Magnetobacterium
a magnetic rod.
Rod‐shaped, large, magnetic cells occurring in freshwater sediments. The original description is based on bacteria enriched from the littoral sediment of a freshwater lake in Southern Germany (Chiemsee); similar types of bacteria were also observed in sediments of other freshwater lakes and ponds in Southern Germany and Brazil. Counts of active bacteria in different vertical layers of Chiemsee sediment indicated that “
Candidatus
M. bavaricum” is a typical gradient organism, particularly adapted to zones characterized by low levels of oxygen, where it reaches the highest abundance (Spring et al., 1993). A minor fraction of these bacteria was also found in the anoxic zone, whereas high concentrations of oxygen can apparently not be tolerated by this bacterium over longer periods of time.
