Mossbauer Spectroscopy of Iron Biomineralization Products in Magnetotactic Bacteria
Mcissbauer spectroscopy is a nuclear i-rav resonance technique that has been extensively tv!i 'iill' s,,'stems. applied to the study of the electronic properties of iron in biological '. The power of the technique lies in its sensitivity to the effects of the physical environment (nature ]18 lw and disposition of ligands, magnetic structure, etc.) on 57Fe nuclei. Moreover, it is sensitive ' onl...

متن کاملDiversity and ecology of and biomineralization by magnetotactic bacteria.
Magnetotactic bacteria (MTB) biomineralize intracellular, membrane-bounded crystals of magnetite (Fe3 O4 ) and/or greigite (Fe3 S4 ) called magnetosomes. MTB play important roles in the geochemical cycling of iron, sulfur, nitrogen and carbon. Significantly, they also represent an intriguing model system not just for the study of microbial biomineralization but also for magnetoreception, prokar...
متن کاملMagnetic Properties of Magnetotactic Bacteria
This paper reports on the magnetic properties of magnetosomes in the freshwater magnetotactic bacterium Aquaspirillum nlllgnetOlaClicwn. The magnetosomes are well crystallized particles of magnetite with dimensions of 40 to 50 nm, which are arranged within cells in a single linear chain and are within the single-magnetic-domain (SO) size range for. magnetite. A variety of magnetic properties ha...
متن کاملGenetics and cell biology of magnetosome formation in magnetotactic bacteria.
The ability of magnetotactic bacteria (MTB) to orient in magnetic fields is based on the synthesis of magnetosomes, which are unique prokaryotic organelles comprising membrane-enveloped, nano-sized crystals of a magnetic iron mineral that are aligned in well-ordered intracellular chains. Magnetosome crystals have species-specific morphologies, sizes, and arrangements. The magnetosome membrane, ...
