This paper describes the electrokinetic, adsorption and stability properties of the silica–exopolysac-charide Sinorhizobium meliloti (EPS). Exopolysaccharide adsorbs on the silica surface in the whole pHrange, but the adsorption amount increases with the pH growth (at pH 9 approx. 0.8 mg/m2). The EPSadsorption affects the electrokinetic and stability properties of the system. At low pH values (3 and 4.6)the increase in the system stability occurs (electrosteric interactions), whereas at higher (7.6 and 9) thelight system destabilization was noted (formation of a single polymer bridges between particles).
