Method
Species / strain
- Species / strain / cell type:
- S. typhimurium TA 1535, TA 1537, TA 98, TA 100 and TA 102
- Additional strain / cell type characteristics:
- other: Defective lipopolysaccharide barrier on the cell wall (rfa).
- Metabolic activation:
- with and without
- Metabolic activation system:
- The cofactor supplemented post-mitochondrial fraction (S9) was employed as the metabolic activation system
- Test concentrations with justification for top dose:
- Eight concentrations of test item, formulated in analytical grade water, corresponding to proposed test doses viz. 5000, 4000, 3000, 2000, 1000, 500, 250 and 125 μg/plate of the test item, were tested for visible precipitation.
During the test, no precipitation was observed at concentration of 5000 μg/plate to125 μg/plate. Hence, 5000 μg/plate with no precipitation was selected as the highest test dose for the preliminary cytotoxicity test.
Results of preliminary cytotoxicity test, evaluated from appearance of the bacterial background lawn and frequencies of histidine revertant colonies, there was no cytotoxicity observed for bacterial background lawn and histidine revertant colonies at the concentrations from 5000 and 125 μg/plate, both in presence and absence of metabolic activation system.
Therefore, 5000 g/plate was selected as the highest test dose for the definitive study, both in presence and absence of metabolic activation system. - Vehicle / solvent:

- MEDIUM
The bacterial strains were cultured in Oxoid Nutrient Broth No. 2. Minimal glucose agar contained agar, Vogel-Bonner minimal medium E and 2% glucose. The top agar contained 0.6% agar, 0.5% NaCl and 0.05 mM solution of L-histidine with D-biotin (Maron and Ames, 1983).
METABOLIC ACTIVATION
The cofactor supplemented post-mitochondrial fraction (S9) was employed as the metabolic activation system.

Applicant's summary and conclusion
- Conclusions:
- Salmonella typhimurium, Reverse Mutation Assay of Ammonium propionate (CAS: 17496-08-1) in aqueous solution (50-55%) was carried out in accordance with the Organisation for Economic Co-operation and Development (OECD) Guidelines for Testing of Chemicals (Guideline No. 471, Section 4: Health Effects) on conduct “Bacterial Reverse Mutation Test” adopted by the council on 21st July 1997.
Under the conditions described for this study, it is concluded that Ammonium propionate (CAS: 17496-08-1) in aqueous solution (50-55%) in non-mutagenic in Salmonella typhimurium, Reverse Mutation Assay (AMES Test)
