Do ferrous iron-oxidizing acidophiles (Leptospirillum spp.) disturb aerobic bioleaching of laterite ores by sulfur-oxidizing acidophiles (Acidithiobacillus spp.)? [PDF]
Frontiers in MicrobiologyThe extraction of nickel, cobalt, and other metals from laterite ores via bioleaching with sulfur-oxidizing and ferric iron-reducing, autotrophic, acidophilic bacteria (e.g.

Goethite dissolution by acidophilic bacteria. [PDF]
Front MicrobiolPrevious 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.

Biotechnologies that Utilise Acidophiles [PDF]
Current Issues in Molecular Biology, 2016 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.

Frontiers in Microbiology, 2022 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 ...

Frontiers in Microbiology, 2022 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
Microorganisms, 2020 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.

Frontiers in Microbiology, 2022 In acid drainage environments, biosulfidogenesis by sulfate-reducing bacteria (SRB) attenuates the extreme conditions by enabling the precipitation of metals as their sulfides, and the neutralization of acidity through proton consumption.

Microorganisms, 2023 Bioleaching processes or microbially mediated iron/sulfur redox processes in acid mine drainage (AMD) result in mineral dissolution and transformation, the release of mercury and other heavy metal ions, and changes in the occurrence forms and ...

Frontiers in Microbiology, 2014 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
