Magnetotactic bacteria (MTB) are a diverse group of microorganisms that orient and navigate along magnetic fields due to the presence of intracellular structures known as magnetosomes. These magnetosomes contain magnetic iron minerals such as magnetite (Fe3O4) or greigite (Fe3S4) and are organized in chains within the bacterial cell. This unique property allows the bacteria to align themselves with the Earth's magnetic field, aiding in their movement, especially in aquatic environments.
