Abstract

Room temperature bioreduction of gold ions was attained within relatively short reaction time (3-120 min) using a metal ion-reducing bacterium <i>Shewanella oneidensis</i>. The soluble gold ions were reduced to gold nanoparticles when formate was provided as an electron donor. The biogenic precipitates in the <i>S. oneidensis</i> cells were gold nanocrystals of approximately 10 nm in size and homogeneously deposited on the bacteria surface. Both the generated particle amount per unit bacterial cell and particles diameters were varied by initial formate concentration and reaction time. In this experiment, the highly dispersed gold nanoparticles could be controlled from 3.8 to 14.2 nm precipitating on the bacteria surface.
