The abundance and significance of a class of large, transparent organic particles in the ocean
Polysaccharide-specific staining techniques reveal the existence and high abundance of a class of large, discrete, transparent particles in seawater and diatom cultures formed from dissolved exopolymers exuded by phytoplankton and bacteria, suggesting that they may alter the distributions and microenvironments of marine microbes in nature.

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. Expand

This Progress article explores the underlying reasons for exocellular electron transfer, including cellular respiration and possible cell–cell communication, to understand bacterial versatility in mechanisms used for current generation. Expand
Electrically conductive bacterial nanowires produced by Shewanella oneidensis strain MR-1 and other microorganisms.
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. Expand
Electricity-producing bacterial communities in microbial fuel cells.
The microbial communities found in MFCs, collectively defined as a community of "exoelectrogens", and the prospects for this emerging bioenergy technology are reviewed. Expand
Increased performance of single-chamber microbial fuel cells using an improved cathode structure
Maximum power densities by air-driven microbial fuel cells (MFCs) are considerably influenced by cathode performance. We show here that application of successive polytetrafluoroethylene (PTFE) layersExpand
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. Expand
Electrochemically assisted microbial production of hydrogen from acetate.
By augmenting the electrochemical potential achieved by bacteria in this MFC with an additional voltage of 250 mV or more, it was possible to produce hydrogen at the cathode directly from the oxidized organic matter. Expand
