Abstract

Shewanella oneidensis MR-1 is a facultative anaerobic bacterium that is known to transfer electrons generated during metabolism to various metal ions and produce nanoparticles on the bacterial surface. In this study, we tracked the formation of gold nanoparticles (Au NPs) on the S. oneidensis cell surfaces and investigated the roles of membrane proteins and extracellular polysaccharides in this process by spectrometry, zeta potential analysis, and electron microscopy.
