Methanocalculus is a genus of archaeans in the order Methanomicrobiales, and is known to include methanogens.^[1]

The genome of Methanocalculus is somewhat different from other genera of methanogenic archaea, with less than 90% 16S ribosomal RNA similarity.^[2] The species within Methanocalculus also have a greater tolerance to salt than other microorganisms, and they can live at salt concentrations as high as 125 g/L.^[3] Some species within Methanocalculus are neutrophiles, and Methanocalculus natronophilus, discovered in 2013, is a strict alkaliphile.^[2]
