Growth and cell fractions of the magnetic bacterium Magnetospirillum gryphiswaldense were studied by Mössbauer spectroscopy. In isolated magnetosomes only magnetite particles were observed. The membrane fraction of Magnetospirillum gryphiswaldense contains a ferritin-like component and a Fe2+ species and also magnetite particles smaller than those observed in the magnetosomes fraction. In the cytosol only ferritin was identified. © 2010 IOP Publishing Ltd.
