Examples of methanogenesis in the following topics:
-
- Methanogenesis in microbes is a form of anaerobic respiration, performed by bacteria in the domain Archaea.
- In methanogenesis, carbon is used as the terminal electron receptor instead of oxygen.
- These products cannot be used in methanogenesis.
- By oxydizing them to acetate, they allow them to be used in methanogenesis.
- The protozoans break down cellulose, releasing H2 which is then used in methanogenesis.
-
- The biochemistry of methanogenesis is relatively complex.
- Methanogenesis also occurs in the guts of humans and other animals, especially ruminants.
- The useful products of methanogenesis are absorbed by the gut.
- Methanogenesis can also be beneficially exploited.
- Acetate is broken down to methane by methanogenesis, a type of anaerobic respiration.
-
- Acidogenesis is the second stage in the four stages of anaerobic digestion: hydrolysis, acidogenesis, acetogenesis, and methanogenesis.
- Finally, methanogenesis is a biological reaction wherein acetates are converted into methane and carbon dioxide, and hydrogen is consumed.
-
- The complete genome sequence from Archaeoglobus fulgidus reveals the presence of a complete set of genes for methanogenesis.
- The function of these genes in A. fulgidus remains unknown, and the lack of the enzyme methyl-CoM reductase does not allow for methanogenesis to occur by a mechanism similar to that found in other methanogens.
-
- Of the remainder of the unique proteins that have an identified function, most belong to the Euryarchaea and are involved in methanogenesis.
-
- Only M. acetivorans and microbes in the genus Methanosarcina use all three known metabolic pathways for methanogenesis.
-
- The protozoans break down cellulose, releasing H2 which is then used in methanogenesis.
-
- Finally, anaerobic fermentation/methanogenesis is an example of a syntrophic relationship between different groups of microorganisms.
- Conversely, the available free energy from methanogenesis is lowered from ΔGº= -131 kJ/mol under standard conditions to ΔG' = -17 kJ/mol at 10−5 atm hydrogen.
-
- Of the remainder of the unique proteins that have an identified function, most belong to the Euryarchaea and are involved in methanogenesis.
-
- Methanogenesis uses a range of coenzymes that are unique to these archaea, such as coenzyme M and methanofuran.
