Methylacidiphilum infernorum is an extremely acidophilic methanotrophic aerobic bacteria first isolated and described in 2007 growing on soil and sediment on Hell’s Gate, New Zealand. Similar organisms have also been isolated from geothermal sites on Italy and Russia.
A polyextremophile, these non-motile rods grows optimally at pH between 2.0 to 2.5 and temperature of 60 °C. It is a methanotrophic obligated bacteria that grows at 25% (v/v) of methane in air. It is also very dependant on carbon dioxide concentrations to grow, optimally at 8% (v/v) CO2 in air.
Due to its classification in the phylum Verrucomicrobia and its extreme acidophilic phenotype M. infernorum is unique between all known methanotrophs.
It has a single circular chromosome of 2,287,145 base pairs. Under genome analysis it was found that M. infernorum may use a novel methylotrophic pathway because it encodes methane monooxygenase enzymes but lacks known genetic modules for methanol and formaldehyde oxidation.
All the enzymes required for the Calvin Benson Bassham cycle were identify by genetic analysis.
It has been predicted that M. infernorum possess most of the key metabolic pathways for the biosynthesis of all amino acids, nucleotides and cofactors, with the sole exception of the cobalamin cofactor.
