Exempel på hur man kan använda ARCHAEON i en mening

• 2 billion years ago an archaeon absorbed a bacterium through phagocytosis, that eventually became the mitochondria that provide energy to almost all living eukaryotic cells.
• An endolith or endolithic is an organism (archaeon, bacterium, fungus, lichen, algae or amoeba) that is able to acquire the necessary resources for growth in the inner part of a rock, mineral, coral, animal shells, or in the pores between mineral grains of a rock.
• Nanoarchaeum appears to be an obligate symbiont on the archaeon Ignicoccus; it must be in contact with the host organism to survive.
• In the Frasassi Caves in Italy, over 70% of cells in Snottite have been identified as Acidithiobacillus thiooxidans, with smaller populations including an archaeon in the uncultivated 'G-plasma' clade of Thermoplasmatales (>15%) and a bacterium in the Acidimicrobiaceae family (>5%).
• placidus was the first archaeon discovered that can anaerobically oxidize iron coupled to the reduction of nitrate.
• Halobacterium can be identified in bodies of water by the light-detecting pigment bacteriorhodopsin, which not only provides the archaeon with chemical energy, but adds to its reddish hue as well.
• Pfu DNA polymerase is an enzyme found in the hyperthermophilic archaeon Pyrococcus furiosus, where it functions to copy the organism's DNA during cell division (thermostable DNA polymerase).
• Viral eukaryogenesis is the hypothesis that the cell nucleus of eukaryotic life forms evolved from a large DNA virus in a form of endosymbiosis within a methanogenic archaeon or a bacterium.
• The archaeon Sulfolobus solfataricus RadA recombinase catalyzes DNA pairing and strand exchange, central steps in recombinational repair.
• Gene transfer and genetic exchange have been studied in the halophilic archaeon Halobacterium volcanii and the hyperthermophilic archaeons Sulfolobus solfataricus and Sulfolobus acidocaldarius.
• A thermophile that grows in near-boiling temperatures, Nanoarchaeum appears to be an obligatory symbiont on the archaeon Ignicoccus; it must be in contact with the host organism to survive.
• The order contains archaeon with one of the largest genome, Methanosarcina acetivorans C2A, genome size 5,75 Mbp.
• Halobacterium salinarum, formerly known as Halobacterium cutirubrum or Halobacterium halobium, is an extremely halophilic marine obligate aerobic archaeon.
• The archaeon utilizes maltose, starch, malate, yeast extract, peptone, beef extract, casamino acids and gelatin as carbon sources, cannot utilize D-arabinose, D-fructose, lactose, sucrose, D-xylose, acetate, butyrate, formate, fumarate, propionate, pyruvate, succinate, methanol, formamide, methylamine or trimethylamine.
• Sulfurisphaera is a facultatively anaerobic, thermophilic, Gram-negative archaeon that occurs in acidic solfataric fields.
• boonei, is an extremophile, a thermoacidophilic archaeon that lives in oceanic deep-sea hydrothermal vents, that has been shown to produce antibiotics against common pathogenic bacteria.
• Haloferax massilisiensis or Haloferax massiliense was first published in 2016 and again in 2018 as human associated halophilic archaeon.
• Methanofollis ("a methane-producing bag") is a non-motile, Gram-negative, obligately anaerobic, mesophilic archaeon that produces methane.
• Ftr from the mesophilic methanogen Methanosarcina barkeri and the sulphate-reducing archaeon Archaeoglobus fulgidus have a similar structure.
• This virus was isolated from hypersaline water in Australia and was able to be cultured on the halophilic archaeon Haloarcula hispanica.
