Birefringence determination of magnetic moments of magnetotactic bacteria.
A birefringence technique is used to determine the average magnetic moments <mu> of magnetotactic bacteria in culture. Differences in <mu> are noted between live and dead bacteria, as well as between normal density and high density samples of live bacteria.
