Fungi are among the microorganisms able to generate electricity as a result of their metabolic processes. Throughout the last several years, a large number of papers on various microorganisms for current production in microbial fuel cells (MFCs) have been published; however, fungi still lack sufficient evaluation in this regard. In this review, we focus on fungi, paying special attention to their potential applicability to MFCs. Fungi used as anodic or cathodic catalysts, in different reactor configurations, with or without the addition of an exogenous mediator, are described. Contrary to bacteria, in which the mechanism of electron transfer is pretty well known, the mechanism of electron transfer in fungi-based MFCs has not been studied intensively. Thus, here we describe the main findings, which can be used as the starting point for future investigations. We show that fungi have the potential to act as electrogens or cathode catalysts, but MFCs based on bacteria–fungus interactions are especially interesting. The review presents the current state-of-the-art in the field of MFC systems exploiting fungi.

“…The electrochemically active microbes release electrons to anode through oxidizing biodegradable organics in the anode chamber of MFC . The concomitants including H + ions and metabolic organic acids are produced and migrated to the opposite direction by electromigration and electroosmosis . The oxygen molecule (O 2 ) is one of the most selected electron acceptors due to its easy accessibility and high standard redox potential .…”

Improper management of dumped tailings not only causes a potential waste of resources but also poses a direct threat to the lives of local residents. A dual‐chamber microbial fuel cell (MFC) combining with the bioleaching technique was used in the study to extract Cu from the secondary mine tailings at a fed‐batch scale. A mixed culture of acidophilic bacteria was enriched and isolated from the acidic drainage in a copper mine. The effects of the pulp densities and initial pH on both the bio‐electronic performances and the recoveries of Cu on bio‐electrochemical platform were comparatively investigated. An appropriate increase in the pulp densities and a suitable decrease in the initial pH facilitated increases in power generations and enhanced the recoveries of Cu from the tailing samples. The maximum power density of 30.54 mW/m2 was achieved in the coupling system with the coulomb efficiency of 4.52%, and the internal resistance of 166.58 Ω being synchronously obtained. Correspondingly, the highest recovery efficiency of Cu of 78.72% was got in the two‐dimensional tests under conditions including the pulp density (w/v) of 20% and the initial pH of 1.8. The electrochemical reduction and the chemical precipitation in MFCs were confirmed as two of main mechanisms in obviously influencing the recovery of Cu. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019
