An Adaptation To Life In Acid Through A Novel Mevalonate Pathway [PDF]
, 2016 Extreme acidophiles are capable of growth at pH values near zero. Sustaining life in acidic environments requires extensive adaptations of membranes, proton pumps, and DNA repair mechanisms.

Function and Adaptation of Acidophiles in Natural and Applied Communities [Elektronisk resurs]
, 2018 Acidophiles are organisms that have evolved to grow optimally at high concentrations of protons. Members of this group are found in all three domains of life, although most of them belong to the Archaea and Bacteria.

Growth in sulfidic mineral environments: metal resistance mechanisms in acidophilic micro-organisms
, 2003 Acidophilic micro-organisms inhabit some of the most metal-rich environments known, including both natural and man-made ecosystems, and as such are ideal model systems for study of microbial metal resistance.
