A Role for Microbial Palladium Nanoparticles in Extracellular Electron Transfer

Precious bacterium: Biologically produced palladium nanoparticles bound to a cell membrane participated in electron-transport pathways as well as electrocatalysis on an electrode surface (see picture). Periplasmic hydrogenases (FeFe) and cytochromes (Cyt) may be involved in the processes.
