Magnetosome formation in prokaryotes
Magnetotactic bacteria were discovered almost 30 years ago, and for many years and many different reasons, the number of researchers working in this field was few and progress was slow. Recently,Expand
Rock magnetic criteria for the detection of biogenic magnetite
Abstract We report results on the magnetic properties of magnetites produced by magnetotactic and dissimilatory iron-reducing bacteria. Magnetotactic bacterial (MTB) strains MS1, MV1 and MV2 andExpand
Magneto-aerotaxis in marine coccoid bacteria.
Magnetotactic cocci swim persistently along local magnetic field lines in a preferred direction that corresponds to downward migration along geomagnetic field lines. Recently, high cellExpand
Multiple Evolutionary Origins of Magnetotaxis in Bacteria
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 mostExpand
Spatiotemporal Distribution of Marine Magnetotactic Bacteria in a Seasonally Stratified Coastal Salt Pond
ABSTRACT The occurrence and distribution of magnetotactic bacteria (MB) were studied as a function of the physical and chemical conditions in meromictic Salt Pond, Falmouth, Mass., throughout summerExpand
Biologically Induced Mineralization by Bacteria
Bacteria are small, prokaryotic, microorganisms that are ubiquitous in surface and subsurface terrestrial and aquatic habitats. Prokaryotes comprise two Domains (Superkingdoms) in the biologicalExpand
Magnetite from magnetotactic bacteria; size distributions and twinning
We studied intracellular magnetite particles produced by several morphological types of magnetotactic bacteria including the spirillar (helical) freshwater species, Magnetospirillum magnetotacticum,Expand
Electron microscopy study of magnetosomes in a cultured coccoid magnetotactic bacterium
Intracellular magnetite (Fe3O4) crystals produced by the magnetotactic bacterium MC-1 were analysed by transmission electron microscopy (TEM). Strain MC-1 represents the first-reported isolation of aExpand
Biomineralization of ferrimagnetic greigite (Fe3S4) and iron pyrite (FeS2) in a magnetotactic bacterium
THE ability of magnetotactic bacteria to orientate and navigate along geomagnetic field lines is due to the controlled intracellular deposition of the iron oxide mineral, magnetite (Fe3O4)1,2. TheExpand
Anaerobic magnetite production by a marine, magnetotactic bacterium
Bacterial production of magnetite represents a significant contribution to the natural remanent magnetism of deep-sea and other sediments1–5. Because cells of the freshwater magnetotactic bacteriumExpand
