Archaea
what is the role of Archaea
It is to play crucial roles in global biogeochemical cycles, including the carbon, nitrogen, and sulfur cycles
What is the shape of Sulfolobus Solfatarcius?
Circular shape
Where does Methanobrevibacter smithii live?
Gut/mammal digestive system.
What is nitrososphaera Viennensis?
Nitrosophaera species was isolated from activated sludge and is considered a prominent example of a bacterium involved in nitrification in wastewater systems.
What are Nanoarchaeum Equitans?
One of the smallest known archaea
How many phyla does this kingdom have?
31 to 35
How does Sulfolobus Solfatarcius respirate?
Primarily aerobic.
What does Methanobrevibacter smithii create as a byproduct of its energy production?
Methane.
What is binary fission?
Nitrosophaera is asexual and occurs through this method of cell division, where one parent cell splits into two genetically identical daughter cells.
What are hydrothermal vents?
Nanoarchaeum Equitans live in these extremely hot, deep-sea environments.
How do archaea divide?
Through binary fission.
What Phylum is Sulfolobus Solfatarcius?
Thermoproteota
Where was Methanobrevibacter smithii found?
was found in a sewage digester in the USA in 1981.
What is its significance in the biochemical process?
The enzyme that allows Nitrosophaera to oxidize ammonia into hydroxylamine is encoded by this gene
What is Ignicoccus hospitalis?
This archaeon is a host for Nanoarchaeum Equitans.
What best describes Archaea?
A domain of microorganisms characterized by distinct transcription and translation machineries
Why is Solfolobus Solfatarcius sought after?
The enzymes are unique, as it is a source of novel enzymes called Ëxtremozymes,”which function under extreme conditions and are of interest for industrial and biotechnological applications.
What phylum is Methanobrevibacter under?
Euryarchaeota.
What’s the functional role of this nitrososphaera in ammonia oxidation?
it adjusts its gene expression, particularly for the amoA gene.
What is symbiosis?
Nanoarchaeum Equitans cannot survive on its own, so it has this type of close relationship with its host.
what are 4 types of Archaea
The methanogens, the extreme halophiles, the sulfate-reducing archaea, and the extreme thermophiles.
How does the Symbiotic relationship work?
Aerobic Sulfur Oxidizer: This organism consumes oxygen, creating the necessary low-oxygen environment for the archaeon. Archaea: This organism uses anaerobic respiration to survive, turning sulfate into sulfide, which the sulfur oxidizer then consumes.
How does Methanobrevibacter smithii blend in with the host?
By changing it’s cell walls proteins and sugars to blend in.
How does this affect the nitrogen cycle?
The presence of Nitrosophaera can be an indicator of this type of environmental quality, especially when the levels of ammonia are high.
What is adaptable?
Its tiny size and simple structure show how life can do this in extreme conditions.
