The concentrations of U in natural waters are usually low, being typically less than 4 μg/L in
river water, around 3.3 μg/L in open seawater, and usually less than 5 μg/L in groundwater …

Uranium (U) is of enormous global importance because of its use in energy generation,
albeit with potential environmental legacies. While naturally occurring U is widespread in the …

The subterranean world hosts up to one-fifth of all biomass, including microbial communities
that drive transformations central to Earth's biogeochemical cycles. However, little is known …

A prominent feature of the bacterial domain is a radiation of major lineages that are defined
as candidate phyla because they lack isolated representatives. Bacteria from these phyla …

Discerning network interactions among different species/populations in microbial
communities has evoked substantial interests in recent years, but little information is …

Background Sediments are massive reservoirs of carbon compounds and host a large
fraction of microbial life. Microorganisms within terrestrial aquifer sediments control buried …

Microbial metabolism has the potential to alter the solubility of a broad range of priority
radionuclides, including uranium, other actinides and fission products. Of notable interest …

Bacteria from phyla lacking cultivated representatives are widespread in natural systems
and some have very small genomes. Here we test the hypothesis that these cells are small …

BD1-5, OP11, and OD1 bacteria have been widely detected in anaerobic environments, but
their metabolisms remain unclear owing to lack of cultivated representatives and minimal …

Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …
