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

Fig 3

Transmission electron microscopy (TEM) images of thin sections of the five different bacterial species, loaded with platinum particles.

The precipitation of platinum was induced by the presence of hydrogen gas. No Pt particles were observed during the recovery of cisplatin by Bacillus toyonensis and Pseudomonas stutzeri, while Geobacter metallireducens was not studied for this complex.
