Geothermal systems in Yellowstone National Park (YNP) provide an outstanding opportunity
to understand the origin and evolution of metabolic processes necessary for life in extreme …

Geochemical, molecular, and physiological analyses of microbial isolates were combined to
study the geomicrobiology of acidic iron oxide mats in Yellowstone National Park. Nineteen …

Recent discoveries suggest that the candidate superphyla Patescibacteria and DPANN
constitute a large fraction of the phylogenetic diversity of Bacteria and Archaea. Their small …

Novel lineages of the phylum Thaumarchaeota are endemic to thermal habitats, and may
exhibit physiological capabilities that are not yet observed in members of this phylum. The …

The discovery of archaeal lineages is critical to our understanding of the universal tree of
life and evolutionary history of the Earth. Geochemically diverse thermal environments in …

Background Nanoarchaeota are obligate symbionts of other Archaea first discovered 16
years ago, yet little is known about this largely uncultivated taxon. While Nanoarchaeota …

The candidate archaeal phylum ‘Aigarchaeota’ contains microorganisms from terrestrial
and subsurface geothermal ecosystems. The phylogeny and metabolic potential of …

The biogeochemical cycle of iron is intricately linked to numerous element cycles. Although
biological processes that catalyze the reductive side of the iron cycle are established, little is …

Yellowstone Lake (Yellowstone National Park, WY, USA) is a large high-altitude (2200 m),
fresh-water lake, which straddles an extensive caldera and is the center of significant …

Biomineralized ferric oxide microbial mats are ubiquitous features on Earth, are common in
hot springs of Yellowstone National Park (YNP, WY, USA), and form due to direct interaction …
