Escherichia coli K12 becomes resistant to killing by acid (habituates to acid) in a few minutes at pH 5.0. Habituation involves protein synthesis-dependent and -independent stages; both must occur at an habituating pH. The habituation sensor does not detect increased delta pH (or decreased delta psi) nor an increased difference between pHo and periplasmic pH but probably detects a fall in either external or periplasmic pH. Phosphate ions inhibit habituation, at any stage, probably by… CONTINUE READING
