Magnetospirillum is a Gram-negative, microaerophilic genus of magnetotactic bacteria, first isolated from pond water by the microbiologist R. P. Blakemore in 1975. They have a spiral (helical) shape and are propelled by a polar flagellum at each end of their cells. The three main species identified are M. magnetotacticum strain MS-1, M. griphiswaldense strain MSR-1, and M. magneticum strain AMB-1.

==Habitat== The first discovered magnetotactic bacteria came from various environments including seawater, lakes, ponds, silt and soils in 1975 – including Magnetospirillum. The typical habitat of Magnetospirillum species consists of shallow fresh water and sediments, characterized by low concentrations of oxygen for growth (microaerophilic) where they live in the upper portion of the sediment (oxic/anoxic interface) and prefer an oxygen gradient of around 1–3%.
