Methanogenesis and the Wood–Ljungdahl Pathway: An Ancient, Versatile, and Fragile Association [PDF]

Genome Biology and Evolution, 2016
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.

Wood-Ljungdahl pathway utilisation during in situ H2 biomethanation [PDF]

Science of the Total Environment, 2022
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 ...

Genomic Insights into Syntrophic Lifestyle of ‘Candidatus Contubernalis alkaliaceticus’ Based on the Reversed Wood–Ljungdahl Pathway and Mechanism of Direct Electron Transfer [PDF]

Life, 2023
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 ...

Acetogenesis and the Wood–Ljungdahl pathway of CO2 fixation [PDF]

Biochimica Et Biophysica Acta - Proteins and Proteomics, 2008
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 ...

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]

Journal of Bacteriology, 2020
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]

Proceedings of the National Academy of Sciences of the United States of America
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.

Metalloproteins/metalloenzymes for the synthesis of acetyl-CoA in the Wood-Ljungdahl pathway

Science in China Series B: Chemistry, 2009
This paper focuses on the group of metalloproteins/metalloenzymes in the acetyl-coenzyme A synthesis pathway of anaerobic microbes called Wood-Ljungdahl pathway, including formate dehydrogenase (FDH), corrinoid iron sulfur protein (CoFeSP), acetyl-CoA synthase (ACS) and CO dehydrogenase (CODH).

Efforts to install a heterologous Wood-Ljungdahl pathway in Clostridium acetobutylicum enable the identification of the native tetrahydrofolate (THF) cycle and result in early induction of solvents

Metabolic Engineering, 2023
Here, we report the construction of a Clostridium acetobutylicum strain ATCC 824 (pCD07239) by heterologous expression of carbonyl branch genes (CD630_0723∼CD630_0729) from Clostridium difficile, aimed at installing a heterologous Wood-Ljungdahl pathway (WLP).

The Eastern and Western branches of the Wood/Ljungdahl pathway: how the East and West were won

BioFactors, 1997
Figure 1 is a transmission electron micrograph of Clostridium ljungdahlii [1]. It, like Acetobacterium woodii [2], was named after someone who made great contributions to the understanding of how anaerobes fix carbon dioxide. C. ljungdahlii was named after Lars Ljungdahl; A. woodii after Harland Wood. I had the good fortune to train under both Lars and

Exergy-based performance analysis of a continuous stirred bioreactor for ethanol and acetate fermentation from syngas via Wood–Ljungdahl pathway

Chemical Engineering Science, 2016
Abstract In this work, a thermodynamic framework was proposed to achieve improved process understanding of ethanol and acetate fermentation in a continuous stirred tank bioreactor from syngas through the Wood–Ljungdahl pathway. The bioreactor performance was evaluated using both conventional exergy and eco-exergy principles to identify the effect of ...
