Special Issue Information

Dear Colleagues,

The application of microbial fuel cell (MFC) technology in biosensors is gaining increasing interest from the scientific community. MFCs offer unique and attractive features of low cost, fast response time, ease of signal measurement and interpretation, and long-term operation due to the regeneration of electroactive bacteria, which makes them ideal for environmental applications.

MFC biosensors have proven their capability for immediate measurement and monitoring of organic matter in various environments. These devices have also been demonstrated to work as early warning systems through the detection of toxic compounds. Furthermore, due to electricity generation, they can work in an entirely self-powered and autonomous manner.

This exciting field spans many research areas and several challenges are still waiting to be addressed in either improving or extending upon existing concepts within the area.

It is therefore my pleasure to invite you to submit your work to this Special Issue, which is devoted to progress in the development of microbial fuel cell-based biosensors, covering both fundamental and applied aspects towards their practical implementation. The manuscripts on design, operation, electrode and bio-electrode development, microbial communities, stability and selectivity improvements, proof of concept and overall performance validation studies are highly welcome, but not limited to.

Sustainable technologies for energy production and storage are currently in great demand. Bioelectrochemical systems (BESs) offer promising solutions for both. Several attempts have been made to improve carbon felt electrode characteristics with various pretreatments in order to enhance performance. This study was motivated by gaps in current knowledge of the impact of pretreatments on the enrichment and microbial composition of bioelectrochemical systems. Therefore, electrodes were treated with poly(neutral red), chitosan, or isopropanol in a first step and then fixed in microbial electrolysis cells (MECs). Four MECs consisting of organic substance-degrading bioanodes and methane-producing biocathodes were set up and operated in batch mode by controlling the bioanode at 400 mV vs. Ag/AgCl (3M NaCl). After 1 month of operation, Enterococcus species were dominant microorganisms attached to all bioanodes and independent of electrode pretreatment. However, electrode pretreatments led to a decrease in microbial diversity and the enrichment of specific electroactive genera, according to the type of modification used. The MEC containing isopropanol-treated electrodes achieved the highest performance due to presence of both Enterococcus and Geobacter. The obtained results might help to select suitable electrode pretreatments and support growth conditions for desired electroactive microorganisms, whereby performance of BESs and related applications, such as BES-based biosensors, could be enhanced.
