    Magnetotactic bacteria accumulate a large pool of iron

    Staining with this probe suggests that unmineralized reduced iron is found in the cytoplasm and associated with magnetosomes Our results demonstrate that under our experimental conditions AMB1 is able to accumulate a large pool of iron distinct from magnetite Finally we discuss the biochemical and geochemical implications of these results
