  • The Microbiologists have discovered a previously unknown methane-producing archaea species in the human gut.
  • They named it Methanobrevibacter intestini sp. nov., strain WWM1085.
  • It survives only in oxygen-free environments and produces methane.
  • The team also isolated a new variant of Methanobrevibacter smithii, called GRAZ-2.
  • Archaea are one of the three recognized domains of living organisms, along with bacteria and eukaryotes.
  • One group of archaea, known as methanogens, produces methane by breaking down hydrogen and carbon dioxide.
  • These microbes are vital to metabolic processes in animals – including humans.
