- METHOD OF APPLICATION: in agar
The strains of S. typhimurium were obtained from the National Collection of Type Cultures,London, England.
The strain of E. coli was obtained from the National Collections of Industrial and MarineBacteria, Aberdeen, Scotland.
Aliquots of 0.1 mL of the test substance solutions, positive control or negative control were placed in glass vessels. The negative control was the chosen vehicle, DMSO. S9 mix (0.5 mL) or 0.1 M pH 7.4 phosphate buffer (0.5 mL) was added, followed by 0.1 mL of a 10-hour bacterial culture and 2 mL of agar containing histidine (0.05 mM), biotin (0.05 mM) and tryptophan (0.05 mM). The mixture was thoroughly shaken and overlaid onto previously prepared Petri dishes containing 25 mL minimal agar. Each Petri dish was individually labelled with a unique code, identifying the contents of the dish. Three Petri dishes were used for each treatment. Plates were also prepared without the addition of bacteria in order to assess the sterility of the test substance, S9 mix and sodium phosphate buffer. All plates were incubated at approximately 37C for ca 72 hours. After this period, the appearance of the background bacterial lawn was examined and revertant colonies counted using an automated colony counter (Perceptive Instruments Sorcerer).
As a clear negative response was obtained in the first test, a variation to the test procedure was used for the second test. The variation used was the pre-incubation assay in which the tubes, which contained mixtures of bacteria, buffer or S9 mix and test dilution, were incubated at 37°C for 30 minutes with shaking before the addition of the agar overlay. The maximum concentration chosen was again 5000 µg/plate, but only five concentrations were used. - Evaluation criteria:
- For a test to be considered valid, the mean of the vehicle control revertant colony numbers for each strain should lie within or close to the 99% confidence limits of the current historical control range of the laboratory unless otherwise justified by the Study Director. The historical range is maintained as a rolling record over a maximum of five years. Also, the positive control compounds must induce an increase in mean revertant colony numbers of at least twice (three times in the case of strains TA1535 and TA1537) the concurrent vehicle controls. Mean viable cell counts in the 10-hour bacterial cultures must be at least 109/mL.
- Statistics:
- The mean number and standard deviation of revertant colonies were calculated for all groups. The “fold-increases” relative to the vehicle controls were calculated in order to compare the means for all treatment groups with those obtained for the vehicle control groups.

Any other information on results incl. tables
The concurrent positive controls demonstrated the sensitivity of the assay and the metabolising activity of the liver preparations. The mean revertant colony counts for the vehicle controls were within or close to the 99% confidence limits of the current historical control range of the laboratory.
Applicant's summary and conclusion
- Conclusions:
- It is concluded that Hexahydrophthalic anhydride (HHPA) showed no evidence of mutagenic activity in this bacterial system under the test conditions employed.
- Executive summary:
Gene mutation has been investigated in bacteria using strains of Salmonella typhimurium and Escherichia coli, in accordance with OECD/EU test methods. Five tester strains TA1535, TA1537, TA98, TA100 and WP2uvrA were used and experiments were performed both in the absence and presence of metabolic activation, using liver S9 fraction from rats pre-treated with phenobarbital and 5,6-benzoflavone. The substance, hexahydrophthalic anhydride (HHPA), did not induce reverse mutation in the tester strains, neither in the absence nor presence of S9 metabolism.
