    Bio-manufacturing of nano-scale palladium was achieved using bacterial cells. Highly active Pd-catalyst (Bio-Pd) produced by an E. coli mutant gave power output in a fuel cell. Up to similar to 115% of the maximum power generation was achieved by electrodes of Bio-Pd catalysts from Escherichia coli, compared to that from a commercial-Pd electrode (similar to 0.099 W). A bio-preciousmetals (Bio-PM) catalyst made directly front an industrial reprocessing solution by the E coli was also made into fuel cell electrodes and similar to 0.06W of maximum power generation was observed.
