Glossary

Autotrophic methanogens utilize hydrogen as energy source for the reduction of [CO.sub.2] to methane; specialized genera of methanogens are also capable of inter- and intramolecular disproportionation of [C.sub.1] and [C.sub.2] carbon compounds (methanol, methylamines, acetate) to methane and CO2 (Boone et al., 1993).
