Methanogenic archaea: list of the JCM strains and a recipe for the preparation of anaerobic culture media are released.
Methanogenic archaea are strict anaerobes that grow on limited substrates, such as CO2 and H2, formate, methanol and/or acetate, coupled with methane production. Currently all cultivated species belong to the phylum Methanobacteriota (formerly known as Euryarchaeota). They are quite physiologically diverse, and widespread in natural and anthropogenic anoxic habitats. Methane is known as the most important greenhouse gas after CO2, and a large part of the atmospheric methane comes from the methanogenesis. Meanwhile, methanogens are major players in anaerobic digesters, working together with other anaerobic microorganisms to break down organic waste and produce methane-containing biogas.
Recently, JCM has released a list of the methanogenic archaeal strains available from JCM and a recipe for the preparation of anaerobic culture media to cultivate methanogens and other strictly anaerobic microorganisms:
