[Sources of convertible energy in Staphylococcus]

It has been found out that Staphylococcal cells have two basic convertible energy sources--the intercell ATP pull and electrochemical potential of hydrogen ions. The ATP synthesis takes place under laying the membrane potential by creation of K+ gradient in valinomycin presence and in the transmembrane gradient pH. The magnitude of the transmembrane electrical potential difference was determined and it reached from 100 to 160 mV within pH range of 5.0-8.0 at the same time pH dropped from 90 to 40 mV. The protonmotive force magnitude remains invariable (191-198 mV) at the pH range 5.0-8.0.
