Microbiology of Bioelectrochemical System
2020In the recent time more work is considered in bioelectrochemical system for obtaining power and wastewater treatment. In these systems many microbes are used to carry out the electron transfer from medium to the anode electrodes. These microbes are called electrogen since they have the capacity to transfer these electrons.

Application of redox mediators in bioelectrochemical systems
Biotechnology Advances, 2018Redox mediators (RM) are natural or artificial compounds used by microorganisms as electron acceptors and electron donors during electron transfer. Evidence collected in the last years indicates that the application of RM in bioelectrochemical systems (BES) enhanced the electron transfer from microorganisms to anodes and from cathodes to microorganisms.

2-Bromoethanesulfonate degradation in bioelectrochemical systems
Bioelectrochemistry, 20152-Bromoethanesulfonate (BES) is the most reported chemical inhibitor for methanogenesis in laboratory-scale bioelectrochemical systems. However, there is doubt about BES's long-term effectiveness in microbial fuel cells (MFCs). We observed BES degradation in MFCs, whereas not in microbial electrolysis cells (MECs).

Bioelectrochemical Systems: An Outlook for Practical Applications
ChemSusChem, 2012AbstractBioelectrochemical systems (BESs) hold great promise for sustainable production of energy and chemicals. This review addresses the factors that are essential for practical application of BESs. First, we compare benefits (value of products and cleaning of wastewater) with costs (capital and operational costs).

Biocathodic Nitrous Oxide Removal in Bioelectrochemical Systems
Environmental Science & Technology, 2011Anthropogenic nitrous oxide (N(2)O) emissions represent up to 40% of the global N(2)O emission and are constantly increasing. Mitigation of these emissions is warranted since N(2)O is a strong greenhouse gas and important ozone-depleting compound. Until now, only physicochemical technologies have been applied to mitigate point sources of N(2)O, and no ...

A bioelectrochemical system (BES) exploits biological catalysts for anode and/or cathode reactions, or both. This chapter focuses on three different classes of microbial bioelectrocatalysts which can be distinguished, ranging from single enzymes (e.g., dehydrogenases) or enzyme arrays and organelles (e.g., mitochondria) to entire living microbial cells.

Role of membranes in bioelectrochemical systems
Membrane Water Treatment, 2015This paper provides an overview of the role of membranes in bioelectrochemical systems (BESs). Bioelectrochemical systems harvest clean energy from waste organic sources by employing indigenous exoelectrogenic bacteria. This energy is extracted in the form of bioelectricity or valuable biofuels such as ethanol, methane, hydrogen, and hydrogen peroxide.
