- Details on test system and experimental conditions:
- STANDARD PLATE
Test tubes containing 2 mL portions of soft agar which consists of 100 mL agar (0.6% agar + 0.6 % NaCl) and 10 mL amino acid solution (minimal amino acid solution for the determination of mutants: 0.5 mM histidine + 0.5 mM biotin) are kept in a water bath at 45°C, and the remaining components are added in the following order:
0.1 mL test solution
0.1 mL bacterial suspension
0.5 mL S-9 mix (in tests with metabolic activation) or 0.5 mL phosphate buffer (in tests without metabolic activation)
After mixing, the samples are poured onto Vogel-Bonner agar plates (minimal glucose agar plates) within approx. 30 seconds.
PREINCUBATION TEST
0.1 mL test solution, 0.1 mL bacterial suspension and 0.5 mL S-9 mix are incubated at 37°C for the duration of 20 minutes. Subsequently, 2 mL of soft agar is added and, after mixing, the samples are poured onto the agar plates within approx. 30 seconds.
BOTH TESTS
In each experiment 3 test plates per dose or per control were used. After incubation at 37°C for 48 hours in the dark, the bacterial colonies (his+ / trp+ revertants) are counted. The titer is determined only in the experiments with S-9 mix both without test substance (solvent only) and after adding the two highest amounts of substance. Sterility control was performed. - Evaluation criteria:
- A substance to be characterized as positive in the bacterial tests, has to fulfill the following requirements:
- doubling of the spontaneous mutation rate (control)
- dose-response relationship
- reproducibility of the results.
