Abstract in another language

Magnetospirillum gryphiswaldense is a magnetotactic bacterium with a permanent magnetic moment
capable of swimming using two bipolarly located flagella. In their natural environment these bacteria
swim along the field lines of the homogeneous geomagnetic field in a typical run and reversal pattern
and thereby create non-differentiable trajectories with sharp edges. In the current work we nevertheless
achieve stable guidance along curved lines of mechanical instability by using a heterogeneous magnetic
field of a garnet film. The successful guidance of the bacteria depends on the right balance between
motility and the magnetic moment of the magnetosome chain.
