Note: : number of colonies obtained for the test substance/number of colonies obtained for the vehicle control. bPositive control: 2 μg/plate of sodium azide (TA100) and 0.2 µg/plate of 4-nitroquinoline-n-oxide (TA98) for test without S9 mix and 1 μg/plate of 2-aminoanthracene for test with S9. cVehicle control: solution of Tween 80 (20 µg/plate). dSD: standard deviation.
