▪ Abstract The use of acidiphilic, chemolithotrophic iron-and sulfur-oxidizing microbes in
processes to recover metals from certain types of copper, uranium, and gold-bearing …

Phototrophic sulfur bacteria are characterized by oxidizing various inorganic sulfur
compounds for use as electron donors in carbon dioxide fixation during anoxygenic …

Introduction to Geomicrobiology is a timely and comprehensive overview of how microbial
life has affected Earth's environment through time. It shows how the ubiquity of …

In the case of pyrite bioleaching by Leptospirillum ferrooxidans, an organism without sulfur-
oxidizing capacity, besides the production of tetra-and pentathionate, a considerable …

The dissolution of metal sulfides is controlled by their solubility product and thus, the [H+]
concentration of the solution, and further enhanced by several chemical mechanisms which …

Background A variety of chemoautolithotrophic bacteria which are capable of oxidizing iron-
or sulphur-containing minerals may be readily isolated from acidic mine drainage or places …

Future sustainable development requires measures to reduce the dependence on
nonrenewable raw materials and the demand for primary resources. New resources for …

We investigated the potential role of the three strains of Thiobacillus caldus (KU, BC13, and
C-SH12) in arsenopyrite leaching in combination with a moderately thermophilic iron …

Résumé Prokaryotes have been shaping the surface of the Earth and impacting
geochemical cycles for the past four billion years. Biomineralization, the capacity to form …

The bioleaching of sulfide minerals involves electrochemical and chemical reactions of the
mineral with the leach liquor and the extra-cellular polysaccharide layers on the …
