Description
Understanding electroactive biofilms is essential to advance the development of microbial fuel cells (MFCs), biological wastewater treatment, and to comprehend the bacterial communication pathways. Although decades of research have investigated electroactive bacteria (EAB), particularly G. sulfurreducens and S. oneidensis, the exact electron transfer mechanisms between EAB and electrodes remain poorly understood.1
This presentation highlights square-wave voltammetry (SWV) as a powerful, yet often-overlooked technique, to investigate early-stage biofilm formation and elucidate these electron transfer pathways (Fig. 1). Furthermore, these results are contextualized with traditional cyclic voltammetry.2 This comparative analysis provides new insights into how biofilms exchange electrons with the electrode interface.
