ResumoThe zeta potential of Saccharomyces cerevisiae cells has been studied. Zeta potential was measured by microelectrophoresis with a Laser Zee meter model 500. Haploid (a and α) and diploid cells were tested and their zeta potential was found to be comparable. The influence of agents such as CaCl2, NaCl, carboxymethylcellulose, Al2(SO4)3 and cationic starch, on the zeta potential of cells has been studied. Moreover, zeta potential measurement has been used for improvement of cell immobilization by adhesion on sawdust.
