“…Finally, note that the biological literature often uses the term "direct electron transfer" for the case when the redox mediators are endogenous, since no external redox mediator was added to the described experiments ( Figure 5) [120]. However, from the standpoint of an electrochemist the exogenous and endogenous situations are identical, with nether being considered "direct" electron transfer as they both involve a redox mediator.…”

Microbiologically influenced corrosion (MIC) is a major concern in a wide range of industries, with claims that it contributes 20% of the total annual corrosion cost. The focus of this present work is to review critically the most recent proposals for MIC mechanisms, with particular emphasis on whether or not these make sense in terms of their electrochemistry. It is determined that, despite the long history of investigating MIC, we are still a long way from really understanding its fundamental mechanisms, especially in relation to non-sulphate reducing bacterial (SRB) anaerobes. Nevertheless, we do know that both the cathodic polarization theory and direct electron transfer from the metal into the cell are incorrect. Electrically conducting pili also do not appear to play a role in direct electron transfer, although these could still play a role in aiding the mass transport of redox mediators. However, it is not clear if the microorganisms are just altering the local chemistry or if they are participating directly in the electrochemical corrosion process, albeit via the generation of redox mediators. The review finishes with suggestions on what needs to be done to further our understanding of MIC.

“…Moreover, electrically active yeast strains are also reported such as Saccharomyces cerevisae and Hansenula anomela. Sulfate-reducing-bacteria and dissimilatorymetal-reducing-bacteria are reported as primary players with significant contributions to bioanode (9). Few studies investigated Gram-positive bacteria to be more useful in EAB formation.…”

Microbial fuel cell (MFC) is a promising technology for wastewater treatment coupled with electricity generation. Biowaste-derived electrodes are used to improve the surface area, roughness, and hydrophilicity, which play pivotal role in the enhanced biofilm formation. In the present study, Ficus religiosa leaves (FRL) biowaste was used to develop the bioelectrode. In this study, Congo red (CR) dye decolorization was performed using MFC, wherein the effect of dye decolorization with respect to dye concentration, glucose concentration, and hydraulic retention time (HRT) was studied. The surface roughness and distribution of carbon powder on carbon cloth were confirmed using scanning electron microscope (SEM) analysis. Also, Bacillus subtilis adhesion and chain-like structure formation on the electrode confirmed the biofilm formation on the electrode. The polarization curve was performed to assess the MFC performance. The maximum power density of 70.50 mW/m 2 and current density of 251.79 mA/m 2 at 2,224 Ω was achieved. The maximum decolorization of 80.95 ± 2.08% and COD reduction of 73.96 ± 1.76% were obtained, respectively, after complete treatment of MFC for 54 h. UV-visible spectrometry analysis of dye contained samples during MFC treatment at various time intervals was confirmed the cleavage of azo bond (N N), and the corresponding peak intensity variation was noticed at 490 nm.
