Contents Notes
Free-Living Protozoa with Endosymbiotic Methanogens -- Anaerobic Ciliates and Their Methanogenic Endosymbionts -- Symbiotic Methanogens and Rumen Ciliates -- The Methanogenic and Eubacterial Endosymbionts of Trimyema -- Termite Gut Flagellates and Their Methanogenic and Eubacterial Symbionts -- Methanogens in the Digestive Tract of Termites -- Methanogenic Archaea in Humans and Other Vertebrates -- Methanogens in the Gastro-Intestinal Tract of Animals -- Syntrophy in Methanogenic Degradation -- Hydrogenosomes -- Evolution of Prokaryote-Animal Symbiosis from a Genomics Perspective. Methanogens are prokaryotic microorganisms that produce methane as an end-product of a complex biochemical pathway. They are strictly anaerobic archaea and occupy a wide variety of anoxic environments. Methanogens also thrive in the cytoplasm of anaerobic unicellular eukaryotes and in the gastrointestinal tracts of animals and humans. The symbiotic methanogens in the gastrointestinal tracts of ruminants and other "methanogenic" mammals contribute significantly to the global methane budget; especially the rumen hosts an impressive diversity of methanogens. This monograph deals with methanogenic endosymbionts of anaerobic protists, in particular ciliates and termite flagellates, and with methanogens in the gastrointestinal tracts of vertebrates and arthropods. Further reviews discuss the genomic consequences of living together in symbiotic associations, the role of methanogens in syntrophic degradation, and the function and evolution of hydrogenosomes, hydrogen-producing organelles of certain anaerobic protists.
