Factors Modulating Mutagenicity in Microbial Tests

  • Conference paper
Short-Term Test Systems for Detecting Carcinogens

Summary

The preincubation of test compound, bacterial tester strain, and S-9 mix or buffer before pouring a minimal-glucose agar plate enhanced the sensitivity of mutation test and increased the spectrum of mutagens detected. Addition of NADH and ATP in S-9 mix enhanced the mutagenicity of some compounds. Addition of norharman in the preincubation mixture made it possible to detect a marginal or weak mutagenicity of certain types of mutagens. Addition of riboflavin revealed the mutagenicity of azo compounds. Glycosidase was required to detect the mutagenicity of glycosides or natural products.
