Abstract

Summary

Tests with 140 strains representing and in a defined medium supplemented with 009M dimethylamine (DMA) and (MM potassium nitrate showed that at least 89% of the 136 strains able to reduce nitrates produced up to 9mM dimethylnitrosamine (DMN) in 70 h at 37°C. Four nitratase-negative strains produced DMN from DMA in the presence of sodium nitrate. Prolonged incubation was the most important factor in determining DMN production. Stasis and persistent infection in the urinary tract, by simulating prolonged incubation of a culture, may be of importance in determining whether the potential carcinogen, DMN, could be produced by bacterial action on DMA and nitrate in urine.
