Photoferrotrophs Produce a PioAB Electron Conduit for Extracellular Electron Uptake (image) Washington University in St. Louis Share Print E-Mail Caption Photoferrotrophy is a form of anoxygenic photosynthesis whereby bacteria utilize soluble or insoluble forms of ferrous iron as an electron donor to fix carbon dioxide using light energy. New research from the laboratory of Arpita Bose, assistant professor of biology in Arts & Sciences at Washington University in St. Louis, shows how one of these kinds of bacteria builds a special electron conduit to harvest electricity directly from the source.
