Some new developments are also proposed such as a system based on the use of electrochemically active bacteria in combination with a microbial fuel cell [34], giving good responses over 60 days, or a biosensor developed for fast... 

Palmore also talked about examples of microbial systems. Derek Lovley s laboratory at University of Massachusetts, Amherst, is looking at doing electrochemistry in ocean or bay sediments. New organisms are being discovered through their research and the use of a microbial fuel cell in which carbohydrates are taken to carbon dioxide using Rhodoferax ferrireducens have been demonstrated. 

Reaction rates per unit area or volume of enzymatic systems are usually faster than those based on whole cell systems because of the higher loadings of desired enzymes per unit area or volume and no cellular membranes, which are often rate-limiting for substrate assimilation or product secretion (Figure 4.3). For example, it is believed that EFCs will become the next generation of environmentally friendly micropower sources but not microbial fuel cells...

THEORETICAL AND PRACTICAL CONSIDERATIONS FOR CULTURING Geobacter BIOFILMS IN MICROBIAL FUEL CELLS AND OTHER BIOELECTROCHEMICAL SYSTEMS... 

The successful application of microbial fuel cells (MFCs) and bioelectrochemical systems (BBSs) requires an understanding, and ultimately the optimization, of microbial activities associated with the bioelectrocatalytic conversion of chemical and electrical inputs. Researchers must always consider that MFC/BES reactors utilize living microorganisms to drive catalytic activity, and these microbes will respond to system changes in different ways than abiotic catalysts.

Figure 11.1 Schematic diagram of a benthic microbial fuel cell (BMFC). The anode was buried under the sediment, and the cathode floated underwater above the water-sediment interface. In this figure, electrons pass through aresistor. Instead of aresistor, a power management system can be used to increase potential and to operate a sensor.

A bioelectrochemical system (BES) is an electrochemical device used to convert electrical energy into chemical energy and vice versa. A BES consists of an anode and a cathode compartment, often separated by an ion-selective membrane. The anode is the site of the oxidation reaction which liberates electrons to the electrode and protons to the electrolyte the cathode is the site of the reduction reaction, which consumes the electrons to reduce a final electron acceptor. To maintain electroneutrality of the system, protons (or other cations) need to migrate to the cathode through the ion-selective membrane. Depending on the half-cell potentials of the electrodes, a BES can be operated either as a microbial fuel cell (MFC), in which electric energy is generated, or as a microbial...
