Calculations of magnetic susceptibility of magnetotactic bacteria (MTB) cul
ture are reported. The model was elaborated with regard to the effect of ch
emotaxis for two different geometrical compositions of the experiment. The
results obtained allow one to determine concentration of MTB from magnetic
measurements. It was shown that the characteristic parameters of chemotaxis
can be extracted from the dependencies of the susceptibility on magnetic f
ield strength. (C) 2001 Elsevier Science B.V. All rights reserved.
