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.
