Bacterial Leaching of Metal Sulfides Proceeds by Two Indirect Mechanisms via Thiosulfate or via Polysulfides and Sulfur
ABSTRACT The acid-insoluble metal sulfides FeS2, MoS2, and WS2 are chemically attacked by iron(III) hexahydrate ions, generating thiosulfate, which is oxidized to sulfuric acid. Other metal sulfides… Expand

Prokaryotic cells of the deep sub-seafloor biosphere identified as living bacteria
Chemical analyses of the pore waters from hundreds of deep ocean sediment cores have over decades provided evidence for ongoing processes that require biological catalysis by prokaryotes. This… Expand

Distributions of Microbial Activities in Deep Subseafloor Sediments
Diverse microbial communities and numerous energy-yielding activities occur in deeply buried sediments of the eastern Pacific Ocean. Distributions of metabolic activities often deviate from the… Expand

MICROORGANISMS INVOLVED IN BIOLEACHING AND NUCLEIC ACID-BASED MOLECULAR METHODS FOR THEIR IDENTIFICATION AND QUANTIFICATION
Bioleaching is the biological conversion of an insoluble metal compound into a water soluble form. In case of metal sulfide bioleaching, metal sulfides are oxidized to metal ions and sulfate by… Expand

Aerobic and anaerobic methanotrophs in the Black Sea water column.
Inputs of CH(4) from sediments, including methane seeps on the continental margin and methane-rich mud volcanoes on the abyssal plain, make the Black Sea the world's largest surface water reservoir… Expand

Quantification of microbial communities in near-surface and deeply buried marine sediments on the Peru continental margin using real-time PCR.
Deeply buried marine sediments harbour a large fraction of all prokaryotes on Earth but it is still unknown which phylogenetic and physiological microbial groups dominate the deep biosphere. In this… Expand

Subsurface microbiology and biogeochemistry of a deep, cold-water carbonate mound from the Porcupine Seabight (IODP Expedition 307)
The Porcupine Seabight Challenger Mound is the first carbonate mound to be drilled (∼270 m) and analyzed in detail microbiologically and biogeochemically. Two mound sites and a non-mound Reference… Expand

Coalbed methane in the Ruhr Basin, Germany: a renewable energy resource?
Around the globe underground hard coal mining leads to a release of methane into the atmosphere. About 7% of the global annual methane emissions originate from coal mining. In the year 2002, 16… Expand

Subseafloor microbial communities associated with rapid turbidite deposition in the Gulf of Mexico continental slope (IODP Expedition 308).
The subseafloor microbial communities in the turbidite depositional basins Brazos-Trinity Basin IV (BT Basin) and the Mars-Ursa Basin (Ursa Basin) on the Gulf of Mexico continental slope (IODP holes… Expand
