'''''Methanothermobacter''''' is a genus of archaeans in the family Methanobacteriaceae.<ref name=NCBI>{{cite web |author=C.L.

They are methanogens; they use carbon dioxide and hydrogen as substrates to produce methane for energy.<ref>{{cite book|editor1=Stanley Falkow|editor2=Eugene Rosenberg|editor3=Karl-Heinz Schleifer|editor4=Erko Stackebrandt|title=The Prokaryotes|url=https://books.google.com/books?id=swciHNNWZDEC&q=%22genus+methanothermobacter%22&pg=PA241|volume=3|publisher=Springer Science & Business Media|pages=241|date=2006-10-10|access-date=2016-08-30|isbn=0387254935}}</ref>
