Crystallochemical Control of Iron Oxide Biomineralizationree mineral phases, ferrihydrite (Fe.O..nH.O), goethite (.-FeOOH) and magnetite (Fe.O.) will be discussed. Emphasis will be placed on the mechanisms by which organisms regulate the structure, morphology, size and organization of iron oxide biominerals and how these processes result in functional ada

Anaerobic Production of Single-Domain Magnetite by the Marine, Magnetotactic Bacterium, Strain MV-1ia (Blakemore, 1975). These microorganisms represent a morphologically diverse group of bacteria that are ubiquitous in aquatic habitats and are apparently worldwide in distribution (Blakemore, 1982; Blakemore et al., 1989). Despite their ubiquity, the magnetotactic bacteria have proven notoriously

Application of Bacterial Magnetite particles consisting of magnetite with controlled size (500–1000 Å). The bacterial magnetites were aligned in 10 to 30 particles, and were covered with organic thin films. Since it is difficult to culture magnetotactic bacteria on a large scale, these bacterial magnetites have thus far not been use

Observations of Magnetosome Organization, Surface Structure, and Iron Biomineralization of Undescribprokaryotes which have the ability to produce intracellular biominerals. In the 15 years since they were discovered (10), these organisms have been found in environments ranging from freshwater to hypersaline, aerobic to anoxic, but usually in microaerophilic zones (6, 11, 21, 31, 50, 53, 71, 76).

Sequence analysis of the amplified, cloned DNA indicated that . MS1 belongs in the alpha purple eubacterial phylogenetic group. Nucleotide sequence obtained from rev

Iron Mineralization by Bacteria: Metabolic Coupling of Iron Reduction to Cell Metabolism in , Strainil and sedimentary environments, iron oxides and oxyhydroxides have a great potential for interacting with both organisms and the chemical environment. Not only is Fe(III) the most abundant electron acceptor in most soils (Ponnamperuma, 1972), but it is second only to sulfate as the most abundant el

Structural and Morphological Characterization of Biogenic Magnetite Crystalschitons use a specialized tongue or radula, which is in effect a conveyor belt of mineralized teeth, to graze on the algae that adhere to intertidal rocks. Chiton teeth are capped with magnetite, the hard iron oxide retarding attrition. Magnetite has since been identified in metazoan species (Gould
