利用细菌细胞实现了纳米钯的生物制造。高活性Pd催化剂（Bio-Pd）由E.大肠杆菌突变体在燃料电池中提供功率输出。与商业Pd电极（~0.099 W）相比，通过来自大肠杆菌的生物Pd催化剂电极实现了高达~115%的最大发电量。生物贵金属（Bio-PM）催化剂直接由E。将大肠杆菌制成燃料电池电极，最大发电功率约为0.06W。
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 ~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 (~0.099 W). A bio-precious-metals (Bio-PM) catalyst made directly from an industrial reprocessing solution by the E. coli was also made into fuel cell electrodes and ~0.06W of maximum power generation was observed.
