Abstract
The intracellular C1 concentration in Escherichia coli has been studied as a function of the Cl concentration in the growth medium and the age of the bacterial culture. The ratio of extracellular to intracellular Cl concentration is shown to be 3.0 in the logarithmic phase and 1.13 in the stationary phase (both ratios being independent of the extracellular Cl concentration). If it may be assumed that Cl is passively distributed in this organism; these results are consistent with a transmembrane P.D. of 29 mv, interior negative, during the logarithmic phase, and 3 mv, interior negative, in the stationary phase.
