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.
希瓦氏菌MR-1是一种兼性厌氧菌，已知其能将代谢过程中产生的电子转移到各种金属离子上，并在细菌表面产生纳米颗粒。在本研究中，我们追踪了希瓦氏菌细胞表面金纳米颗粒（Au NPs）的形成，并通过光谱法、zeta电位分析和电子显微镜研究了膜蛋白和细胞外多糖在此过程中的作用。
