In taxonomy, Picrophilus is a genus of the Picrophilaceae.^[1]

The genus Picrophilus is an extremely acidophilic genus within the Euryarchaeota. These microbes are the most acidophilic organisms currently known, with the ability to grow at a pH of 0.06. They are obligate acidophiles and are unable to maintain their membrane integrity at pH values higher than 4. While phylogenetically related to other organisms within the Thermoplasmata, unlike Thermoplasma and Ferroplasma, Picrophilus contains an S-layer cell wall.
