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.^[1]^[2]^[3] 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 and 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 dependent on carbon dioxide concentrations to grow, optimally at 8% (v/v) CO₂ in air.^[1]

Due to its classification in the phylum Verrucomicrobiota and its extreme acidophilic phenotype M. infernorum is unique between all known methanotrophs.^[1]
