Acidisoma
Acidisoma is a genus in the phylum Proteobacteria ( Bacteria). It contains two species, Acidisoma tundrae and Acidisoma sibiricum, both two acidophilic (pH 3.0–7.6) and psychrotolerant (2–30 °C) bacteria with poly-β-hydroxybutyrate granules, isolated from acidic Sphagnum-dominated tundra and Siberian wetlands in Russia.
