Methanogens are prokaryotic microorganisms that produce methane as an end-product of a posh biochemical pathway. they're strictly anaerobic archaea and occupy a large choice of anoxic environments. Methanogens additionally thrive within the cytoplasm of anaerobic unicellular eukaryotes and within the gastrointestinal tracts of animals and people. The symbiotic methanogens within the gastrointestinal tracts of ruminants and different “methanogenic” mammals give a contribution considerably to the worldwide methane funds; in particular the rumen hosts a powerful range of methanogens. This monograph offers with methanogenic endosymbionts of anaerobic protists, specifically ciliates and termite flagellates, and with methanogens within the gastrointestinal tracts of vertebrates and arthropods. extra reports talk about the genomic results of dwelling jointly in symbiotic institutions, the function of methanogens in syntrophic degradation, and the functionality and evolution of hydrogenosomes, hydrogen-producing organelles of convinced anaerobic protists.

Example text
The endosymbionts formed two clusters that belong to two different orders of methanogens (Methanobacteriales vs. Methanomicrobiales). One cluster contained the endosymbionts of the freeliving ciliate species; the other contained the endosymbionts of the gut-dwelling ciliate species. Notably, the endosymbionts of the freshwater ciliates clustered among methanogens (Methanomicrobiales) living predominantly in freshwater sediments, whereas the endosymbionts of the intestinal ciliates clustered among predominantly intestinal or faecal methanogens (Methanobacteriales).
