ABSTRACT
A method was developed for the measurement of the bacterial particle conductivity, based on the measurement of the conductivity of a bacterial cell suspension sigma(s) and the suspending medium sigma(m). A line plotted through sigma(s) - sigma(m) versus sigma(m) crosses the x-axis at sigma(m) = sigma(p), independent of the bacterial cell concentration. The method does not require anything more complex than a centrifuge and a conductivity meter. Knowledge of the bacterial particle conductivity is of importance in, for example, the dielectrophoretic separation, manipulation and trapping of bacterial cells, as well as the study of their physiological state.
