Extremophiles comprise microorganisms that are able to grow and thrive in extreme
environments, including in an acidic or alkaline pH, high or low temperatures, high …

Diverse mechanisms for pH sensing and cytoplasmic pH homeostasis enable most bacteria
to tolerate or grow at external pH values that are outside the cytoplasmic pH range they must …

Extremely acidic, sulfur‐rich environments can be natural, such as solfatara fields in
geothermal and volcanic areas, or anthropogenic, such as acid mine drainage waters. Many …

The widely distributed Acidithiobacillus ferrooxidans (A. ferrooxidans) lives in extremely
acidic conditions by fixing CO 2 and nitrogen, and by obtaining energy from Fe 2+ oxidation …

The anthropogenic activities in agriculture, industrialization, mining, and metallurgy
combined with the natural weathering of rocks, have led to severe contamination of soils by …

Protecting the environment from harmful pollutants has become increasingly difficult in
recent decades. The presence of heavy metal (HM) pollution poses a serious environmental …

Gene transcription (microarrays) and protein levels (proteomics) were compared in cultures
of the acidophilic chemolithotroph Acidithiobacillus ferrooxidans grown on elemental sulfur …

Industrial biomining processes to extract copper, gold and other metals involve the use of
extremophiles such as the acidophilic Acidithiobacillus ferrooxidans (Bacteria), and the …

Microbial solubilizing of metals in acid environments is successfully used in industrial
bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others …

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 …
