- Details on test system and experimental conditions:
- Assay without metabolic activation:
For each of the strains, 100 μL of the bacterial suspension (1-5 x 109 bacteria/mL) and 100 μL of the
test substance are mixed with 2.0 mL of overlay agar and poured over the surface of a minimal agar
plate (90 mm in diameter) (n = 3). The overlay agar is allowed to solidify before incubation.
Plates are incubated at 37° C over a 48 hour period. The number of revertant colonies per plate is
counted.
Moreover the following controls are carried out :
- negative controls
. absolute negative control (spontaneous reversion rate),
. positive control solvent.
- test substance solvent if necessary.
- positive control
Assay with metabolic activation:
Two tests can be performed using
• either a standard plate incorporation method where the protocol is similar to that described above, except that just before pouring the mixture onto the plates, 500 μL of S9-mix fraction is quickly mixed,
• or the pre-incubation assay where the test substance is preincubated with the test strain, and 500 μL of S9-mix fraction for 1 hour at 37° C
prior to mixing with the overlay agar and pouring onto the surface of the minimal agar plate. Tubes should be aerated during preincubation by using a shaker. This method is known to increase the detection sensitivity of a number of promutagens like alkaloïds, aliphatic N-Nitroso compounds
If the first assay is positive, the second one is performed in the same manner.
If the first assay is negative, the pre-incubation test is performed for the second assay. - Evaluation criteria:
- After a 48 hour incubation period at 37° C, revertant colonies per plate are counted.
Data are presented as the number of revertant colonies (mean ± standard deviation) per plate.
The following ratio is calculated :
Number of revertant colonies in the presence of the product
R = _______________________________________________________________________
Number of revertant colonies in the absence of the product

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
There is no significant difference between the number of spontaneous reversions, the number of reversions obtained in the positive controls
(without and with metabolic activation), and the mean of corresponding experimental historic values obtained in the laboratory.
There is no evidence of any increase in the number of revertant colonies in the presence of the test substance (1 500 μg - 450 μg 150 μg - 45 μg - 15 μg) without and with metabolic activation.
Results were confirmed in a second independent experiment.
In summary:
At these doses the test substance, PROTEOL APL (LEMI code : DTT221203) supplied by SEPPIC does not induce any mutagenic change in Salmonella
typhimurium TA 1535, TA 1537, TA 98, TA 100 and Escherichia coli WP2(uvrA-) (pKM 101), without or with metabolic activation, according to the
guideline OECD n° 471 and to the method B13/B14 of the directive CE/2000/32. - Executive summary:
Test substance: PROTEOL APL - Batch n° 335JG
Test procedure: Reverse mutation assay on «Salmonella typhimurium his-» and «Escherichia coli» WP2(uvrA-) (pKM 101) strains according to the OECD guideline n° 471 (LEMI operating procedure MB08/45).
Test result : The test substance does not induce reverse mutation on four Salmonella typhimurium strains and one Escherichia coli WP2(uvrA-) (pKM 101) strain, according to the OECD guideline n° 471 and to the method B13/B14 of the directive CE/2000/32.
