Growing <i>Magnetospirillum</i> Bacteria and Assessing Their Magnetotactic Behavior

Source: Le Nagard, L., et al. Growing Magnetotactic Bacteria of the Genus Magnetospirillum: Strains MSR-1, AMB-1 and MS-1. J. Vis. Exp. (2018).This video demonstrates how to culture Magnetospirillum bacteria under microaerobic conditions using both liquid and semi-solid media. It highlights the formation of a visible bacterial band at the oxic-anoxic interface and its upward migration as oxygen is depleted. The video also shows how to assess magnetotactic behavior by observing directional swimming in response to a magnetic field.
