Induction of acid sensitivity occurred rapidly at both 37 and 30 degrees C, with a substantial effect within 15 min. Sensitization was partially inhibited by chloramphenicol and tetracycline and may depend on both protein synthesis-dependent and -independent physiological changes in the NaCl-induced organisms; sensitization did not result from osmotic shocking on transfer to challenge medium. Induction of acid sensitivity was affected by neither the sodium ion pore inhibitor amiloride nor the DNA synthesis inhibitor nalidixic acid; rifampin had a small effect, similar to that of chloramphenicol. Chlorides of other monovalent cations, especially Li+ and NH4+, also produced sensitization to acid, although CsCl was ineffective but did not interfere with sensitization by NaCl. Other sodium salts were also active as sensitizers, as were chlorides of divalent cations, but although sucrose (but not glycerol) was a good inducer, the results were not fully in accord with triggering of induction solely by the NaCl-associated increase in osmotic pressure. Sensitization was not prevented by deletion of the nhaA, nhaR, or nhaB gene. Acid sensitivity of NaCl-induced cells was slightly reduced after 90 min of growth at 37 degrees C in low-salt broth but was completely lost after 240 min. For NaCl-induced cells, acid killing in challenge media was not inhibited by amiloride. The NaCl-induced sensitization is distinct from the phenomenon of acid sensitivity induction in E. coli at alkaline external pH."xsd:string |
