Webb1 okt. 1979 · The large effect of CCCP in the pH range 6.5–7.5 strongly suggests that the survival after hyperthermia is mainly determined by the cytoplasm pH. Changes in the pH of the cell medium may affect survival only after modifying the cytoplasm pH. In the pH range 6.5–8.0 the cells are apparently able to maintain the optimal pH value inside, close to 8.0. Webb25 feb. 2024 · Per previous findings, the wild-type cells maintain their cytoplasmic pH within a range of pH 7.4–7.7 over an external pH range of 6.0–8.1 (13-15). We find here that, under the same conditions, the resistant strain displays a substantially more acidic pHibetween 7.1-7.5. We identified here one pathway involved in the reported acidification.
