Most methanogenic archaea can reduce CO2 with H2 to methane, and it is generally assumed that the reactions and mechanisms of energy conservation that are involved are largely the same in all… Expand
The review describes four flavin-containing cytoplasmatic multienzyme complexes from anaerobic bacteria and archaea that catalyze the reduction of the low potential ferredoxin by electron donors with… Expand
The assimilation of carbon dioxide (CO2) into organic material is quantitatively the most important biosynthetic process. We discovered that an autotrophic member of the archaeal order Sulfolobales,… Expand
Energy conservation in chemotrophic organisms is generally coupled to redox reactions in catabolic pathways. In the oxidative part or branch, “energy-rich” compounds are formed, from which ATP is… Expand
Cell extracts of butyrate-forming clostridia have been shown to catalyze acetyl-coenzyme A (acetyl-CoA)- and ferredoxin-dependent formation of H2 from NADH. It has been proposed that these bacteria… Expand
Clostridium kluyveri is unique among the clostridia; it grows anaerobically on ethanol and acetate as sole energy sources. Fermentation products are butyrate, caproate, and H2. We report here the… Expand
Escherichia coli grew in a minimal medium on propionate as the sole carbon and energy source. Initially a lag phase of 4–7 days was observed. Cells adapted to propionate still required 1–2 days… Expand
Propionate is used to protect bread and animal feed from moulds. The mode of action of this short-chain fatty acid was studied using Aspergillus nidulans as a model organism. The filamentous fungus… Expand
In Escherichia coli and Aspergillus nidulans, propionate is oxidized to pyruvate via the methylcitrate cycle. The last step of this cycle, the cleavage of 2-methylisocitrate to succinate and pyruvate… Expand
Acryloyl-CoA reductase from Clostridium propionicum catalyses the irreversible NADH-dependent formation of propionyl-CoA from acryloyl-CoA. Purification yielded a heterohexadecameric yellow-greenish… Expand
