Magnetotactic bacteria are a class of bacteria that has nano sized magnetic crystals inside their body and respond to geomagnetic field. This paper reports the experimental research on visualization of magnetotactic bacteria "Magnetospirillum Magnetotacticum" behaviors under no/DC/AC magnetic field. The motion of magnetotactic bacteria was observed using an optical dark-field microscope system. The images were taken using cameras, and measured by image processing techniques. Applying DC/AC magnetic field, it was observed that magnetotactic bacteria rotated in the direction of magnetic field.
