Geothrix fermentans is a rod-shaped anaerobic bacterium. It is about 0.1 µm in diameter and ranges from 2-3 µm in length. Cell arrangement occurs singly and in chains. Geothrix fermentans can normally be found in aquatic sediments such as in aquifers. As an anaerobic chemoorganotroph this organism is best known for its ability to use electron acceptors Fe(III) as well as other high potential metals. It also uses a wide range of substrates as electron donors.
