EMR Spectra of Iron-Based Nanoparticles Produced by Dissimilatory Bacteria

Abstract:

We have studied electron magnetic resonance spectra of iron-oxide nanoparticles related to iron reduction metabolism of dissimilatory bacterium Thermincola ferriacetica. It is found that the resonance parameters of metabolic products change notably with time. The X-ray diffraction data indicates partial crystallization of iron oxide during long time storage under air open conditions.
