Bacteria with motility directed by the local geomagnetic field have been observed in marine sediments. These magnetotactic microorganisms possess flagella and contain novel structured particles, rich in iron, within intracytoplasmic membrane vesicles. Conceivably these particles impart to cells a magnetic moment. This could explain the observed migration of these organisms in fields as weak as 0.5 gauss.

Magnetosome biogenesis in magnetotactic bacteria

This Review discusses the diverse properties of magnetosome biogenesis in other species of magnetotactic bacteria and considers the value of genetically 'magnetizing' non-magnetotacticacteria.

Observations on a magnetotactic bacteria-grazing ciliate in sediment from the intertidal zone of Huiquan Bay, China

The results suggest that this ciliated MRP can graze, ingest, and digest various types of MTB, and support the assertion that MRPs probably contribute to the ecological cycles of iron, and expand possibilities for research into the mechanism of magnetoreception in eukaryotes.

Magnetotaxis in Prokaryotes

Magnetotaxis refers to the behaviour of some motile, aquatic, bacteria that orient and swim along magnetic field lines, which are important in the cycling of a number of important elements including carbon, iron, nitrogen and sulfur.

Intercellular Junctions, Motility and Magnetosome Structure in a Multicellular Magnetotactic Prokaryote

A many-celled, magnetotactic, prokaryote obtained from brackish water possessed intercellular connections at points of contact between the outer membranes of constituent cells. These connections

Flagella and Swimming Behavior of Marine Magnetotactic Bacteria

Gen clusters, the flagellar apparatus architecture, and the swimming behavior of marine unicellular and multicellular magnetotactic bacteria are described and physiological significance and mechanisms that govern these motions are discussed.

Cell division in magnetotactic bacteria splits magnetosome chain in half

Direct Transmission Electron Microscopy evidence is reported that division occurs at a central point of the cell and the chain, cleaving the magnetosome chain in two, and the new magnetosomes chain relocates rapidly to the centre of the daughter cell.

Biology and Physics of Magnetotactic Bacteria

Theoretical and experimental studies show that magnetotactic bacteria swim following a trajectory similar to cylindrical helix, and have been observed avoiding regions with UV or violet-blue light of high intensity.

Isolation and characterization of a magnetotactic bacterial culture from the Mediterranean Sea.

This study reported the first axenic culture of magnetotactic bacteria isolated from the Mediterranean Sea, and showed that MO-1 flagella were powered by both proton-motive force and sodium ion gradient, which is a rare feature among bacteria.
