Magnetite and magnetotaxis in microorganisms

Bioelectromagnetics. 1989;10(3):223-37. doi: 10.1002/bem.2250100303.

Abstract

Magnetotactic bacteria from freshwater and marine sediments orient and navigate along geomagnetic field lines. Their magnetotactic response is based on intracellular, single magnetic domains of ferrimagnetic magnetite, which impart a permanent magnetic dipole moment to the cell.
