- METHOD OF APPLICATION: in agar (plate incorporation) at multiple dose levels, in triplicate, both with and without the addition of a rat liver homogenate metabolising system (10% liver S9 in standard co-factors).
The assay was performed by mixing 0.1 ml of bacterial culture (TAI00 or WP2uvrA-), 0.1 ml of the substance formulation, 0.5 ml of S9-mix or phosphate buffer and 2 ml of molten, trace histidine or tryptophan supplemented, top agar and overlaying onto sterile plates of Vogel-Bonner Minimal agar (30 ml/plate). In total ten concentrations of the test material and a vehicle control (acetone) were tested. In addition, 0.1 ml of the maximum concentration of the test material and 2 ml of molten, trace histidine or tryptophan supplemented, top agar were overlaid onto a sterile Nutrient agar plate in order to assess the sterility of the test material. After approximately 48 hours incubation at 37°C the plates were assessed for numbers of revertant colonies and examined for effects on the growth of the bacterial background lawn.

DETERMINATION OF CYTOTOXICITY
- Method: N/A
OTHER EXAMINATIONS:
N/A
OTHER:
Prior to the master strains being used, characterisation checks were carried out to confirm the amino-acid requirement, presence of rfa, R factors, uvrB or uvrA mutation and the spontaneous reversion rate.
In order to select appropriate dose levels for use in the main test, a preliminary assay was carried out to determine the toxicity of the test material. - Evaluation criteria:
- There are several criteria for determining a positive result. Any, one, or all of the following can be used to determine the overall result of the study:
1 . A dose-related increase in mutant frequency over the dose range tested (De Serres and Shelby, 1979).
2. A reproducible increase at one or more concentrations.
3. Biological relevance against in-house historical control ranges.
4. Statistical analysis of data as determined by UKEMS (Mahon et al, 1989).
5. Fold increase greater than two times the concurrent solvent control for any tester strain (especially if accompanied by an out-of-historical range response (Cariello and Piegorsch, 1996)).
A test item will be considered non-mutagenic (negative) in the test system if the above criteria are not met.
Although most experiments will give clear positive or negative results, in some instances the data generated will prohibit making a definite judgment about test item activity. Results of this type will be reported as equivocal. - Statistics:

Any other information on results incl. tables
The maximum dose level of the test item in the first experiment was selected as the maximum recommended dose level of 5000 ug/plate. There was no visible reduction in the growth of the bacterial background lawn at any dose level, either in the presence or absence of metabolic activation, in the first mutation test and consequently the same maximum dose level was used in the second mutation test. Similarly, there was no visible reduction in the growth of the bacterial background lawn at any dose level, either in the presence or absence of metabolic activation, in the second mutation test. A test item film (cream-colored in appearance) was observed at 5000 ug/plate , this observation did not prevent the scoring of revertant colonies. There were no significant increases in the frequency of revertant colonies recorded for any of the bacterial strains, with any dose of the test item, either with or without metabolic activation in Experiment 1 . Similarly, no significant increases in the frequency of revertant colonies were recorded for any of the bacterial strains, with any dose of the test item, either with or without metabolic activation in Experiment 2. All of the positive control chemicals used in the test induced marked increases in the frequency of revertant colonies thus confirming the activity of the S9-mix and the sensitivity of the bacterial strains.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
The test item was considered to be non-mutagenic under the conditions of this test. - Executive summary:
Introduction
The test method was designed to be compatible with the guidelines for bacterial mutagenicity testing published by the major Japanese Regulatory Authorities including METI, MHLW and MAFF, the OECD Guidelines for Testing of Chemicals No. 471 "Bacterial Reverse Mutation Test", Method B13/14 of Commission Regulation (EC) number 440/2008 of 30 May 2008 and the USA, EPA OCSPP harmonized guideline 870.5100 - Bacterial Reverse Mutation Test.
Method
Salmonella typhimurium strains TA1535, TA1537, TA98 an d TA100 and Escherichia coli strain WP2uvrA were treated with the test item using the Ames plate incorporation method at up to eight dose levels, in triplicate, both with and without the addition of a rat liver homogenate metabolizing system (10% liver S9 in standard co-factors). The dose range for Experiment 1 was predetermined and was 1.5 to 5000 ug/plate. The experiment was repeated on a separate day using fresh cultures of the bacterial strains and fresh test item formulations. The dose range was amended, following the results of Experiment 1 , and was 50 to 5000 ug/plate.
Results
The vehicle (dimethyl sulphoxide) control plates gave counts of revertant colonies within the normal range. All of the positive control chemicals used in the test induced marked increases in the frequency of revertant colonies, both with or without metabolic activation. Thus, the sensitivity of the assay and the efficacy of the S9-mix were validated. The maximum dose level of the test item in the first experiment was selected as the maximum recommended dose level of 5000 ug/plate . There was no visible reduction in the growth of the bacterial background lawn at any dose level, either in the presence or absence of metabolic activation, in the first mutation test and consequently the same maximum dose level was used in the second mutation test. Similarly, there was no visible reduction in the growth of the bacterial background lawn at any dose level, either in the presence or absence of metabolic activation, in the second mutation test. A test item film (cream-colored in appearance) was observed at 5000 ug/plate, this observation did not prevent the scoring of revertant colonies.
There were no significant increases in the frequency of revertant colonies recorded for any of the bacterial strains, with any dose of the test item, either with or without metabolic activation in Experiment 1. Similarly, no significant increases in the frequency of revertant colonies were recorded for any of the bacterial strains, with any dose of the test item, either with or without metabolic activation in Experiment 2. The test item was considered to be non-mutagenic under the conditions of this test.
