Salmonella typhimurium TA98 and TA100 strains (CFUs) exposed to the direct mutagens 4-nitroquinoline-1-oxide (4-NO) and sodium azide (SAZ) without metabolic activation (S9−). Salmonella typhimurium TA98 and TA100 (CFUs) strains exposed to the indirect mutagen aflatoxin B1 (AFB1) with metabolic activation (S9+, microsomal activation system: microsomal fraction of rat liver homogenate). Values are expressed as the mean ± SEM of the experiment performed in triplicate. when the means of the treated groups are compared with the 4-NO (TA98/without S9), SAZ (TA100/without S9), and AFB1 (TA98 and TA100 with S9) groups. —: unvalued.
