Geobiology of marine magnetotactic bacteria
Magnetotactic bacteria (MTB) biomineralize intracellular membrane-bound crystals of magnetite (Fe3O4) or greigite (Fe3S4), and are abundant in the suboxic to anoxic zones of stratified marine environments worldwide. Their population densities (up to 105 cells ml−1) and high intracellular iron …

Genomic Diversity of Magnetotactic Bacteria from Underexplored Extreme Aquatic Habitats
Magnetotactic bacteria (MTB) are metabolically versatile prokaryotes characterised by their ability to biomineralise intracellular magnetic nanocrystals within organelles called magnetosomes. These organelles assist MTB to align with geomagnetic field lines using magnetotaxis, thereby facilitating …

The redox and iron-sulfide geochemistry of Salt Pond and the thermodynamic constraints on native magnetotactic bacteria
… the interface. This chemocline is a habitat for magnetotactic bacteria (MB), and the spatial and temporal distribution of MB in the system along with geochemical (Fe2+, H2S, pH, O2 (aq), etc.) profiles have been analyzed from 2002 - 2005. It has been previously observed that magnetite-producing …

Engineering bacterial magnetic nanoparticles
Magnetosomes, produced by magnetotactic bacteria (MTB), are the most attractive alternative source of non-toxic biocompatible magnetic nanoparticles (MNPs). A magnetosome contains Fe2O4 magnetite with properties superior to MNPs synthesized by the traditional chemical route. However, synthesis of …

Forming magnetic chain with the help of biological organisms
… can interact and assemble in chains or networks. Magnetotactic bacteria are one of the most interesting microorganisms, in which the assembly of nanoparticles occurs. These microorganisms are a heterogeneous group of gram negative prokaryotes, which all show the production of special magnetic …

Formation and alteration of magnetite nanoparticles
… on magnetite formation was investigated. Magnetotactic bacteria¬¬ are able to synthesize and align magnetite nanoparticles of well-defined size and morphology due to the involvement of special proteins with specific binding properties. Based on this model of morphology control, phage …

Confinement-mediated accumulation and collective dynamics of microswimmers
… experimental setup to investigate suspensions of magnetotactic bacteria. The experiments were carried out during a visit to the group of Prof. Kari Dalnoki-Veress (McMaster University). These bacteria synthesize nanomagnets in their cytoplasm and align passively with external magnetic fields as …

On structural properties of magnetosome chains
Magnetotaktische Bakterien besitzen eine intrazelluläre Struktur, die Magnetosomenkette genannt wird. Magnetosomenketten enthalten Nanopartikel von Eisenkristallen, die von einer Membran umschlossen und entlang eines Zytoskelettfilaments ausgerichtet sind. Dank der Magnetosomenkette ist es …
