Abstract The dielectrophoretic yield of cell suspensions of Saccharomyces cerevisiae shows a maximum for a given frequency and this maximum shifts towards higher frequencies as the electrical conductivity of the medium increases. The addition of cations to cell suspensions of S. cerevisiae, maintaining the electric conductivity constant, leads to a decrease in the dielectrophoretic yield, depending of the valence of the cations added. Both results could be interpreted by a modified Maxwell-Wagner mechanism. Cetrimide is the most efficient detergent in permeabilizing yeast cells and the dielectrophoretic yield could be used as a method for quantifying cellular viability.
