Figure 2

Effect of shear rate, pH and inorganic salts on the viscosity of the crude EPS solution of strain SM1127.

Viscosity was measured by using a Brookfield viscometer with spindle S16. (a) The effect of different shear rates on the viscosity of the EPS solutions at different concentrations (0.5%, 0.8%, 1.0%, 1.2%, 1.5% and 2.0% [w/v]). (b) The effect of pH (1–14) on the viscosity of 1.5% (w/v) EPS solution (25 °C). (c) The effect of different concentrations of NaCl and CaCl2 (0–10%) on the viscosity of 1.5% (w/v) EPS solution (25 °C). The graph shows data from triplicate experiments (mean ± S.D.).
