Biotechnologies that Utilise Acidophiles [PDF]
The bioleaching of mineral sulfides provides the most prevalent anthropogenic application of chemolithotrophic acidophiles. The same reactions, occurring unconstrained in the environment, are also the cause of acid mine drainage (AMD), a major issue with respect to water pollution.

Metal resistance or tolerance? Acidophiles confront high metal loads via both abiotic and biotic mechanisms [PDF]
All metals are toxic at high concentrations and consequently their intracellular concentrations must be regulated. Acidophilic microorganisms have an optimum growth pH < 3 and proliferate in natural and anthropogenic low pH environments. Some acidophiles

Bioprospecting for and the applications of halophilic acidophiles in bioleaching operations [PDF]
The economic recovery of metals from sulfide ores has become a topic of increasing interest due to the escalating demand for critical minerals and the reducing grade of available ores.

Goethite dissolution by acidophilic bacteria. [PDF]
Previous studies have reported the role of some species of acidophilic bacteria in accelerating the dissolution of goethite under aerobic and anaerobic conditions. This has relevance for environments impacted by acid mine drainage and for the potential bioleaching of limonitic laterite ores.

Comparative genomics of the proteostasis network in extreme acidophiles. [PDF]
Extreme acidophiles thrive in harsh environments characterized by acidic pH, high concentrations of dissolved metals and high osmolarity. Most of these microorganisms are chemolithoautotrophs that obtain energy from low redox potential sources, such as ...

The genome streamlining theory suggests that reduction of microbial genome size optimizes energy utilization in stressful environments. Although this hypothesis has been explored in several cases of low-nutrient (oligotrophic) and high-temperature ...

Extreme acidophiles thrive in environments rich in protons (pH values <3) and often high levels of dissolved heavy metals. They are distributed across the three domains of the Tree of Life including members of the Proteobacteria. The Acidithiobacillia

Biosulfidogenesis Mediates Natural Attenuation in Acidic Mine Pit Lakes
Acidic pit lakes are abandoned open pit mines filled with acid mine drainage (AMD)—highly acidic, metalliferous waters that pose a severe threat to the environment and are rarely properly remediated.
