Methanocalculus is a genus of the 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]

Nomenclature

The name "Methanocalculus" has Latin roots: "methano" for methane and "calculus" for gravel. Overall, it means gravel-shaped organism that produces methane.[3]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[4] and National Center for Biotechnology Information (NCBI).[1]
