Abstract
Autotrophic methanogens reduce CO2 to CO and assimilate CO in a carbonylation reaction. Heterotrophic species were found not to form CO and/or to incorporate CO into cell matiral. The absence of CO formation correlated with the absence of carbon monoxide dehydrogenase activity. The heterotrophic Methanobrevibacter ruminantium, Methanobrevibacter smithii, Methanococcus voltae and Methanospirillum hungatei (strain GP 1) were investigated.
