What are Microbial Electrochemical Technologies?

Microbial electrochemical technologies (METs) link a microbial metabolism to an electrochemical system.

METs have a variety of different configurations and potential applications in diverse areas such as bioremediation, wastewater treatment, biotechnological productions, biosensing and many more. The most well known examples of these technologies are Microbial Fuel Cells (MFCs), which generate electrical current by harnessing bacterial metabolism. Electrode-respiring bacteria, capable of donating electrons to negatively poised electrodes, drive electrons from a useable substrate (often proposed as wastewater) through a circuit that ultimately reduces a terminal electron acceptor. This process is very similar to the natural respiration metabolism bacteria use to produce energy. Produced bacterial current can be harnessed for work if a load is added to the circuit. 

In other applications, not the generation of electrical power is the focus goal but the link microbial electrochemical activity with target chemical productions, for example with Microbial Electrolysis Cells or Microbial Electrosynthesis Cells. In some cases, like bioremediation, the connection to an electrochemical system enables to drive new metabolic reactions, which are of technological or environmental interest.

A number of different mechanisms allow bacteria to respire with charged electrodes but also to consume electrons from an electrode and include: direct via outer-membrane or extracellular proteins, and mediator-based via endogenous or exogenous mediators. Thus, MET research stretches from fundamental to very applied research and from deciphering and engineering microbial physiology via developing and testing interphase materials (such as electrodes and membranes) to designing and engineering applied MET systems.

ISMET lives through the engagement of its community members and is steered by the ISMET Board and organized by ISMET Committees. Every year one third of the ISMET Board members roll of and new community members are elected to serve on the Board.

Dr. Michaela TerAvest is an Associate Professor in the Department of Biochemistry and Molecular Biology at Michigan State University. She received her PhD in 2014 from Cornell University (with Dr. Lars Angenent) and was a postdoctoral researcher at UC Berkeley and Lawrence Berkeley National Lab (with Dr. Caroline Ajo-Franklin) until moving to MSU in 2015. Her research group engineers bacteria for biofuel and bioproduct generation, with a special focus on microbial electrochemical technologies involving Shewanella oneidensis. Dr. TerAvest has been recognized for both research and teaching accomplishments through a variety of awards, including a Beckman Young Investigator Award and MSU’s all-university Teacher-Scholar award. 

Europe

Marianna Villano

Dr. Marianna Villano is Assistant Professor of Chemical Engineering at the Department of Chemistry of Sapienza University of Rome (Italy). She earned her PhD in Industrial Chemical Processes in 2011, from the same University. Her journey in the world of Microbial Electrochemical Technologies (MET) started during the PhD, when she also spent six months at the Department of Biological and Environmental Engineering of the Cornell University (Ithaca, NY, USA) in the laboratory of Professor L.T. Angenent. Her main research activity focuses on the treatment and simultaneous valorization of waste and wastewater by means of biological processes, primarily exploiting mixed microbial cultures. These include MET for biogas upgrading, nitrogen removal and recovery, control of the products spectrum during the acidogenic fermentation (i.e., electro-fermentation), as well as the electrosynthesis of valuable products from the reduction of carbon dioxide.
