J. Sawai et al., Ames assay with Salmonella typhimurium TA102 for mutagenicity and antimutagenicity of metallic oxide powders having antibacterial activities, WORLD J MIC, 14(5), 1998, pp. 773-775
Metallic oxide powders (magnesium oxide, calcium oxide and zinc oxide) havi
ng antibacterial activity were examined for their mutagenicity and antimuta
genicity by the Ames test with Salmonella typhimurium TA 102. These powders
were not mutagenic to the tester strain and reduced the mutagenicity of me
thylglyoxal.
