In vitro Exo1 mediated Na+ sequestration. Bars show the amounts of bioadsorped Na+ in mg kg−1 dry weight of purified EPS, which was incubated overnight at 4°C in solutions containing 5, 15 and 20% NaCl (w/v). EPS without salt treatment (0% NaCl) was used as control. Error bars represent mean ± standard deviation of triplicate values.
