pH sensing refers to the molecular mechanisms by which bacteria detect and respond to changes in environmental acidity. In the gut — where pH ranges from ~2 in the stomach to ~7.4 in the distal ileum and ~5.5-7.0 in the colon — pH is a master regulator of metal bioavail…
Quorum sensing (QS) is cell-density-dependent communication in which bacteria produce, secrete, and detect small signaling molecules (autoinducers) to coordinate group behaviors — including biofilm formation, virulence factor production, siderophore synthesis, and antib…
