This minireview presents recent advances in our understanding of iron oxidation and
homeostasis in acidophilic Bacteria and Archaea. These processes influence the flux of …

Extremely acidophilic microorganisms have an optimal pH of< 3 and are found in all three
domains of life. As metals are more soluble at acid pH, acidophiles are often challenged by …

Mining-industry is one of the most important activities in the economic development of many
countries and produces highly significant alterations on the environment, mainly due to the …

High concentrations of chloride ions inhibit the growth of acidophilic microorganisms used in
biomining, a problem particularly relevant to Western Australian and Chilean biomining …

Zinc can occur in extremely high concentrations in acidic, heavy metal polluted
environments inhabited by acidophilic prokaryotes. Although these organisms are able to …

In acidophilic microorganisms, anions like chloride have higher toxicity than their
neutrophilic counterparts. In addition to the osmotic imbalance, chloride can also induce …

Extremely acidophilic microorganisms (pH optima for growth of≤ 3) are utilized for the
extraction of metals from sulfide minerals in the industrial biotechnology of “biomining.” A …

Siderophores are iron-chelating molecules produced by microbes when intracellular iron
concentrations are low. Low iron triggers a cascade of gene activation, allowing the cell to …

The extremely thermoacidophilic archaeon Metallosphaera sedula mobilizes metals by
novel membrane-associated oxidase clusters and, consequently, requires metal resistance …

About 10 years ago, a new family of cell wall-deficient, iron-oxidizing archaea,
Ferroplasmaceae, within the large archaeal phylum Euryarchaeota, was described. In this …
