Methane matters in animals and man: from beginning to end

Abstract

Methanogenic archaea resident in the mammalian gastrointestinal tract have long been recognised for their capacity to participate in interspecies hydrogen transfer, with commensurate positive effects on plant biomass conversion. However, there is also still much to learn about these methanogenic archaea in regards to their metabolic versatility, host adaptation, and immunogenic properties that is of relevance to host health and nutrition.
