Abstract
The deformability of a bacterial wall of the gram-negative bacterium Magnetospirillum gryphiswaldense is investigated with an atomic force microscopy (AFM). A theoretical expression is derived for the force exerted by the wall on the cantilever as a function of the depths of indentation generated by the AFM tip. This reaction force is a measure for the turgor pressure of the bacterium. Results determined the turgor pressure to be in the range of 85 to 150 kPa.
