Aquifex is a genus of bacteria, one of the few in the phylum Aquificae. The two species generally classified in Aquifex are A. pyrophilus and A. aeolicus. Both are highly thermophilic, growing best in water temperature of 85 °C to 95 °C. They are true bacteria (also known as the domain Eubacteria) as opposed to the other inhabitants of extreme environments, the Archaea.[1] For other uses, see Genus (disambiguation). ...

Both species of Aquifex are rod-shaped bacteria with a length of 2 to 6 µm and a diameter of around 0.5 µm. They are non-sporeforming, Gram negative autotrophs. Aquifex means water-maker in Latin, and refers to the fact that its method of respiration creates water. Aquifex tend to form cell aggregates composed of up to 100 individual cells. A micrometre (American spelling: micrometer, symbol µm) is an SI unit of length equal to one millionth of a metre, or about a tenth of the diameter of a droplet of mist or fog. ... This article or section is in need of attention from an expert on the subject. ... Gram-negative Pseudomonas aeruginosa bacteria (pink-red rods). ... An autotroph (in Greek eauton = self and trophe = nutrition) is an organism that produces its own cell mass and organic compounds from carbon dioxide as sole carbon source, using either light or chemical compounds as a source of energy. ... // In animal physiology, respiration is the transport of oxygen from the ambient air to the tissue cells and the transport of carbon dioxide in the opposite direction. ...


Aquifex are thermophilic and often grow near underwater volcanoes or hot springs.[2] A. aeolicus requires oxygen to survive, but can grow in levels of oxygen as low as 7.5 ppm. A. pyrophilus can even grow anaerobically by reducing nitrogen instead of oxygen. Like other thermophilic bacteria, Aquifex has important uses in industrial processes. For other uses, see Volcano (disambiguation). ... Green Dragon Spring at Norris Geyser A hot spring is a place where warm or hot groundwater issues from the ground on a regular basis for at least a predictable part of the year, and is significantly above the ambient ground temperature (which is usually around 55~57 F or...

It has been suggested that Anoxic sea water, Oxygen minimum zone, and Hypoxic zone be merged into this article or section. ... General Name, Symbol, Number nitrogen, N, 7 Chemical series nonmetals Group, Period, Block 15, 2, p Appearance colorless gas Standard atomic weight 14. ...


The genome of A. aeolicus has been successfully mapped.[3],[4] This was made easier by the fact that the length of the genome is only about a third of the length of the genome for E. coli. Comparison of the A. aeolicus genome to other organisms showed that around 16% of its genes originated from the Archaea domain. Members of this genus are thought to be some of the earliest members of the eubacteria domain. In biology the genome of an organism is the whole hereditary information of an organism that is encoded in the DNA (or, for some viruses, RNA). ... Binomial name Escherichia coli T. Escherich, 1885 Escherichia coli (usually abbreviated to E. coli) is one of the main species of bacteria that live in the lower intestines of warm-blooded animals (including birds and mammals) and are necessary for the proper digestion of food. ... Phyla Crenarchaeota Euryarchaeota Korarchaeota Nanoarchaeota Archaea are a major division of microorganisms. ...


A. aeolicus was discovered north of Sicily, while A. pyrophilus was first found just north of Iceland. Sicily (Sicilia in Italian and Sicilian) is an autonomous region of Italy and the largest island in the Mediterranean Sea, with an area of 25,708 km² (9,926 sq. ...

Aquifex - Wikipedia, the free encyclopedia (302 words)
Aquifex is a genus of bacteria, one of the few in the phylum Aquificae.

Aquifex are thermophilic and often grow near underwater volcanoes or hot springs.
Brainstorms: The Utility of IC (4727 words)
Aquifex aeolicus, a denizen of Yellowstone Park that lives at 5 degrees below the boiling point of water, is the deepest branching of all known bacteria.
In the light of evidence suggesting that the oldest region of the ribosomal RNA tree lies on the branch leading into the bacterial kingdom, Aquifex provided grounds for the claim that it was the nearest living cousin of the universal ancestor.
The presence of novel genes in Aquifex would require either multiple new gene origins in the Aquifex lineage since the time of the ancestor (rendering it a poor analog for the ancestor), or multiple losses of genes in the other prokaryote lineages.
