Magnetite and Magnetotaxis in Algae

 · Magnetite and Magnetotaxis in Algae. Magnetotactic algae of the genus Anisonema (Euglenophyceae) have been isolated from a coastal mangrove swamp in northeastern Brazil. The magnetotactic response is based on a permanent magnetic dipole moment per cell ∼7 10 -10 emu. Each cell contains many magnetite (Fe 3 O 4) particles organized in chains.
