Hypophosphite is a naturally-occurring selective inhibitor of syntrophic methanogenesis

This study identifies hypophosphite as a natural inhibitor of syntrophic methanogenesis, offering a potential strategy for methane control in ecosystems.

Organic carbon oxidation state shapes fermentative methanogenic microbiomes and controls greenhouse gas fluxes

The paper investigates how organic carbon oxidation state affects microbiome composition and greenhouse gas fluxes in anaerobic rice paddy sediments.

Acetogenic methane-carbon monoxide comproportionation: an exergonic but unobserved microbial metabolism

This paper identifies acetogenic methane-carbon monoxide comproportionation as an exergonic microbial metabolism that could support life in anoxic environments on Earth and other planetary bodies.

Lithosyntrophy: Obligate syntrophy in a phosphite-oxidizing, methanogenic culture

This paper describes a novel syntrophic interaction called lithosyntrophy, where phosphite oxidation drives hydrogenotrophic methanogenesis in an obligate partnership between a bacterium and a methanogen.
