Magnetotactic bacteria (MTB) arewidespreadaquaticprokaryotes.They navigate along magnetic field pathways through magnetosomes, which are membrane-bound intracellular structures containing iron-based magnetic crystals. The process of MTB isolation requires a container to collect sediment and water from natural environments like a freshwater pond. MTB possess crucial magnetic characteristics that are exploited in various areas, including MRI diagnostics, magnetic hyperthermia, targeted drug delivery, and additional medical applications. Environmentally, they assist in wastewater treatment by eliminating radionuclides, organic contaminants, and heavy metals. Furthermore, the extensive surface area of their magnetic particles enhances adsorption of organic pollutants such as organophosphate pesticides. This study provides a concise review of MTB, covering their morphology and selected biotechnological applications.
