Magnetite and Magnetotaxis in Algae
Biophysical Journal, 1986 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 approximately 7 10(-10) emu. Each cell contains many magnetite (Fe(3)O(4)) particles organized in chains.

Magnetic genes: Studying the genetics of biomineralization in magnetotactic bacteria. [PDF]
, 2020 Many species of bacteria can manufacture materials on a finer scale than those that are synthetically made. These products are often produced within intracellular compartments that bear many hallmarks of eukaryotic organelles.

Multiple Evolutionary Origins of Magnetotaxis in Bacteria
Science, 1993 Magnetosomes are intracellular, iron-rich, membrane-enclosed magnetic particles that allow magnetotactic bacteria to orient in the earth's geomagnetic field as they swim. The magnetosomes of most magnetotactic bacteria contain iron oxide particles, but some magnetotactic species contain iron sulfide particles instead.

Carbon sequestration assessment using varying concentrations of magnetotactic bacteria
Environmental Advances, 2022 Carbon cycling processes on Earth are many and complex, and several continental and oceanic environments remain poorly studied. Consequently, major uncertainties affect carbon-cycling models which limit our ability to understand and predict climate ...

Destabilization of a flow focused suspension of magnetotactic bacteria
, 2016 Active matter is a new class of material, intrinsically out-of equilibrium with intriguing properties. So far, the recent upsurge of studies has mostly focused on the spontaneous behavior of these systems --in the absence of external constraints or ...
