“…The highly permeable materials have immense power density ( Figure 2) because of which more intricate surface zone is accessible for microbial colonization. The power yield is emphatically associated to anode surface region [21]. The cathodic zone, interestingly, has just a minor impact on power output [22].…”

“…To relate the results of the four-cluster plot to possible microbiological phenomena, we propose that Cluster 1a represents the inoculation of soil bacteria on the anode and cathode, biofilm formation, and voltage production; Cluster 2a represents the immediate decline of voltage from the disturbance from the injection, rapid increase, stabilization, and decline in voltage; Cluster 3a represents a stabilization period; and Cluster 4a represents continued stabilization (Li et al 2008;Rodrigo et al 2009;Sudarsan et al 2014). It is clear that Cluster 2 should be separated further into more phases that represent visual changes in the voltage.…”

Biotechnology offers new ways to use biological processes as environmental sensors. For example, in soil microbial fuel cells (MFCs), soil electro-genic microorganisms are recruited to electrodes embedded in soil and produce electricity (measured by voltage) through the breakdown of substrate. Because the voltage produced by the electrogenic microbes is a function of their environment, we hypothesize that the voltage may change in a characteristic manner given environmental disturbances, such as the contamination by exogenous material, in a way that can be modelled and serve as a diagnostic. In this study, we aimed to statistically analyze voltage from soil MFCs injected with urea as a proxy for gross contamination. Specifically, we used 𝘬-means clustering to discern between voltage output before and after the injection of urea. Our results showed that the 𝘬-means algorithm recognized 4–6 distinctive voltage regions, defining unique periods of the MFC voltage that clearly identify pre- and postinjection and other phases of the MFC lifecycle. This demonstrates that 𝘬-means can identify voltage patterns temporally, which could be further improve the sensing capabilities of MFCs by identifying specific regions of dissimilarity in voltage, indicating changes in the environment.

“…The cathode and anode were connected with a stainless wire (0.1 cm diameter, 5.0 cm length). The salt bridge gel was prepared according to previous studies [19,20] with minor modifications, i.e., 1.0 g/L of KCl and 10.0 g/L of agarose were used. The gel was sterilized at 121ºC for 15 mins.…”

Fungi produce various types of extracellular enzymes, including the copper-containing oxidative enzyme laccase. This enzyme uses gaseous oxygen (O 2) as an electron acceptor to catalyze oxidation of phenolic compounds, and therefore it can act as a cathode biocatalyst in a microbial fuel cell (MFC). In this study, a new model of the air-cathode microbial fuel cell (AC-MFC) was constructed. For its design, the laccase-producing yeast Galactomyces reessii cultured in potato dextrose agar was grown in the cathode chamber, and an anaerobic microbial community was maintained in the anode chamber in order to carry out sulfate removal and, simultaneously, generate electricity. Results showed that the cathode with G. reessii outperformed the cathode with sterile gel (negative control), yielding the maximum open circuit voltage of 550.65±14.92 mV, the maximum power density of 0.35±0.01 mW/m 3 , the maximum current density of 225.69±17.25 mA/m 3 and sulfate removal of 73.29±1.31%. This study demonstrated the feasibility of using a yeast culture for continuous laccase production in the cathode chamber of the AC-MFC in order to improve their electricity generation and sulfate removal.
