Bioleaching acidophiles inhabit environments with unusually high concentrations of iron that can potentially cause oxidative stress via the Fenton reaction in which dangerous reactive oxygen species (ROS) are generated. ...

By March 2015, 161 genomes of acidophilic microorganisms had been published, including 126 permanent draft and closed genomes and 35 partial genomes reconstructed from metagenomic data, distributed between Archaea (71), ...

Acidophilic archaea thrive in anaerobic and aerobic low pH environments (pH < 5) rich in dissolved heavy metals that exacerbate stress caused by the production of reactive oxygen species (ROS) such as hydrogen peroxide (H2 ...

© 2018, © 2018 Taylor & Francis Group, LLC. The genome of the acidophilic, bioleaching bacterium Acidithiobacillus ferrooxidans, strain ATCC 23270, contains 95 predicted tRNA genes. Thirty-six of these genes (all 20 species) ...

The major industrial heap bioleaching processes are located in desert regions (mainly Chile and Australia) where fresh water is scarce and the use of resources with low water activity becomes an attractive alternative. ...

The study of extreme acidophiles, broadly defined as microorganisms that grow optimally at pH values below 3, was initiated by the discovery by Waksman and Joffe in the early 1900s of a bacterium that was able to live ...
