title: Cytoplasmic pH homeostasis in an acidophilic bacterium, Thiobacillus acidophilus.
abstract: The cytoplasmic buffering capacity of Thiobacillus acidophilus (along with membrane properties) is responsible for the cytoplasmic pH homeostasis in metabolically compromised cells. When a large influx of H+ occurs, the cytoplasmic buffering capacity prevents drastic changes in pH; in addition, this influx, by increasing the positive membrane potential, eventually leads to a cessation of further H+ influx.
