Induced formation of chelating agents by Pseudomonas aeruginosa grown in presence of thorium and uranium

The ability of the bacteria pseudomonas aeruginosa to elaborate sequestering agents in medium containing thorium or uranium salts was tested. Addition of 10, 100, and 1000 ppm of U or th to culture medium increased the lag period of the organisms as the concentration of the metal increased. U had a...

Description
Summary:The ability of the bacteria pseudomonas aeruginosa to elaborate sequestering agents in medium containing thorium or uranium salts was tested. Addition of 10, 100, and 1000 ppm of U or th to culture medium increased the lag period of the organisms as the concentration of the metal increased. U had a stronger inhibitory effect on the organism than th. Analyses of the culture medium have shown that the microorganisms produced several new chelating agents for th and U.
