Snapshots of acetyl-CoA synthesis, the final step of CO2 fixation in the Wood-Ljungdahl pathway

bioRxiv
In the ancient microbial Wood-Ljungdahl pathway, CO2 is fixed in a multi-step process ending with acetyl-CoA synthesis at the bifunctional carbon monoxide dehydrogenase/acetyl-CoA synthase complex (CODH/ACS).

A Synthetic Acetyl-CoA Bi-cycle Synergizes the Wood-Ljungdahl Pathway for Efficient Carbon Conversion in Syngas Fermentation

, 2020
The Wood-Ljungdahl pathway (WLP) is a natural carbon fixation pathway capable of converting one-carbon (C1) compounds (CO2, CO, formate) to two-carbon (C2) metabolite acetyl-CoA or coordinating with canonical glycolysis to convert sugar feedstocks to ...

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

The emergence and early evolution of biological carbon-fixation.

PLoS Computational Biology, 2012
The fixation of CO₂ into living matter sustains all life on Earth, and embeds the biosphere within geochemistry. The six known chemical pathways used by extant organisms for this function are recognized to have overlaps, but their evolution is ...

Anaerobic Biohydrogenation of Isoprene by Acetobacterium wieringae Strain Y

mBio, 2022
Isoprene is a ubiquitously distributed, biogenic, and climate-active organic compound. Microbial isoprene degradation in oxic environments is fairly well understood; however, studies exploring anaerobic isoprene metabolism remain scarce, with no isolates

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

Chemoorganoautotrophic lifestyle of the anaerobic enrichment culture N47 growing on naphthalene

Communications Biology
In almost all respiratory organisms, organic substrates are degraded via catabolic processes to the central metabolite acetyl-CoA which is then oxidized to CO2 for energy metabolism or used as a building block for anabolism.

Genes for selenium dependent and independent formate dehydrogenase in the gut microbial communities of three lower, wood-feeding termites and a wood-feeding roach [PDF]

, 2011
The bacterial Wood-Ljungdahl pathway for CO_2-reductive acetogenesis is important for the nutritional mutualism occurring between wood-feeding insects and their hindgut microbiota. A key step in this pathway is the reduction of CO_2 to formate,

Artificial Photosynthesis Would Unify the Electricity-Carbohydrate-Hydrogen Cycle for Sustainability [PDF]

, 2010
Sustainable development requires balanced integration of four basic human needs – air (O2/CO2), water, food, and energy. To solve key challenges, such as CO2 fixation, electricity storage, food production, transportation fuel production, water ...
