Cells are nonmotile and Gram-negative. Multicellular filaments are longer than 100 µm in length and 0.2–0.4 µm in width. Spore formation is not observed under any culture conditions. Thermophilic and neutrophilic. Strictly anaerobic chemoorganoheterotroph. No photosynthetic growth is observed. Yeast extract is required for growth. In the presence of yeast extract, carbohydrates and proteinaceous carbon sources are fermented as energy and carbon sources. Nitrate, fumarate, sulfate, sulfite, elemental sulfur, thiosulfate, and Fe (III)-nitrilotriacetate (NTA) are not utilized as electron acceptors. Growth is stimulated in cocultivation with hydrogenotrophic methanogens. Known habitats include thermophilic anaerobic sludge.
DNA G + C content (mol%): 53.7–53.9 (genome sequence).
Type species: Anaerolinea thermophila Sekiguchi, Yamada, Hanada, Ohashi, Harada and Kamagata 2003, 1850VP.
