Salmonella typhimuriurn TA100, TA98, TA1535, TA1537 and TA1538 were obtained from Professor B.N. Ames, University of California, U.S.A.
Escherichia coli WP2 uvrA was provided by Dr. T. Kada, National Institute of Genetics, Mishima, Japan.
Cultures of each strain were prepared by incubating an aliquot of parent stock culture in nutrient broth at 37°C for 18 hours.
After mixing 0.1 ml of test material solution, 0.5 ml of phosphate buffer or S-9 mix, 0.1 ml of culture of tester strain, and 2 ml of top agar in a test tube, the mixture was poured on minimal agar plate. The plates were incubated at 37°C for 2 days and scored, for revertants.

Applicant's summary and conclusion
- Conclusions:
- Under the study conditions, the test substance was found to be mutagenic in most Salmonella strains in bacterial reverse mutation assay.
- Executive summary:
A bacterial reverse mutation assay (Ames) was carried out, to evaluate the test substance for the mutagenic potential in a microbial assay with and without the addition of mammalian metabolic activation preparation. The test was carried out in concentrations of 10, 50, 100, 500, 1000 and 5000 µg/plate in strains of Salmonella typhimurium TA100, TA98, TA1535, TA1537 and TA1538 and Escherichia coli WP2 uvrA. Cultures of each strain were prepared by incubating an aliquot of parent stock culture in nutrient broth at 37°C for 18 hours. After mixing 0.1 ml of test material solution, 0.5 ml of phosphate buffer or S-9 mix, 0.1 ml of culture of tester strain, and 2 ml of top agar in a test tube, the mixture was poured on minimal agar plate. The plates were incubated at 37°C for 2 days and scored, for revertants.
Significant differences were observed in the number of mutant colonies between the test compound dosages and the control with Salmonella typhimurium TA100, TA98, TA1535, TA1537 and TA1538. No increases in mutation frequencies were observed in Escherichia coli WP2 uvrA.
