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

Methane is the final product of the anaerobic decomposition of organic matter. The
conversion of organic matter to methane (methanogenesis) as a mechanism for energy …

Methane is a key compound in the global carbon cycle that influences both nutrient cycling
and the Earth's climate. A limited number of microorganisms control the flux of biologically …

Despite numerous surveys of gene and species content in heterotrophic microbial
communities, such as those found in animal guts, oceans, or soils, it is still unclear whether …

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 …

Multicellular assemblages of microorganisms are ubiquitous in nature, and the proximity
afforded by aggregation is thought to permit intercellular metabolic coupling that can …

The anaerobic oxidation of methane coupled to sulfate reduction is a microbially mediated
process requiring a syntrophic partnership between anaerobic methanotrophic (ANME) …

It is well known that atmospheric concentrations of carbon dioxide (CO2)(and other
greenhouse gases) have increased markedly as a result of human activity since the …

Anaerobic oxidation of methane (AOM) is catalyzed by anaerobic methane‐oxidizing
archaea (ANME) via a reverse and modified methanogenesis pathway. Methanogens can …

Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …
