TLDR
It is shown that the γ-proteobacterium Shewanella oneidensis can reduce tetrachloroaurate (III) ions to produce discrete extracellular spherical gold nanocrystallites, which were homogeneously shaped with multiple size distributions and produced under ambient conditions at high yield, 88% theoretical maximum.About:
