Identification and Characterization of Oxalate Oxidoreductase, a Novel Thiamine Pyrophosphate-dependent 2-Oxoacid Oxidoreductase That Enables Anaerobic Growth on Oxalate [PDF]

, 2010
Moorella thermoacetica is an anaerobic acetogen, a class of bacteria that is found in the soil, the animal gastrointestinal tract, and the rumen. This organism engages the Wood-Ljungdahl pathway of anaerobic CO2 fixation for heterotrophic or autotrophic ...

Rapid Kinetic Studies of Acetyl-CoA Synthesis:  Evidence Supporting the Catalytic Intermediacy of a Paramagnetic NiFeC Species in the Autotrophic Wood−Ljungdahl Pathway^†

, 2016
CO dehydrogenase/acetyl-CoA synthase (CODH/ACS), a key enzyme in the Wood−Ljungdahl pathway of anaerobic CO2 fixation, is a bifunctional enzyme containing CODH, which catalyzes the reversible two-electron oxidation of CO to CO2, and ACS, which catalyzes ...

Clostridium autoethanogenum alters cofactor synthesis, redox metabolism, and lysine-acetylation in response to elevated H2:CO feedstock ratios for enhancing carbon capture efficiency

Biotechnology for Biofuels and Bioproducts
Background Clostridium autoethanogenum is an acetogenic bacterium that autotrophically converts carbon monoxide (CO) and carbon dioxide (CO2) gases into bioproducts and fuels via the Wood–Ljungdahl pathway (WLP).

Sugar-inducible promoters for manipulation of core metabolic pathways in the thermophilic acetogen Thermoanaerobacter kivui

Applied and Environmental Microbiology
Acetogenic bacteria form an essential part of the global carbon cycle and show promise for green chemicals production thanks to their energy-efficient carbon fixation via the Wood-Ljungdahl pathway. Energy conservation in acetogens is dependent on one of

Old Acetogens, New Light [PDF]

, 2008
Acetogens utilize the acetyl-CoA Wood-Ljungdahl pathway as a terminal electron-accepting, energy-conserving, CO2-fixing process. The decades of research to resolve the enzymology of this pathway (1) preceded studies demonstrating that acetogens not only ...

Formate-dependent growth and homoacetogenic fermentation by a bacterium from human feces: Description of Bryantella formatexigens gen. nov., sp nov. [PDF]

, 2003
Formate stimulates growth of a new bacterium from human feces. With high formate, it ferments glucose to acetate via the Wood-Ljungdahl pathway. The original isolate fermented vegetable cellulose and carboxymethylcellulose, but it lost this ability after
