Magnetotactic bacteria optimally navigate natural pore networks [PDF]
eLifeMagnetotactic bacteria swim along geomagnetic field lines to navigate the pore spaces of water-saturated sediment. To understand the physical basis for efficient navigation in confined geometries, we observe the motion of multicellular magnetotactic ...

Incorporation of Tb and Gd improves the diagnostic functionality of magnetotactic bacteria [PDF]
Materials Today Bio, 2023 Magnetotactic bacteria are envisaged as potential theranostic agents. Their internal magnetic compass, chemical environment specificity and natural motility enable these microorganisms to behave as nanorobots, as they can be tracked and guided towards ...

Magnetotactic Bacteria from Extreme Environments [PDF]
Life, 2013 Magnetotactic bacteria (MTB) represent a diverse collection of motile prokaryotes that biomineralize intracellular, membrane-bounded, tens-of-nanometer-sized crystals of a magnetic mineral called magnetosomes.

Physiological magnetic field strengths help magnetotactic bacteria navigate in simulated sediments [PDF]
eLifeBacterial motility is typically studied in bulk solution, while their natural habitats often are complex environments. Here, we produced microfluidic channels that contained sediment-mimicking obstacles to study swimming of magnetotactic bacteria in a ...

Detection of interphylum transfers of the magnetosome gene cluster in magnetotactic bacteria [PDF]
Frontiers in Microbiology, 2022 Magnetosome synthesis in magnetotactic bacteria (MTB) is regarded as a very ancient evolutionary process that dates back to deep-branching phyla. Magnetotactic bacteria belonging to one of such phyla, Nitrospirota, contain the classical genes for the ...

Current view of iron biomineralization in magnetotactic bacteria [PDF]
Journal of Structural Biology: X, 2021 Biomineralization is the process of mineral formation by living organisms. One notable example of these organisms is magnetotactic bacteria (MTB). MTB are Gram-negative bacteria that can biomineralize iron into magnetic nanoparticles. This ability allows
