Mutagenicity and co-mutagenicity of catechol on Salmonella.
Catechol was not mutagenic for Salmonella typhimurium TA98, TA100 or TA1537 in the presence or absence of S9 mix. At the lower level of S9 in the Ames method, the mutagenic activity of benzo[a]pyrene decreased with the increased addition of catechol. When catechol was added to the pre-incubation mixture at a higher concentration than in the conventional Ames method, the mutagenic activity of benzo[a]pyrene increased with the increased addition of catechol. Catechol is believed to be a co-mutagen for benzo[a]pyrene in the presence of a sufficient amount of S9 in the incubation mixture.
