## Abstract

A method for suppressing the formation of ammonia comprising providing a carrier material to a container having a headspace; providing a bacteria and an odor inhibitor to the carrier material, the bacteria comprising Staphylococcus-xylosus and/or Staphylococcus-cohnii bacteria, and the odor inhibitor comprising an aminopolycarboxylic acid compound and a polyprotic acid compound, wherein at least one of the aminopolycarboxylic acid compound or the polyprotic acid compound is the salt form of the acid; and applying animal waste to the carrier material; wherein there is a 5 to 98 percent improvement of ammonia content in the headspace as compared to an untreated control comprising a container containing the carrier material and the bacteria and not contain the odor inhibitor. An ammonia suppressing composition.

## Claims

### Claim 1

A method for suppressing the formation of ammonia comprising:
providing a carrier material to a container having a headspace;
providing a bacteria and an odor inhibitor to the carrier material, and the odor inhibitor comprising an aminopolycarboxylic acid compound and a polyprotic acid compound, wherein at least one of the aminopolycarboxylic acid compound or the polyprotic acid compound is the salt form of the acid; and
applying animal waste to the carrier material; wherein there is a 5 to 98 percent improvement of ammonia content in the headspace as compared to an untreated control comprising a container containing the carrier material and the bacteria and not contain the odor inhibitor.

### Claim 2 (depends on 1)

The method of claim 1, the method further comprising: providing an additive material to the carrier material, wherein the additive material comprises diatomite, talc, gypsum, calcium carbonate, sand, glass, dirt, alumina, alumina-silicates, silicates, microbial control agents, colorants, fragrances, dust control additives, or a combination thereof.

### Claim 3 (depends on 1)

The method of claim 1, wherein the aminopolycarboxylic acid compound has an ethylenediamine or diethylenetriamine backbone.

### Claim 4 (depends on 1)

The method claim 1, wherein the aminopolycarboxylic acid compound is ethylenediaminetetraacetic acid or the salt thereof, diethylenetriaminepentaacetic acid or the salt thereof, N-hydroxyethylethylenediaminetriacetic acid or the salt thereof, or a mixture of two or more thereof.

### Claim 5 (depends on 1)

The method of claim 1, wherein the odor inhibitor comprises 500 to 15000 parts per million (ppm) of the contents of the container.

### Claim 6 (depends on 1)

The method of claim 1 wherein the carrier is wood chips, wood shavings, straw, diatomaceous earth, zeolites, bentonite clay, paper byproducts, pine pellets, ground corn cob or pelletized saw dust.

### Claim 7 (depends on 1)

The method of claim 1, wherein the polyprotic acid compound comprises citric acid, citrate, maleic, succinic, malonic, aspartic, the salt form of any of these acids, or a combination thereof.

### Claim 8

An odor control system comprising: a carrier material and an odor inhibitor, the odor inhibitor comprising an aminopolycarboxylic acid compound and a polyprotic acid compound, wherein at least one of the aminopolycarboxylic acid compound or the polyprotic acid compound is the salt form of the acid.

### Claim 9 (depends on 8)

The system of claim 8, wherein the aminopolycarboxylic acid compound has an ethylenediamine or diethylenetriamine backbone.

### Claim 10 (depends on 8)

The system claim 8, wherein the aminopolycarboxylic acid compound is ethylenediaminetetraacetic acid or the salt thereof, diethylenetriaminepentaacetic acid or the salt thereof, N-hydroxyethylethylenediaminetriacetic acid or the salt thereof, or a mixture of two or more thereof.

### Claim 11 (depends on 8)

The system of claim 8, wherein the odor inhibitor comprises 500 to 15000 parts per million (ppm) of the odor control system.

### Claim 12 (depends on 8)

The system of claim 8, wherein the polyprotic acid compound comprises citric acid, citrate, maleic, succinic, malonic, aspartic, the salt form of any of these acids, or a combination thereof.
