Chapter 5 Regulation of cytoplasmic pH in bacteria

Intracellular pH (pHi) is the measure of the acidity or basicity (i.e., pH) of intracellular fluid. The pHi plays a critical role in membrane transport and other intracellular processes. In an environment with the improper pHi, biological cells may have compromised function. Therefore, pHi is closely regulated in order to ensure proper cellular function, controlled cell growth, and normal cellular pro… WebInternal cytoplasmic pH can be estimated from the optimal pH of intracellular enzymes. For example, α-galactosidase from an alkaliphile, Micrococcus sp. strain 31-2, had its optimal catalytic pH at 7.5, suggesting that the internal pH is around neutral.
