Results are presented as the percentage of inhibition of AFB₁ mutation and are representative of three repetitions.
Values with different letters within a column are significantly different (). Spontaneous revertants/plate were 31 ± 3 and 117 ± 6 and AFB₁ control (500 ng) were 625 ± 26 and 958 ± 27 revertants/plate for TA98 and TA100, respectively.
