Habits of magnetosome crystals in coccoid magnetotactic bacteria.
نویسندگان
چکیده
High-resolution transmission electron microscopy and electron holography were used to study the habits of exceptionally large magnetite crystals in coccoid magnetotactic bacteria. In addition to the crystal habits, the crystallographic positioning of successive crystals in the magnetosome chain appears to be under strict biological control.

Crystal habits and magnetic microstructures of magnetosomes in coccoid magnetotactic bacteria.
We report on the application of off-axis electron holography and high-resolution TEM to study the crystal habits of magnetosomes and magnetic microstructure in two coccoid morphotypes of magnetotactic bacteria collected from a brackish lagoon at Itaipu, Brazil. Itaipu-1, the larger coccoid organism, contains two separated chains of unusually large magnetosomes; the magnetosome crystals have rou...
متن کاملMagnetic microstructure of bacterial magnetite by electron holography
A brackish lagoon at Itaipu, Brazil, contains magnetotactic bacteria with unusually large magnetite magnetosomes (lengths 100-200 nm). The micromagnetic structures of the magnetosomes from two different coccoid organisms from the lagoon have been determinedby electron holography.The results are consistentwith single-magnetic-domain structure in the elongated magnetosomes from one organism and m...

High resolution transmission electron microscopy was used to study the crystallographic habits of the elon gated magnetite crystals, variously described as bullet-, toothor arrowhead-shaped, in two recently de scribed, uncultured, magnetotactic bacteria belonging to the Nitrospirae phylum designated Candidatus Magnetoovum mohavensis strain LO-1, and Candidatus Thermomagnetovibrio paiutensis s...
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, ...
متن کاملReduced efficiency of magnetotaxis in magnetotactic coccoid bacteria in higher than geomagnetic fields.
Magnetotactic bacteria are microorganisms that orient and migrate along magnetic field lines. The classical model of polar magnetotaxis predicts that the field-parallel migration velocity of magnetotactic bacteria increases monotonically with the strength of an applied magnetic field. We here test this model experimentally on magnetotactic coccoid bacteria that swim along helical trajectories. ...
