Abstract
This invention relates to the preparation of new, naturally produced chelating agents as well as to the method and resulting chelates of desorbing cultures in a bioavailable form involving Pseudomonas species or other microorganisms. A preferred microorganism is Pseudomonas aeruginosa which forms multiple chelates with thorium in the range of molecular weight 100-1,000 and also forms chelates with uranium of molecular weight in the area of 100-1,000 and 1,000-2,000.
Claims4
A mixture of chelating agents that complex with the toxic metal thorium, which agents are produced by the microorganism Pseudomonas aeroginosa PAO-1 (ATCC 15692) grown in a conventional growth medium containing thorium as a challenge metal.
A mixture of chelating agents that complex with the toxic metal uranium, which agents are produced by the microorganism Pseudomonas aeroginosa PAO-1 (ATCC 15692) grown in a conventional growth medium containing uranium as a challenge metal.
