of Bacillus megaterium, Bacillus pasteurii, Bacillus laevolacticus and Bacillus amyloliquefaciens. 25. The composition according to claim 23, wherein said bacteria of the genus Bacillus is one or more strains selected from the group of bacterial species consisting of Bacillus megaterium, Bacillus pasteurii, Bacillus laevolacticus and Bacillus amyloliquefaciens.
