Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

The Archaea occupy a key position in the Tree of Life, and are a major fraction of microbial
diversity. Abundant in soils, ocean sediments and the water column, they have crucial roles …

Microbial life in marine sediment contributes substantially to global biomass and is a crucial
component of the Earth system. Subseafloor sediment includes both aerobic and anaerobic …

Methanogenesis is the primary biogenic source of methane in the atmosphere and a key
contributor to climate change. The long-standing dogma that methanogenesis originated …

To describe a microbe's physiology, including its metabolism, environmental roles, and
growth characteristics, it must be grown in a laboratory culture. Unfortunately, many …

Background Archaea represent a significant fraction of Earth's biodiversity, yet they remain
much less well understood than Bacteria. Gene surveys, a few metagenomic studies, and …

Studies of marine benthic archaeal communities are updating our view of their taxonomic
composition and metabolic versatility. However, large knowledge gaps remain with regard to …

BACKGROUND Archaea have been recognized as a major domain of life besides Bacteria
and Eukarya for about 40 years. Much of the pioneering research on archaeal organisms …

Methanogenic and methanotrophic archaea play important roles in the global flux of
methane. Culture-independent approaches are providing deeper insight into the diversity …

Bathyarchaeota, formerly known as the Miscellaneous Crenarchaeotal Group, is a phylum of
global generalists that are widespread in anoxic sediments, which host relatively high …
