Inside Cover: Biogenic Iron Sulfide Nanoparticles to Enable Extracellular Electron Uptake in Sulfate‐Reducing Bacteria (Angew. Chem. Int. Ed. 15/2020)

Iron sulfide nanoparticles (FeS NPs) mediate bacterial extracellular electron uptake from solid electron donors. In their Research Article on page 5995, A. Okamoto et al. demonstrate that self-synthesized FeS NPs on the cell surface enable sulfate-reducing bacteria to extract electrons from electrodes, coupled with metabolic activation. The result sheds light on the biogeochemical cycling of carbon, iron, and sulfur and the anaerobic corrosion mechanism.
