Configuration of redox gradient determines magnetotactic polarity of the marine bacteria MO‐1
Summary Magnetotactic bacteria are capable of aligning and swimming along the geomagnetic field lines; such a behaviour is called magnetotaxis. Previous studies reported that bacteria in the northern hemisphere migrate preferentially towards the North Pole of the Earth's magnetic field (north‐s...
