title: Recombinogenicity and mutagenicity of saccharin in Saccharomyces cerevisiae.
abstract: Diploid yeast grown in the presence of a commercial lot of saccharin exhibited reproducible, dose-dependent increases in intergenic and intragenic recombination, and mutation. Cells grew to nearly the same titer in media without saccharin and containing 2 or 20 mg saccharin/ml, although cell viability was somewhat reduced in saccharin-containing media. At the high test dose of 100 mg/ml, titers and cell viability were more markedly lowered. Differences between this study and previous (negative) tests of saccharin in yeast are described.
