Insight into the function and evolution of the Wood-Ljungdahl pathway in Actinobacteria. [PDF]
Abstract Carbon fixation by chemoautotrophic microbes such as homoacetogens had a major impact on the transition from the inorganic to the organic world. Recent reports have shown the presence of genes for key enzymes associated with the Wood–Ljungdahl pathway (WLP) in the phylum Actinobacteria, which adds to the diversity of potential ...

Potential for homoacetogenesis via the Wood-Ljungdahl pathway in Korarchaeia lineages from marine hydrothermal vents. [PDF]
Abstract The Wood–Ljungdahl pathway (WLP) is a key metabolic component of acetogenic bacteria where it acts as an electron sink. In Archaea, despite traditionally being linked to methanogenesis, the pathway has been found in several Thermoproteota and Asgardarchaeota lineages.

Genomic Insights into Syntrophic Lifestyle of 'Candidatus Contubernalis alkaliaceticus' Based on the Reversed Wood-Ljungdahl Pathway and Mechanism of Direct Electron Transfer. [PDF]
The anaerobic oxidation of fatty acids and alcohols occurs near the thermodynamic limit of life. This process is driven by syntrophic bacteria that oxidize fatty acids and/or alcohols, their syntrophic partners that consume the products of this oxidation, and the pathways for interspecies electron exchange via these products or direct interspecies ...

Methanogenesis and the Wood-Ljungdahl Pathway: An Ancient, Versatile, and Fragile Association. [PDF]
Methanogenesis coupled to the Wood-Ljungdahl pathway is one of the most ancient metabolisms for energy generation and carbon fixation in the Archaea. Recent results are sensibly changing our view on the diversity of methane-cycling capabilities in this Domain of Life.

Reduction, evolutionary pattern and positive selection of genes encoding formate dehydrogenase in Wood-Ljungdahl pathway of gastrointestinal acetogens suggests their adaptation to formate-rich habitats. [PDF]
Abstract Acetogens are anaerobes using Wood–Ljungdahl pathway (WLP) as the terminal electron acceptor for both assimilation and dissimilation of CO 2 and widely distributed in diverse habitats. However, their habitat adaptation is often unclear.

Enzymology of the wood-Ljungdahl pathway of acetogenesis. [PDF]
The biochemistry of acetogenesis is reviewed. The microbes that catalyze the reactions that are central to acetogenesis are described and the focus is on the enzymology of the process. These microbes play a key role in the global carbon cycle, producing over 10 trillion kilograms of acetic acid annually.

Acetogenesis and the Wood-Ljungdahl pathway of CO(2) fixation. [PDF]
Conceptually, the simplest way to synthesize an organic molecule is to construct it one carbon at a time. The Wood-Ljungdahl pathway of CO(2) fixation involves this type of stepwise process. The biochemical events that underlie the condensation of two one-carbon units to form the two-carbon compound, acetate, have intrigued chemists, biochemists, and ...

Wood-Ljungdahl pathway utilisation during in situ H2 biomethanation [PDF]
Biogas production from organic waste is a waste-to-energy technology with the potential to contribute significantly to sustainable energy production. Upgrading of biogas using in situ biomethanation with hydrogen has the potential for surplus electricity storage, and delivery of biogas with a methane content of >90%, allowing for easier integration ...

Diverse Energy-Conserving Pathways in Clostridium difficile: Growth in the Absence of Amino Acid Stickland Acceptors and the Role of the Wood-Ljungdahl Pathway. [PDF]
Clostridium difficile is an anaerobic, multidrug-resistant, toxin-producing pathogen with major health impacts worldwide. It is the only widespread pathogen harboring a complete set of Wood-Ljungdahl pathway (WLP) genes; however, the role of the WLP in C. difficile is poorly understood.

Bacterial estrogenesis without oxygen: Wood-Ljungdahl pathway likely contributed to the emergence of estrogens in the biosphere. [PDF]
Androgen and estrogen, key sex hormones, were long thought to be exclusively produced by vertebrates. The O 2 -dependent aromatase that converts androgen to estrogen (estrogenesis) has never been identified in any prokaryotes. Here, we report the finding of anaerobic estrogenesis in a Peptococcaceae bacterium (
