Abstract excerpt
The acid tolerance response (ATR) is an adaptive system triggered at external pH (pHo) values of 5.5 to 6.0 that will protect cells from more severe acid stress (J. Foster and H. Hall, J. Bacteriol. 172:771-778, 1990). Correlations between the internal pH (pHi) of adapted versus unadapted cells at pHo of 3.3 indicate that the ATR system produces an inducible pH-homeostatic function. This function serves to...
