Abstract:
Bioproduced nanoparticles (NPs) are attracting significant interest due to their potential advantages in safety, environmental footprint, and unique properties. This study explores the application of microbial fuel cells (MFCs) as a screening tool to expedite the discovery of biomanufacturing strains for sustainable nanoparticle production These bioelectrochemical devices harness the electron transfer abilities of electroactive microorganisms, often metal reducers, to generate electricity from organic matter. The ability to donate electrons during metabolism makes these bacteria prime candidates for biogenic nanoparticle synthesis. This approach leverages the inherent connection between bacterial electron flow and potential nanoparticle production mechanisms. By monitoring the electrical output of MFCs inoculated with different bacterial cultures, researchers can potentially identify those with enhanced electron transfer associated with nanoparticle synthesis. This offers a rapid and simple initial screening method compared to traditional techniques.
