Early diagenetic vivianite [Fe-3(PO4)(2) center dot 8H(2)O] in a contaminated freshwater sediment and insights into zinc uptake: a mu-EXAFS, mu-XANES and Raman study [PDF]
The sediments in the Salford Quays, a heavily-modified urban water body, contain high levels of organic matter, Fe, Zn and nutrients as a result of past contaminant inputs.

Sulfur microenvironments as hotspots for biogenic pyrite formation
Pyrite (FeS2) is the end-product of bacterial sulfur cycling in reduced sedimentary environments. Sulfate-reducing bacteria (SRB) are mostly considered for biogenic pyrite formation due to their significant contribution to sulfide production at ambient ...

The Impact of Host Rock Geochemistry on Bacterial Community Structure in Oligotrophic Cave Environments. [PDF]
Despite extremely starved conditions, caves contain surprisingly diverse microbial communities. Our research is geared toward understanding what ecosystems drivers are responsible for this high diversity. To asses the effect of rock fabric and mineralogy,

Interrelationship of hydrology, microbial colonisation and hydrometallurgy in a simulated chalcopyrite heap leach [PDF]
Includes bibliographical references (leaves 104-115).Chalcopyrite is the most abundant primary copper sulphide mineral found worldwide. As copper grades of ores available for extraction decrease, heap bioleaching is gaining interest as a potential ...

Unveiling plasmid diversity and functionality in pristine groundwater
Background Plasmids are key in creating a dynamic reservoir of genetic diversity, yet their impact on Earth’s continental subsurface—an important microbial reservoir—remains unresolved. We analyzed 32 metagenomic samples from six groundwater wells within

Microbially Mediated Ore-Forming Processes and Cell Mineralization
Sedimentary black shale-hosted manganese carbonate and oxide ores were studied by high-resolution in situ detailed optical and cathodoluminescence microscopy, Raman spectroscopy, and FTIR spectroscopy to determine microbial contribution in metallogenesis.

Diversity and biosynthetic potential of culturable aerobic heterotrophic bacteria isolated from Magura Cave, Bulgaria [PDF]
Biocapacity of bacteria inhabiting karstic caves to produce valuable biologically active compounds is still slightly investigated. A total of 46 culturable heterotrophic bacteria were isolated under aerobic conditions from the Gallery with pre-historical
