Confocal scanning laser microscopy images of <i>Geobacter sulfurreducens</i> grown with different electron acceptors.
<p>Confocal scanning laser microscopy images of current harvesting and fumarate control biofilms of wild type <i>G. sulfurreducens.</i> Metabolically active (green) and inactive (red) cells where differentiated with a LIVE/DEAD kit based on the permeability of the cell membrane. A. 3-D projection, top view, fumarate control biofilm; B. slices through biofilm parallel to electrode large panel and perpendicular to electrode top and side panel, fumarate control biofilm; C. 3-D projection, top view, current harvesting biofilm; D. slices through biofilm parallel to electrode large panel and perpendicular to electrode top and side panel, current harvesting biofilm.</p

Maximal current production of fuel cells inoculated with wild-type cells of <i>G. sulfurreducens</i> or strains with the designated genes deleted or the deleted genes complemented via expression of the designated gene on a plasmid.
<p>Values are the average±the standard deviation of triplicates.</p
Gene transcripts whose expression (arithmetic) was significantly increased when <i>G. sulfurreducens</i> was grown within a current-harvesting 10 mA potentiostat biofilm versus a fumarate control biofilm.
<p>Limma Analysis with a maximum p value of 0.001 was used for statistical analysis.</p
