Nanowires produced by the oxygenic phototrophic cyanobacterium Synechocystis PCC6803 and the thermophilic, fermentative bacterium Pelotomaculum thermopropionicum reveal that electrically conductive appendages are not exclusive to dissimilatory metal-reducing bacteria and may, in fact, represent a common bacterial strategy for efficient electron transfer and energy distribution.
Electricity generation using an air-cathode single chamber microbial fuel cell in the presence and absence of a proton exchange membrane.
An analysis based on available anode surface area and maximum bacterial growth rates suggests that mediatorless MFCs may have an upper order-of-magnitude limit in power density of 10(3) mW/m2.

Findings show that brush anodes that have high surface areas and a porous structure can produce high power densities, and therefore have qualities that make them ideal for scaling up MFC systems.
Power generation in fed-batch microbial fuel cells as a function of ionic strength, temperature, and reactor configuration.
It is demonstrated that power densities can be increased to over 1 W/m2 by changing the operating conditions or electrode spacing, which should lead to further improvements in power generation and energy recovery in single-chamber, air-cathode MFCs.
