title: Genetic toxicology evaluation of commercial beers. II. Mutagenic activity of commercial beer products in Salmonella typhimurium strains TA98, TA100 and TA102.
abstract: 5 concentrated extracts of commercial beers were prepared using XAD-2 resin. The residues were subjected to evaluation for mutagenic activity in Salmonella typhimurium strains TA98, TA100 and TA102. The tests were conducted using preincubation protocols including provisions for S9 metabolic activation. Although the extracts did produce moderate toxicity to the Salmonella organisms used in the assays, none of the residues were found to induce mutation up to their maximum testable concentrations.
