Evidence for an internal electrochemical proton gradient in Methanobacterium thermoautotrophicum

At pH > 7.5 cells of Methanobacterium thermoautotrophicum , when synthesizing CH sub(4) from CO sub(2) and H sub(2), are interior acid with respect to the buffer. If the buffer pH is lowered below pH 6.5 with HCl, the pH gradient has the usual orientation, i.e. the cells become interior alkaline....
