Molecular composition determines the adsorption behaviors of loosely- and tightly-bound extracellular polymeric substances (EPS) from Shewanella oneidensis MR-1 on hematite nanoparticles

Extracellular polymeric substances (EPS) on the surface of dissimilatory iron-reducing bacteria (DIRB) play a crucial role in bacterial colonization and iron bioreduction. The surface EPS has a doubled-layer structure, consisting...
