A Birefringence Relaxation Determination of Rotational Diffusion of Magnetotactic Bacteria

Charles Rosenblatt, Richard B Frankel, Richard P Blakemore
PMCID: PMC1435214  PMID: 19431585

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 Dr [unk] 0.13 s-1 and information about cell sizes that is consistent with optical microscopy data.
