Comments "The purpose of the experiments reported in this communication was to obtain a measure of the magnitude of the protonmotive force that is developed across the cytoplasmic membrane of respiring Staphylococcus aureus and Escherichia coli." "Table 2 shows averaged values of ?pH?, ???, and ?p? for six determinations with each organism. In each case, the initial external pH was adjusted so that the pHo?, the external pH under energized conditions, was near to 6.5 (approximately the pH of the medium from which the cells were harvested). The values of ?p were 211±15mV for S. aureus and 230±15mV for E. coli." See notes beneath table.
