MethanobacteriumRANK: GenusTAXONOMY: cellular organisms -> Archaea -> Euryarchaeota -> Methanobacteria -> Methanobacteriales -> Methanobacteriaceae -> Methanobacterium OVERVIEW: Methanobacteriaceae are a family of the Methanobacteriales. Has the ability to anaerobically produce methane through a process known as methanogenesis. The microorganism's metabolism is dictated via 2 processes: the Carbon Cycle and Alcohol Dehydrogenase enzyme. When following the Carbon Cycle pathway, carbon dioxide oxidizes hydrogen gas to produce methane and water. In this case, hydrogen gas is the electron donor and carbon dioxide is the electron acceptor. The alternate pathway, as stated above, utilizes an alcohol dehydrogenase enzyme to convert carbon dioxide and 2-propanol. This reaction produces the products methane and acetone. In this case, the hydrogens bound in the 2-propanol molecule are the electron donors and carbon dioxide is the electron acceptor. |
