How To Use methanogen In A Sentence

  • When sulphate availability is increased sulphate reducing bacteria proliferate and eventually may outcompete methanogens when the sulphate supply is sufficient.
  • These results further indicate that the formation of the siderite concretions is not associated with the activity of methanogenic bacteria.
  • Invitro, sulphate reducing bacteria compete with methanogenic bacteria for hydrogen when sulphate is present.
  • Between 30 and 50% of people in western countries harbour methanogenic bacteria in their colons.
  • In marine sediments and faeces, sulphate reducing bacteria outcompete methanogenic bacteria because of their higher affinity for such substrates.
  • Dog feces naturally contain bacteria called methanogens, which use hydrogen to break down carbon dioxide into microbial food.
  • Breath methane was measured and viable counts and metabolic activities of methanogenic bacteria and sulphate reducing bacteria determined in faeces.
  • In this regard, both the phylogeny and function of archaeal selenoproteins are consistent with the argument that the archaeal ancestor was a methanogen.
  • Since the discovery that methanogens belong to the Archaea and not to the Bacteria, a number of other archaeal groups have been discovered.
  • In the discussion, the authors present additional evidence that supports their finding, including, but not limited to: (a) the inability to detect cytochromes within the methanogens; (b) the fact that the cell walls of methanogens do not contain peptidoglycan; (c) the 23S rRNA sequence is also divergent from typical bacteria.
