ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY AS A POWERFUL ANALYTICAL TOOL FOR THE STUDY OF MICROBIAL ELECTROCHEMICAL CELLS... 

Microbial electrochemical cells (MXCs) represent a new class of technologies, within the realms of wastewater treatment, bioremediation, and bioenergy generation [1-3], MXCs rely on the unique capability of certain bacteria to use electrodes in their metabolism, either as electron acceptors or as electron donors [4-6], MXCs represent one of the most challenging types of bioreactors and electrochemical reactors to scale... 

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... 

Biofuel cells — also referred to as biochemical, or bio-electrochemical fuel cells, exploit biocatalysts for the direct conversion of chemical energy to electrical energy. Based on the nature of the biocatalyst, biofuel cells are generally classified as enzymatic fuel cells and microbial fuel cells [i]. Enzymatic fuel cells use purified enzymes to catalyze the oxidation of substrates at the - anode and... 

In microbial fuel cells living microorganisms serve as bio catalysts for the conversion of chemical energy to electricity. Since the majority of microorganisms are electrochemically inactive some early microbial fuel cells required the use of artificial electron-shuttling com-... 

An innovative electrochemical lab on a chip system has been developed by Popovtzer et al. (2006) for the measurement of microbial responses to toxic chemicals. The miniaturized device was designed in two parts to enable multiple measurements a disposable silicon chip containing an array of nano-volume electrochemical cells that house the biological material, and a reusable unit that includes a multiplexer and a potentiostat connected to a pocket PC for sensing and data analysis.
