[Effect of dispersion of electric parameters of bacterial cells on their orientation in alternating electric fields]

On the basis of electrophysical model of bacterial cell frequency relationship of orienting force moment acting on it in the alternating electric field has been calculated. Dependence of relative value of the moment on electric and geometrical parameters of the model was calculated. It has been shown that the account of frequency dispersion of the electric parameters brings about a change in the course of frequency relationship of the orienting moment in the range of low and mean frequencies. The data obtained agree with electrooptic measurements performed on E. coli cells.
