Methanogenic pathways in Methanosphaera stadtmanae.


Methanosphaera stadtmanae reduces methanol to CH4 in a similar way as Methanosarcina barkeri. Low activities of 5,10-methylenetetrahydromethanopterin dehydrogenase (MTDH) and reductase (MTR) were found. From studies on formaldehyde oxidation and reduction it was concluded that most likely the inability to reduce CO2 to CH4 was due to the lack of an active… (More)
