Comments "The intracellular Cl concentrations of cells harvested in the logarithmic and late stationary phases of growth, in the presence of 25, 50, 75, and 100 mM Cl are summarized in Table II and Fig. 1 (the subscripts i and o denote the intracellular and extracellular compartments respectively). The ratios of the intracellular to extracellular concentrations of Na and K, during the logarithmic and late stationary phases are also given in Table II. The Na ratios are in good agreement with those found previously in this laboratory using a somewhat different growth medium and in the presence of lower extracellular Na concentrations (ref 3). Furthermore, the average intracellular K concentration during the logarithmic phase of growth of 231 mM agrees well with the figure of 222 mM reported previously (ref 3). These results indicate that the presence of Cl in the growth medium in varying concentrations does not affect the steady-state distribution of Na or K in this organism." See notes beneath table
