Microbial sulfate reduction in the oxic sediments of sulfide ore mine tailings
Mining of metallic ore deposits produce large volumes of various wastes containing metal sulfides. When the sulfides are exposed to oxygenated water, they oxidized and produced acid water laden with sulfate, metal and metalloids more...

 Microbial diversity in the deep subsurface resevoir
The deep subsurface biosphere is considered to be a “seed bank” of thermophilic microorganisms. We study microbial diversity in the outflow of a deep (2600 m), artesian, thermal, oil-exploration borehole in Western Siberia more...

Resistance to copper in SRB
Sulfate-reducing prokaryotes (SRP) is a phylogenetically and physiologically diverse group of prokaryotes that can gain energy from dissimilatory reduction of sulfate. Microbial sulfate reduction is instrumental in copper as well as other metal precipitation and various technological schemes have been developed currently. The molecular mechanisms of copper homeostasis and trafficking are yet to be elucidated in this guild of prokaryotes more...
 
The geochemical importance of dissimilatory sulfate reduction in the formation of diagenetic iron sulfides in sedimentary environments is generally accepted. The environmentally important sulfate-reducing prokaryotes (SRP) are also recognized to be normal constituents of gut microbiota in humans and animals more...
