Structures of live biofilms formed on graphite plates under aerobic (a) and electricity-generating (b, c) conditions by GFP-expressing S. oneidensis MR-1 in the presence of medium flow. For current generation, potentials of graphite-plate electrodes were poised at 0 V (b) and + 0.4 V (c) vs. Ag/AgCl reference electrodes. Top images are XZ projections, while bottom images are XY projections
