Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

Advanced Science, Volume 13, Issue 17, 23 March 2026.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Molecular evolution of the Wood-Ljungdahl pathway and the reductive glycine pathway in Thermodesulfobacteriota

Abstract Carbon fixation is a fundamental metabolic process that sustains ecosystems, yet its origins and evolutionary history remain largely unresolved. In this study, we focused on the Wood-Ljungdahl (WL) pathway, which is considered one of the most ancient carbon fixation pathways and the reductive glycine (rGly) pathway, which ...

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

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 591-605, March/April 2026.
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

Assessing environmental gradients in relation to dark CO2 fixation in estuarine wetland microbiomes

Applied and Environmental Microbiology
The rising atmospheric concentration of CO2 is a major concern to society due to its global warming potential. In soils, CO2-fixing microorganisms are preventing some of the CO2 from entering the atmosphere.

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).

Direct carbon monoxide fixation via the bacterial and archaeal Wood–Ljungdahl pathways

Abstract The Wood–Ljungdahl (WL) pathway, which is widely distributed in both archaea and bacteria, is an ancient carbon fixation pathway from CO 2 . CO 2 fixation proceeds via two branches of pathway: progressive reduction to the methyl group in ...
