In taxonomy, Methanofollis is a genus of the Methanomicrobiaceae.[1]

Description and significance

Methanofollis ("a methane-producing bag") is a non-motile, Gram-negative, obligately anaerobic, mesophilic archaeon that produces methane. It grows between the temperatures 20–45 °C (optimum 34–40 °C), and at the pH of around 7.

Genome structure

The genome of the archaeon has not yet sequenced. The G + C content of the DNA is determined to be 60.0%.

Cell structure and metabolism

The cells of Methanofollis are highly irregular cocci, with diameter of 1.25–2.0 µm. The major polar lipids are phospholipids, glycolipids, and phosphoglycolipids. It utilizes H₂/CO₂, formate, 2-propanol/CO₂, and 2-butanol/CO₂ for growth and methanogenesis. No growth has been observed on acetate, trimethylamine, methanol, ethanol, 2-propanol, isobutanol, or 2-butanol as catabolic substrates.

Ecology

Most species of the archaeon are isolated from anaerobic high-rate wastewater bioreactors or solfataric fields. For example, M. tationis was isolated from a solfataric field on Mount Tatio in the Atacama desert in northern Chile.
