DURATION
- Preincubation period: 60 minutes at 37 °C
- After solidification the plates were incubated upside down for at least 48 hours at 37 °C in the dark.
DETERMINATION OF CYTOTOXICITY: Toxic effects were evidenced by a reduction in the number of spontaneous revertants or a clearing of the bacterial background lawn.
NUMBER OF REPLICATIONS: Two independent experiments performed in triplicate - Evaluation criteria:
- A test item is considered as a mutagen if a biologically relevant increase in the number of revertants exceeding the threshold of twice (strains TA 98, TA 100, and WP2 uvrA) or thrice (strains TA 1535 and TA 1537) the colony count of the corresponding solvent control is observed. A dose dependent increase is considered biologically relevant if the threshold is exceeded at more than one concentration. An increase exceeding the threshold at only one concentration is judged as biologically relevant if reproduced in an independent second experiment. A dose dependent increase in the number of revertant colonies below the threshold is regarded as an indication of a mutagenic potential if reproduced in an independent second experiment. However, whenever the colony counts remain within the historical range of negative and solvent controls such an increase is not considered biologically relevant.
- Statistics:
- No statistical evaluation of the data is required.

- Additional information on results:
- The plates incubated with the test item showed normal background growth up to 5000 µg/plate with and without S9 mix in both experiments. No relevant toxic effects, evident as a reduction in the number of revertants, occurred in the test groups with and without metabolic activation.
No substantial and reproducible increase in revertant colony numbers of any of the five tester strains was observed following treatment with FAT 40800/A at any dose level, neither in the presence nor absence of metabolic activation (S9 mix). A moderate but not strictly dose dependent increase of the number of revertant colonies was observed in strain TA 98 in the first experiment with metabolic activation. The colony count exceeded the historical range of negative and solvent controls somewhat at 33 - 333 µg/plate. At 333 µg/plate the threshold of twice the colony count of the corresponding solvent control was just exceeded (factor of 2.1 versus a threshold of 2.0) However, compared to the corresponding negative control a factor of only 1.5 was calculated. Furthermore this effect was not reproduced in the second assay. Therefore, this irreproducible increase was judged to be based upon fluctuations rather than indicating a possible mutagenic potential. There was also no reproducible tendency of higher mutation rates with increasing concentrations in the range below the generally acknowledged border of biological relevance. Appropriate reference mutagens were used as positive controls. They showed a distinct increase of induced revertant colonies. The positive control somewhat exceeded the historical range of positive controls in strains TA 1535 and TA 100 of the first experiment without metabolic activation. However, this effect indicates the sensitivity of the strains rather than compromising the validity of the assay. The positive control of strain TA 1535 in the second experiment with metabolic activation fell just short of the lower border of the historical range (61 colonies versus 68-511). Since the threshold of thrice the corresponding solvent control was clearly exceeded this minor deviation was also judged as biologically irrelevant.
Applicant's summary and conclusion
- Conclusions:
- FAT 40800/A did not show any mutagenic activity in any strain.
- Executive summary:
In a GLP-compliant Ames test, performed according to OECD guideline 471, 4 Salmonella typhimurium strains (TA 1535, TA 1537, TA 98, and TA 100) and one E. Coli strain (WP2 uvrA) were used to test the mutagenic potential of the test substance (33, 100, 333, 1000, 2500, and 5000 µg per plate), in two independent experiments (each in triplicate), both with and without metabolic activation. The test substance did not show any mutagenic activity in any strain and no toxic effects were observed. Therefore, the test substance is considered to be non-mutagenic in this Salmonella typhimurium and Escherichia coli reverse mutation assay.
