Population dynamics of pseudomonads after iodination.
The population dynamics of pseudomonads grown under rich or low nutrient conditions were examined following iodination. Iodinated and untreated controls of Pseudomonas aeruginosa or Pseudomonas cepacia were resuspended in phosphate buffer and incubated at room temperature. Viable populations of iodine-treated cultures increased faster in phosphate-buffered water than uniodinated controls. Thus, bacteria in iodinated water systems may recover or multiply during storage and distribution after disinfection and may pose a significant health risk.
