Methanobacteriati

Although these marine Methanobacteriati are difficult to culture and study in a lab, genomic sequencing suggests that they are motile heterotrophs.

[9] Some Methanobacteriati are highly adaptable; an order called Halobacteriales are usually found in extremely salty and sulfur-rich environments but can also grow in salt concentrations as low as that of seawater 2.5%.

[5] The LPSN, which aligns itself with the Code, adopts this view and[10] lists the earlier Methanobacteriati as a invalidly published phylum.

[15] The taxon Methanobacteriati is also listed in the Bergey's Manual of Systematics of Archaea and Bacteria, but this is because the latest version of the chapter was published in 2017.
