Abstract:
Buffering capacity and membrane H + conductance were examined in three gram-positive bacteria, Staphylococcus aureus , Bacillus subtilis , and Bacillus alcalophilus . An acid pulse technique was used to measure both parameters. The buffering capacity and membrane H + conductance of B. alcalophilus are influenced by the pH of the medium and the culture conditions. Suspensions of B. alcalophilus cells from both H. A. medium and l -malate medium cultures grown at pH 10.5 exhibited higher values for these parameters than cells grown at pH 8.5. B. alcalophilus grown aerobically had a lower buffering capacity and a lower membrane conductance for protons than the neutrophilic bacteria S. aureus and B. subtilis . Fermenting cells exhibited significantly higher values for both variables than respiring cells.
