- 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.
