Maximizing electron transfer in microbiological fuel cells
We are happy to announce that our newest work has been just published in ACS Sustainable Chemistry and Engineering!
Shewanella oneidensis MR-1 is an electroactive bacterium commonly employed in the design of microbial fuel cells (MFCs) due to its ability to convert organic matter to electricity. Its applicability is limited by low adhesion to the surface of the electrode, which decreases the efficiency of charge transfer and reduces the available power outputs. In this study, we aimed to improve the adhesion, viability, and extracellular charge transfer ability of S. oneidensis on the surface of electrodes modified with poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), which is a conducting polymer frequently used to enhance the performance of MFCs. Our approach shows promise in the further development of efficient renewable energy technology for bioelectricity generation.
