Research has demonstrated that the metabolic activity of pathogens on the electrode surface is associated with electric current generation via extracellular electron transfer (EET). This chapter introduces work studying the correlation between the pathogen's current production capability and metabolism activity. Single potential amperometry (SA) is a technique that evaluates the effects of drugs on the biofilm metabolism. We discuss methods that complement SA to capture microbial metabolic activity. Potential EET mechanisms and metabolic models facilitate the understanding of microbial current production. Current limitations and the potential of high-throughput SA-based drug screening are also discussed.","The rapid emergence of antibiotic resistance in pathogenic biofilms has intensified interest in developing novel antibiotic drugs and methods to measure the metabolic activity of biofilms.

While SRB are generally considered to utilize diffusive organics and gases (e.g., hydrogen) as the electron donors, recent studies revealed that some SRB can use extracellular insoluble solids (e.g., electrodes and partner microbial cells in a consortium) as electron donors for energy acquisition. However, the mechanism had been ambiguous for a decade, due to the difficulty to distinguish electron uptake reaction and hydrogen evolution on the surface of solids. This chapter summarizes research backgrounds and electrochemical methods and shows example studies regarding the extracellular electron uptake mechanisms and thermodynamics in SRB. These aspects have critical implications in SRB physiology, biogeological and biophysical processes, and anaerobic iron corrosion.","Sulfate-reducing bacteria (SRB) are ubiquitous in anaerobic environments, particularly in marine sediments, and play crucial roles in the biogeochemical cycling of carbon, sulfur, and metals, the biosynthesis of minerals, and anaerobic metal corrosion.
