Biodiversity and ecology of acidophilic microorganisms [PDF]
FEMS Microbiology Ecology, 1998 Microbial life in extremely low pH (6 3) natural and man-made environments may be considerably diverse. Prokaryotic acidophiles (eubacteria and archaea) have been the focus of much of the research activity in this area, primarily because of the importance of these microorganisms in biotechnology (predominantly the commercial biological processing of ...

Minerals Engineering, 2019 Bioleaching is an efficient environmentally safe process for extracting metals from ore and waste sludge. In the bioleaching/biohydrometallurgical process, mainly chemolithotrophic microorganisms convert insoluble metal sulphides or oxides (directly or ...

Iron Meteorites Can Support the Growth of Acidophilic Chemolithoautotrophic Microorganisms [PDF]
Astrobiology, 2005 Chemolithoautotrophy based on reduced inorganic minerals is considered a primitive energy transduction system. Evidence that a high number of meteorites crashed into the planet during the early period of Earth history led us to test the ability of iron-oxidizing bacteria to grow using iron meteorites as their source of energy. Here we report the growth

Fossilization of Acidophilic Microorganisms
Geomicrobiology Journal, 2010This study examines fossil microorganisms found in iron-rich deposits in an extreme acidic environment, the Tinto River in SW Spain. Both electron microscopy (SEM and TEM) and non-destructive in situ microanalytical techniques (EDS, EMP and XPS) were used to determine the role of permineralization and encrustation in preserving microorganisms forming ...

Acidophilic microorganisms in remediation of contaminants present in extremely acidic conditions
Bioprocess and Biosystems Engineering, 2023Acidophiles are a group of microorganisms that thrive in acidic environments where pH level is far below the neutral value 7.0. They belong to a larger family called extremophiles, which is a group that thrives in various extreme environmental conditions which are normally inhospitable to other organisms.

Coal desulfurization by leaching involving acidophilic and thermophilic microorganisms [PDF]
Biotechnology and Bioengineering, 1982 It was shown that thermophilic microorganisms can increase the rate and volume of pyrite leaching from pulverized, high-sulfur coal. This occurs not only because of the elevated temperature of operation possible, but also the apparent accelerated catalytic activity of thermophilic microorganisms as compared to autotropic microbes such as T ...
