Abstract

The invention relates to malodor controlling bacteria and related methods and compositions for the control and prevention of malodor.

First claim

We claim:

1. A method of inhibiting or reducing production of laundry malodor caused by at least one malodor causing bacteria comprising contacting a fabric or a laundry washing machine with a Bacillus strain having the deposit accession number NRRL B-50136, which inhibits or reduces production of malodor caused by the at least one malodor causing bacteria.

2. The method of claim 1 , wherein the method comprises contacting the at least one malodor causing bacteria with the Bacillus strain.

3. The method of claim 1 , wherein the method comprises contacting an odor generating compound derived from the at least one malodor causing bacteria with the Bacillus strain.

4. The method of claim 1 , wherein the contacting comprises administering the Bacillus strain to a laundry washing machine.

5. The method of claim 1 , wherein the contacting is done during a washing process.

6. The method of claim 1 , wherein the contacting is done to a new washing machine.

7. The method of claim 1 , wherein the contacting is done to a washing machine following one or more uses of said washing machine.

8. The method of claim 1 , wherein the at least one malodor causing bacteria is at least one bacterial species selected from the group consisting of Bacillus amyloliquefaciens, Acinetobacter junii, Bacillus subtilis, Janibacter melois, Sphingobium ummariense, Sphingomonas panni, Sphingomonadaceae sp., Actinobacter tandoii, Junibacter melonis, Curtobacterium flaccumfaciens, Flavobacterium denitrificans, Staphylococcus epidermidis, Escherichia coli, Leclercia adecarboxylata, Enterobacter sp., Cronobacter sakazakii, Bacillus megaterium, Sphingobacterium faecium, Enterobacter cloacae, Pseudomonas veronii, Microbacterium luteolum, Morganella morganii, Bacillus cereus, Pseudomonas sp., Pseudomonas - marginalis, Citrobacter sp., Escherichia coli strain JCLys5 , Roseomonas aquatic, Pseudomonas panipatensis, Brevibacillus subtilis subtilis, Micrococcus luteus, Bacillus pumilus, Ralstonia eutropha, Caulobacter fusiformis, Stenotrophomonas maltophilia, Rhodococcus opacus, Breviundimonas intermedia, Agrobacterium tumefaciens , and combinations thereof.

9. A method of inhibiting the production of laundry malodor caused by a bacterium, comprising contacting a laundry washing machine with a Bacillus strain, in combination with or formulated as a washing product, which inhibits the production of malodor caused by the at least one bacterium that causes laundry malodor; wherein the Bacillus strain is a strain having the deposit accession number NRRL B-50136; wherein the bacterium is selected from the group consisting of Bacillus subtilis, Sphingobium ummariense, Sphingomonas panni, Sphingomonas ursinicola, Acinetobacter tandoii, Acinetobacter junii, Curtobacterium flaccumfaciens, Janibacter melonis, Pseudomonas sp., Flavobacterium denitrificans, Micrococcus luteus, Bacillus pumilus, Ralstonia eutropha, Caulobacter fusiformis, Stenotrophomonas maltophilia, Micrococcus luteus, Rhodococcus opacus, Breviundimonas intermedia, Agrobacterium tumefaciens and a combination thereof.

10. The method of claim 9 , wherein the method comprises contacting the at least one bacterium that causes laundry malodor.

11. The method of claim 9 , wherein the method comprises contacting an odor generating compound obtained from the at least one bacterium capable of causing odor.

12. The method of claim 9 , wherein the contacting is done during a washing process.

13. The method of claim 9 , wherein the contacting is done to a new washing machine.

14. The method of claim 9 , wherein the contacting is done to a washing machine following one or more uses of said washing machine.
