Characteristic and genera

Archaeoglobaceae have three genera and here are some brief differences between them:

- Archaeoglobus: This genus contains the most well-known and studied members of the Archaeoglobaceae family. They are thermophilic sulfate-reducing bacteria that are found in hydrothermal vents and oil reservoirs. They can grow at high temperatures and use a variety of organic compounds as electron donors(Brileya et al 2014).

- Ferroglobus: This genus contains a single species, Ferroglobus placidus, which is found in hydrothermal vents. They are thermophilic and can grow at high temperatures, but they differ from other members of the family in that they use iron as an electron donor instead of organic compounds( Brileya et al2014).

- Geoglobus: This genus contains a single species, Geoglobus acetivorans, which is found in hydrothermal vents. They are thermophilic and can grow at high temperatures, and they differ from other members of the family in that they use acetate as an electron donor ( Brileya et al 2014).

Mode of metabolism

Archaeoglobaceae are known for their unique mode of metabolism, which involves the use of sulfate as their terminal electron acceptor for respiration (Marietou, Angeliki 2021). This process is called dissimilatory sulfate reduction, and it allows the bacteria to produce energy in the absence of oxygen (Marietou, Angeliki 2021). This means that Archaeoglobaceae can use sulfate instead of oxygen to generate energy from organic compounds (Marietou, Angeliki 2021).

living environments

Archaeoglobus species are found in a variety of extreme environments, including deep-sea hydrothermal vents, oil reservoirs, and hot springs. These environments are characterized by high temperatures, high pressures, and low oxygen concentrations, which make them inhospitable to most other forms of life (Topçuoğlu et al 2019). They are able to thrive in these environments by using a variety of metabolic pathways to obtain energy, and by producing a range of heat-shock proteins and other stress-response mechanisms that help them to survive in these extreme conditions. They are extremophiles, which means they can also be found in environments that are high in salt content, such as in salt flats or Salt Lake. Archaeoglobaceae are able to thrive in these extreme environments because they are able to use a variety of different minerals and gases to make energy. For example, some species of Archaeoglobaceae are able to use sulfur in a process called dissimilatory sulfate reduction, which allows them to produce energy without the need for oxygen. Other species of Archaeoglobaceae are able to use carbon dioxide or hydrogen gas as a source of energy(Topçuoğlu et al 2019).

In addition to their ability to use different energy sources, some species of Archaeoglobaceae are also known to form symbiotic relationships with other organisms. For example, some species of Archaeoglobaceae have been found living in association with tube worms, which are able to extract nutrients from the hydrothermal vent environment and provide them to the bacteria in exchange for energy. These symbiotic relationships are thought to be important for the survival of both the bacteria and the tube worms in these extreme environments(Topçuoğlu et al 2019).
