Methanothrix soehngenii explained

Methanothrix soehngenii is a species of methanogenic archaea. Its cells are non-motile, non-spore-forming, rod-shaped (0.8×2 μm) and are normally combined end to end in long filaments, surrounded by a sheath-like structure. It is named in honour of N. L. Söhngen.^[1]

Metabolism

Unlike other methanogenic archaea, Methanothrix soehngenii cannot reduce carbon dioxide with hydrogen to produce methane. Its sole source of energy is acetate.

Genome

The tRNA^ala gene of Methanothrix soehngenii differs from those of other archaea in that it encodes a terminal CCA 3′.^[2]
