A facultative dissimilatory metal-reducing bacterium,
Shewanella sp. strain HN-41, was used to produce magnetite
nanoparticles from a precursor, poorly crystalline ironoxyhydroxide
akaganeite (β-FeOOH), by reducing Fe(III).
The diameter of the biogenic magnetite nanoparticles ranged
from 26 nm to 38 nm, characterized by dynamic light
scattering spectrophotometry. The magnetite nanoparticles
consisted of mostly uniformly shaped spheres, which were
identified by electron microscopy. The magnetometry
revealed the superparamagnetic property of the magnetic
nanoparticles. The atomic structure of the biogenic
magnetite, which was determined by extended X-ray
absorption fine structure spectroscopic analysis, showed
similar atomic structural parameters, such as atomic
distances and coordinations, to typical magnetite mineral.
