    FIG. 1.

    Acetate disappearance (•), electron recovery predicted on the basis of acetate disappearance (○), electron recovery on the basis of integrated amperage (solid line), and current production (inset) for a representative microbial fuel cell containing G. fermentans attached to a graphite electrode. The anode was connected to a graphite cathode (in aerated water) via a 500-Ω resistor.

    FIG. 3.

    Fe(III)-oxide reduction by G. sulfurreducens resting cell suspensions incubated with supernatants from G. fermentans fuel cells. Effects of supernatants from two 7-day-old fuel cells (▵, ▴) and two 35-day-old fuel cells (□, ▪) are shown, with the effects of 25 μM (♦) and 50 μM (⋄) AQDS shown for comparison.

    FIG. 4.

    Overvoltages for anodes and cathodes in a representative G. fermentans fuel cell over a range of current densities. Characteristics were measured 7 days after medium replacement (▵, ▴), in the same fuel cell 35 days after medium replacement (○, •), and with 50 μM AQDS addition 1 day later (□, ▪). Values closer to zero as the rate of current flow increases indicate improvements in operating cell voltage.
