What are methanogens?
Q: What are methanogens?
A: Methanogens are microorganisms that produce methane as a metabolic byproduct in anoxic conditions.
Q: What is the domain of methanogens?
A: Methanogens belong to the archaea domain, which is different from bacteria.
Q: Where are methanogens commonly found?
A: Methanogens are common in wetlands where they make marsh gas, and in the digestive tracts of animals such as ruminants and humans.
Q: How is methane produced in marine sediments?
A: Methane is produced in marine sediments when sulfates are low, and this occurs below the top layers.
Q: What is the role of methanogenic archaea populations in anaerobic wastewater treatments?
A: Methanogenic archaea populations play an important role in anaerobic wastewater treatments.
Q: Where can extremophilic methanogens be found?
A: Extremophilic methanogens can be found in environments such as hot springs, submarine hydrothermal vents, and the "solid" rock of the Earth's crust, kilometers below the surface.
Q: What is the process through which methanogens convert acetic acid to methane?
A: Methanogens convert acetic acid to methane in a fermentation process.
