Abstract:

Magnetotactic bacteria MTB biomineralize intracellular membrane-bound crystals of magnetite Fe304 or greigite Fe3S4, and are abundant in the suboxic to anoxic zones of stratified marine environments worldwide. Their population densities up to 105 cells ml-1 and high intracellular iron content suggest a potentially significant role in iron cycling, but very little is known about their population dynamics and regulation by environmental geochemistry.
