Thermotolerant or moderately thermophilic, acidophilic bacterium. Small, rod-shaped cells, which may be in filaments of variable length. Optimum growth occurs at 45–50°C and approximately pH 2. Heterotrophic growth occurs on yeast extract, during which cells are motile. Autotrophic growth occurs on ferrous iron. Most rapid growth is observed aerobically with ferrous iron and yeast extract. Found in warm, acidic, mineral sulfide-rich environments.
DNA G+C content (mol%): 67–68 (T m and HPLC).
Type species: Acidimicrobium ferrooxidans Clark and Norris 1996a, 1189VP (Effective publication: Clark and Norris 1996b, 790.).
