New Methane-Producing Archaea Species Discovered in the Human Gut
2025-05-02
An international team of researchers has identified a new species of methane-producing archaea, *Methanobrevibacter intestini* sp. nov. (strain WWM1085), and a novel variant of *Methanobrevibacter smithii*, named GRAZ-2, residing in the human gut. These archaea exhibit unique metabolic characteristics, with *M. intestini* producing significant amounts of succinic acid, potentially linked to inflammation, and GRAZ-2 producing formic acid, possibly affecting the metabolism of other gut inhabitants. This discovery highlights the complexity of the human gut archaeome and opens avenues for research into its role in health and disease.
