TL;DR: High-resolution scanning and transmission electron microscopy study of surface textures and internal structures of selected carbonate globules show that the globules contain fine-grained, secondary phases of single-domain magnetite and iron sulfides.
Journal ArticleDOI
Occurrence of magnetic bacteria in soil
TL;DR: It is suggested that magnetic bacteria and their magnetofossils14 can contribute to the magnetic properties of soils.
Journal ArticleDOI
Fossil bacterial magnetite in deep-sea sediments from the South Atlantic Ocean
TL;DR: In this paper, the authors used rock-magnetic diagnostic methods to characterize the magnetic phases in deep-sea sediments from the South Atlantic; these phases were then extracted and studied with the electron microscope.
Journal ArticleDOI
Magnetosome vesicles are present before magnetite formation, and MamA is required for their activation.
TL;DR: Together, these results suggest that the magnetosome precisely coordinates magnetite biomineralization and can serve as a model system for the study of organelle biogenesis in noneukaryotic cells.
Journal ArticleDOI
Comprehensive genetic dissection of the magnetosome gene island reveals the step-wise assembly of a prokaryotic organelle
TL;DR: A comprehensive functional analysis of the MAI genes in a magnetotactic bacterium, Magnetospirillum magneticum AMB-1, shows that magnetosomes are assembled in a step-wise manner in which membrane biogenesis, magnetosome protein localization, and biomineralization are placed under discrete genetic control.
