| 41. | Moreover, these methanogens change the structure of the tailings pond and help the pore water efflux to reuse for processing oil sands.
|
| 42. | There are over 50 described species of methanogens, which do not form a monophyletic group, although all methanogens belong to Archaea.
|
| 43. | There are over 50 described species of methanogens, which do not form a monophyletic group, although all methanogens belong to Archaea.
|
| 44. | Many microorganisms affect anaerobic digestion, including acetic acid-forming bacteria ( acetogens ) and methane-forming archaea ( methanogens ).
|
| 45. | This is supported by the presence of 10 conserved signature proteins that are uniquely found in all methanogens and " Archaeoglobus ".
|
| 46. | This process affects the carbon cycle : methanogens can participate in interspecies hydrogen transfer combining H 2 and CO 2 to produce CH 4.
|
| 47. | An exception to this wide distribution is a group of unique cofactors that evolved in methanogens, which are restricted to this group of archaea.
|
| 48. | Some methanogens, called hydrogenotrophic, use carbon dioxide ( CO 2 ) as a source of carbon, and hydrogen as a reducing agent.
|
| 49. | Additionally, 10 proteins found in all methanogens which are shared by " Archaeoglobus ", suggest that these two groups are related.
|
| 50. | Little is understood about the function of these " class IV " " nif " genes, though they occur in many methanogens.
