A birefringence relaxation determination of rotational diffusion of magnetotactic bacteria.

C Rosenblatt, R B Frankel, R P Blakemore.

Abstract

The orientational relaxation of the magnetotactic bacterium Aquaspirillum magnetotacticum is observed by the decay of the optical birefringence upon switching off an aligning magnetic field. The data yield a rotational diffusion constant D(r) [unk] 0.13 s(-1) and information about cell sizes that is consistent with optical microscopy data.
