Electrophoretic mobilities and zeta potentials of E. coli D21g cells harvested at 3 and 18 h (corresponding to mid-exponential- and stationary-phase cells) as a function of ionic strength (KCl). Experiments were conducted at ambient pH (5.6 to 5.8) and temperature (25°C). Error bars indicate 1 standard deviation.
