Magnetotactic bacteria (MTB) are a group of Gram-negative prokaryotes that respond to the geomagnetic field. This unique property is attributed to the biosynthesis of magnetic nanoparticles within MTB’s magnetosomes, an intracellular organelle with magnetic iron-bearing nanocrystals. This review summarizes the most recent studies on different aspects of MTB including the characterization of magnetosomes and applications of the environmental pollutant control or remediation. The morphologic and phylogenetic diversity of MTB are introduced with a review of isolation and cultivation methods. MTB as adsorbents enable magnetic separation for removal of heavy metals, radionuclides, or organic pollutants in wastewater. In addition, the removal of other pollutants such as phosphate and pathogen as well as detection of endocrine disruptors are also highlighted. Finally, the new research perspectives and directions are recommended, such as efficient isolation, genetic modification of MTB for mass production and novel environmental applications.
