''Methanothrix soehngenii'' is a species of
methanogenic archaea. Its cells are non-
motile, non-
spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, f ...

) 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.
Metabolism
Unlike other methanogenic archaea, ''Methanothrix soehngenii'' cannot reduce
carbon dioxide with
hydrogen to produce
methane. Its sole
source of energy
Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reus ...

Genome
The
tRNAala gene of ''Methanothrix soehngenii'' differs from those of other archaea in that it encodes a terminal CCA 3′.
