- Observations:
In the dose-finding test, growth inhibition was observed at 313 micrograms/plate and more in S. typhimurium TA98 and TA1537 without metabolic activation, at 1250 micrograms/plate and more in S. typhimurium TA100, TA1535 and E. coli WP2uvrA without metabolic activation, and at 1250 micrograms/plate and more in all strains with metabolic activation. Moreover, an increase in the number of revertant colonies more than twice as many as that of negative control was observed in S.typhimurium TA98 without metabolic activation and in E. coli WP2uvrA with metabolic activation. Precipitate was not observed on the plates treated with test substance, with or without metabolic activation.
