Biological Recovery of Platinum Complexes from Diluted Aqueous Streams by Axenic Cultures

The effect of the addition of Pt(II)Cl42- on the membrane integrity of different bacterial cells during platinum recovery as a function of time.

Four different bacterial cultures were studied; Shewanella oneidensis MR-1, Cupriavidus metallidurans CH34, Bacillus toyonensis and Pseudomonas stutzeri. The recovery experiment was started at t0 by the addition of 100 mg L-1 Pt and H2-gas as electron donor. The pH was initially set at pH 2.0.
