Phylogenetic surveys of soil ecosystems have shown that the number of prokaryotic species
found in a single sample exceeds that of known cultured prokaryotes. Soil metagenomics …

Archaea represent a considerable fraction of the prokaryotic world in marine and terrestrial
ecosystems, indicating that organisms from this domain might have a large impact on global …

Metagenomics is the study of the genomic content of a sample of organisms obtained from a
common habitat using targeted or random sequencing. Goals include understanding the …

For years, microbiologists characterized the Archaea as obligate extremophiles that thrive in
environments too harsh for other organisms. The limited physiological diversity among …

The species complexity of microbial communities and challenges in culturing representative
isolates make it difficult to obtain assembled genomes. Here we characterize and compare …

Mesophilic crenarchaeota are frequently found in terrestrial and marine habitats worldwide,
but despite their considerable abundance the physiology of these as yet uncultivated …

Background Soil ecosystems harbor the most complex prokaryotic and eukaryotic microbial
communities on Earth. Experimental approaches studying these systems usually focus on …

Nitrification is a microbially mediated process that plays a central role in the global cycling of
nitrogen and is also of economic importance in agriculture and wastewater treatment. The …

Crenarchaeota are ubiquitous and abundant microbial constituents of soils, sediments,
lakes, and ocean waters. To further describe the cosmopolitan nonthermophilic …

Metagenomics as a new field of research has been developed over the past decade to
elucidate the genomes of the non-cultured microbes with the goal to better understand …
