Meth·a·no·bac·ter·i·a·ce·ae

(meth'ă-nō-bak-tēr'ē-ā'sē-ē),
Archaea bacteria containing gram-negative and gram-positive, motile or nonmotile, strictly anaerobic rods and cocci, which obtain energy either by the reduction of carbon dioxide to form methane or by the fermentation of compounds such as acetate and methanol with the production of methane and carbon dioxide; they are found in anaerobic habitats such as sediments of natural waters, soil, anaerobic sewage digestors, and the gastrointestinal tract of animals.

Predominant hindgut archaeal species among methanogens were Methanobrevibacter (75, 72, and 49%), Methanosphaera (3.3, 2.3, and 3.4%), and Methanobacteriaceae (1.2, 0.6, and 0.7%) population in control, 15, and 30% PB, respectively, and they were linearly decreased or increased with increasing PB concentration (P < 0.05).

Phylogenetic analyses of the methanogenic Archaea community revealed a great diversity of methanogens in the permafrost including families of Methanobacteriaceae, Methanomicrobiaceae, Methanosarcinaceae, Methanosaetaceae [16,17,19,20], methanogen group Rice cluster I (RC-I) and uncultured Rice cluster II (RC II) within the phylogenetic radiation of Methanosarcinales and Methanomicrobiales [19, 21-23] and ZC-I affiliated to Methanosarcinales [20], permafrost cluster I affiliated to Methanosarcinaceae [19], and permafrost cluster II and III affiliated to Methanosarcinales [19].
