Microbiologists discover new species of methane-producing archaea in the human gut An international team of microbiologists from the Medical University of Graz, the DSMZ—German Collection of Microorganisms and Cell Cultures (Braunschweig, Germany)—and the University of Illinois…

Expanding the cultivable human archaeome: Methanobrevibacter intestini sp. nov. and strain Methanobrevibacter smithii ‘GRAZ-2’ from human faeces Two mesophilic, hydrogenotrophic methanogens, WWM1085 and M. smithii GRAZ-2, were isolated from human faecal samples. WWM1085 was isolated from an individual in the United States and represents a nove...

New @fwf-at.bsky.social CoE Microplanet Publication in BMC Microbiology from the lab of @chmoei.bsky.social @medunigraz.at shows high-methanogenic phenotype in #centenarians with #Methanobrevibacter smithii dominance and youth-like #archaeal profiles. rdcu.be/egk03

Realized I never posted about our recent article: we revisited prior claims linking #Methanobrevibacter to #MS using metagenomes from 115 patients & 115 controls. No overall #archaeome differences, defeating earlier hypotheses. But treatment was associated with elevated M. smithii & M. sp900766745.

Age-related dynamics of predominant methanogenic archaea in the human gut microbiome

New paper! We analyzed gut #microbiomes of 250+ individuals (ages 19–109).
#Centenarians often show a high-methanogen “human cow” phenotype 🐄, with #Methanobrevibacter smithii dominance and youth-like archaeal profiles. #Archaea may stabilize networks in aging.
