A wide array of microorganisms, including many novel, phylogenetically deeply rooted taxa,
survive and thrive in extreme environments. These unique and reduced-complexity …

The archaeal domain is currently divided into two major phyla, the Euryarchaeota and
Crenarchaeota. During the past few years, diverse groups of uncultivated mesophilic …

The widespread occurrence and diversity of ammonia oxidizing Archaea suggests their
contribution to the nitrogen cycle is of global significance. Their distribution appeared limited …

Bacterial Biogeochemistry, Third Edition focuses on bacterial metabolism and its relevance
to the environment, including the decomposition of soil, food chains, nitrogen fixation …

Although most hypotheses to explain the emergence of the eukaryotic lineage are
conflicting, some consensus exists concerning the requirement of a genomic fusion between …

The domain Archaea has historically been divided into two phyla, the Crenarchaeota and
Euryarchaeota. Although regarded as members of the Crenarchaeota based on small …

Microbes of the phylum Aigarchaeota are widely distributed in geothermal environments, but
their physiological and ecological roles are poorly understood. Here we analyze six …

Recent progress has revealed that the capture of genetic resources of complex microbial
communities in metagenome libraries allows the discovery of a richness of new enzymatic …

Trace metals have been an important ingredient for life throughout Earth's history. Here, we
describe the genome-guided cultivation of a member of the elusive archaeal lineage …

Abstract Great Boiling Spring is a large, circumneutral, geothermal spring in the US Great
Basin. Twelve samples were collected from water and four different sediment sites on four …
