archaean

We know that individual archaea ingest bacteria for food -- they still do it today.

Archaea represent <3.3% of the total rRNA (both 16S and 18S) in the rumen [3].

Cassini detected formaldehyde on Enceladus, which can disrupt the life cycle of even the hardiest archaea. M.

Adair K, Schwartz E (2008) Evidence that ammonia-oxidizing archaea are more abundant than ammonia-oxidizing bacteria in soils along an elevation gradient in northern Arizona, USA.

This manuscript aims at providing an overview of the various roles that Archaea have in bioremediation.

Viruses that infect archaea and bacteria, for example, are not known to infect eukarya.

The study of archaeal DNA replication was initiated shortly after the recognition of Archaea as the third domain of life (Ishino et al., 2013).

A study by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the Medical University of Graz has found that the skin microbiome also contains Archaea, a type of extreme-loving microbe, and that the amount of it varies with age.

The study suggests that microorganisms, including bacteria and archaea, might one day be used to enhance methane production--perhaps by sustaining the energy a site can produce after fracturing ends.

But Edgcomb and others have found fungi, bacteria, and other single-celled organisms called archaea beneath the seafloor that use alternative biochemical reactions and alternative chemicals such as hydrogen, sulfur, and methane to produce energy.

Microbial species are all forms of life too small to be seen with the naked eye, including all single-celled organisms, such as bacteria and archaea, as well as certain fungi.

Two of them, Archaea and Bacteria, comprise of single-celled organisms without a nucleus or organelles but differ in other properties.
