Magnetosomes and Magneto-Aerotaxis

, 2009
Magnetotactic bacteria orient and migrate along geomagnetic field lines. Magneto-aerotaxis increases the efficiency of respiring microaerophilic cells to efficiently find and maintain a position at a preferred microaerobic oxygen concentration.

Characterization of the bacterial magnetosome membrane [PDF]

Journal of Bacteriology, 1988
Intact magnetosomes of Aquaspirillum magnetotacticum were purified from broken cells by a magnetic separation technique. Electron microscopic and chemical analyses revealed the magnetite to be enclosed by a lipid bilayer admixed with proteins.

Investigation of pharmacokinetics and immunogenicity of magnetosomes

Artificial Cells, Nanomedicine, and Biotechnology
Magnetosomes are iron oxide or iron sulphide nano-sized particles surrounded by a lipid bilayer synthesised by a group of bacteria known as magnetotactic bacteria (MTB). Magnetosomes have become a promising candidate for biomedical applications and could

Comparing Paleointensity Recording Efficiencies of Detrital and Biogenic Magnetite by Deposition Experiments With Synthetic Sediments

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Marine sediments contain magnetic mineral particles of detrital, biogenic and authigenic origin that record changes in the direction and intensity of the geomagnetic field over geological time. Previous studies have demonstrated that the recording efficiencies of detrital and biogenic magnetite differ.
