Bioreductive deposition of platinum nanoparticles on the bacterium Shewanella algae.

An environmentally friendly method using the metal ion-reducing bacterium Shewanella algae was proposed to deposit platinum nanoparticles. Resting cells of S. algae were able to reduce aqueous PtCl(6)(2-) ions into elemental platinum at room temperature and neutral pH within 60min when lactate was provided as the electron donor. Biogenic platinum nanoparticles of about 5nm were located in the periplasm--a preferable, cell surface location for easy recovery of biogenic nanoparticles.
