Extracellular electron uptake in the micro-bioelectrochemical cell. a Schematic drawing of a single, four-chamber micro-bioelectrochemical (µ-BEC) with b microbial cells attached to the indium tin oxide (ITO) working electrode (WE). The reference (RE) and counter (CE) electrodes are silver and platinum wires, respectively (not drawn to scale). c Confocal micrograph of Rhodopseudomonas palustris TIE-1 biofilms attached to the WE under poised conditions using LIVE/DEAD® staining. Green cells are viable. Scale bars are 10 µm. d Current densities for TIE-1 wild-type (WT) (black) in the µ-BEC under illuminated and dark conditions (shaded regions) compared to a ‘No cell control’ reactor (red). Data shown are representative of three experiments. Source data are provided as a Source Data File
