Microbes from the three domains of life, Bacteria, Archaea, and Eukarya, share the need to
sense and respond to changes in the external and internal concentrations of protons. When …

Microorganisms encounter acid stress during multiple bioprocesses. Microbial species have
therefore developed a variety of resistance mechanisms. The damage caused by acidic …

Bacteria and archaea occupy a considerable diversity of niches that vary with respect to the
