Ames mutagenicity tests on purified 3-nitropropionic acid.
Abstract
3- Nitropropionic acid is a toxic compound produced by several moulds involved in food fermentation or spoilage. An impure commercial sample of this compound was previously reported as being mutagenic to Salmonella typhimurium strains TA1535 and TA100. In the present study, a sample from the same lot of 3- nitropropionic acid was mutagenic in strain TA100 without metabolic activation, but this activity was diminished after recrystallization. This sample was not mutagenic in strain TA98, before or after recrystallization. A new, purer commercial sample was non-mutagenic in strains TA98, TA100 and TA1538, with or without metabolic activation. Therefore the mutagenicity reported to be due to 3- nitropropionic acid was considered to be due to the impurity(ies).
