[Study on mutagenicity of Toxoflavin from Pseudomonas farinofermentans].

Fermented corn flour containing toxoflavin and bongkretic acid produced by P. farinofermentans can cause acute food poisoning, but study on mutagenicity of toxoflavin has not been reported. We studied the mutagenicity of toxoflavin by Tradescantia Paludosa and animal micronucleus tests. The results showed that toxoflavin possesses distinct mutagenic action in both plant and animal cells. Mutagenic action of toxoflavin in cells may have important bearing on food hygiene examination.
