1. In other words, these methanogens improve the coefficient of utilization. 2. Some methanogens have a cell wall that is composed of pseudopeptidoglycan. 3. Finally, methanogens convert these products to methane and carbon dioxide. 4. This disproportionation reaction is catalysed by methanogen archaea in their fermentative metabolism. 5. Another study has also discovered methanogens in a harsh environment on Earth. 6. All of these products can be used by autotrophic methanogens . 7. Methanogens are coccoid ( spherical shaped ) or bacilli ( rod shaped ).8. It is notable for being an extremely thermophilic methanogen . 9. Examples from modern biology are known where methanogens cluster around hydrogenosomes within eukaryotic cells. 10. Acetate and hydrogen produced in the first stages can be used directly by methanogens .
