Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.A novel marine magnetotactic coccus, strain HHB‐1, was isolated from intertidal sediments in Houhai Bay, China. HHB‐1 cells are large coccoid–ovoid bacteria that contain multiple chains of prismatic magnetite magnetosomes and conspicuous Ca/Mg‐rich polyphosphate granules.

PLoS ONE, 2020 Magnetotactic bacteria (MTB) are prokaryotes that sense the geomagnetic field lines to geolocate and navigate in aquatic sediments. They are polyphyletically distributed in several bacterial divisions but are mainly represented in the Proteobacteria.

Magnetosome vesicles are present before magnetite formation, and MamA is required for their activation [PDF]
, 2004 Bacterial magnetosomes are intracellular compartments that house highly ordered magnetite crystals. By using Magnetospirillum sp. AMB-1 as a model system, we show that magnetosome vesicles exist in the absence of magnetite, biomineralization of magnetite

Intracellular inclusions of uncultured magnetotactic bacteria.
International microbiology : the official journal of the Spanish Society for Microbiology, 2005 Magnetotactic bacteria produce magnetic crystals in organelles called magnetosomes. The bacterial cells may also have phosphorus-containing granules, sulfur globules, or polyhydroxyalkanoate inclusions. In the present study, the ultrastructure and elemental composition of intracellular inclusions from uncultured magnetotactic bacteria collected in a ...

The Role of Fe(II) Minerals in Carbon Stabilization in Coastal and Estuarine Anoxic Environments
Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.Abstract Fe(III) (oxyhydr)oxides are well‐known for their role in organic carbon (OC) stabilization in terrestrial soils. Coastal and estuarine soils typically act as iron sinks and receive a high input of OC. However, tidal submersion induces anoxic and reducing conditions that favor the microbial reductive dissolution of Fe(III) (oxyhydr)oxides ...

Magnetotactic bacteria, magnetosomes and their application
Microbiological Research, 2012 Magnetotactic bacteria (MTB) are a diverse group of microorganisms with the ability to orient and migrate along geomagnetic field lines. This unique feat is based on specific intracellular organelles, the magnetosomes, which, in most MTB, comprise nanometer-sized, membrane bound crystals of magnetic iron minerals and organized into chains via a ...

A Comparison between Chemical Synthesis Magnetite Nanoparticles and Biosynthesis Magnetite
Bioinorganic Chemistry and Applications, 2014 The preparation of Fe3O4 from ferrous salt by air in alkaline aqueous solution at various temperatures was proposed. The synthetic magnetites have different particle size distributions.

Ferromagnetism in two mouse tumours [PDF]
, 1982 A variety of living organisms has been found recently that are biochemically able to precipitate the ferromagnetic mineral magnetite (Fe3O4). Originally discovered in the radular teeth of a primitive marine mollusc (Lowenstam, 1962), magnetite has since ...

Production of single-domain magnetite throughout life by sockeye salmon, Oncorhynchus nerka [PDF]
, 1988 Although single-domain particles of biogenic magnetite have been found in different species of pelagic fishes, nothing is known about when it is synthesized, or about whether the time during life when it is produced is correlated with the development of
