Resumen
El presente estudio es una revisión bibliográfica del dominio Archaea, principalmente de las arqueas de
tipo metanógeno. Las arqueas de tipo metanógeno se conocen como habitantes intestinales humanos
desde hace más de 30 años a través de la detección de metano en el aliento y el aislamiento de dos
especies metanogénicas que pertenecen al orden Methanobacteriales, Methanobrevibacter smithii y
Methanosphaera stadtmanae. Durante la última década, la diversidad de arqueas encontradas en el
tracto gastrointestinal humano (GIT) se ha ampliado mediante la identificación de secuencias y el
cultivo de nuevas cepas. Aquí se proporciona información sobre este dominio y su posible papel en la
fisiología y la salud intestinal; así como la influencia de la dieta en la microbiota intestinal, en particular
del aceite de oliva. Cabe destacar el interés de estas especies y su uso como arqueobióticos.
The present study is a bibliographic review of the Archaea domain, mainly of achaea methanogenic type. Methanogenic archaea have been known as human intestinal inhabitants for more than 30 years through the detection of methane in the breath and the isolation of two methanogenic species belonging to the order Methanobacterial, Methanobrevibacter smithii and Methanosphaera stadtmanae. Over the past decade, the diversity of archaea found in the human gastrointestinal tract (GIT) has been expanded through sequence identification and cultivation of new strains. Here, information is provided on this domain and its possible role in intestinal physiology and health; as well as the influence of diet on intestinal microbiota, in particular of olive oil. The interest of these species and their use as archaeobiotics should be highlighted.
