The N,N'-dicyclohexylcarbodiimide sensitive exchange of 2H+ of a cell for K+ of medium stable to pH, K+ activity and temperature changes has been discovered in anaerobically grown gram-negative Escherichia coli, Salmonella typhimurium. S. enteritidis, Proteus mirabilis, P. vulgaris, anaerobic gram-positive bacteria Streptococcus faecalis, Lactobacillus salivarius, L. lactis in the presence of exogenic energy source. This exchange in gram-negative bacteria is operating only at increase of medium osmolarity. The high K+ distribution between cell and medium has been reached during the exchange of 2H+ for one K+ and the corresponding potassium equilibrium potential is much more than the measured delta psi. In aerobically grown E. coli, S. typhimurium, Brevibacterium flavum and aerobic Micrococcus luteus exchange of 2H+ for K+ does not take place, the K+ distribution is lower and in good conformity with the measured delta psi. It is assumed that exchange of 2H+ for K+ in anaerobic bacteria is carried out by the H+-ATPase complex and the Trk (or Trk-like) system of K+ absorption united into the same membrane supercomplex which functions as the H+-K+-pump and supports the high K+ distribution between cell and medium.
