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).

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

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 ...

Mechanisms behind the impacts of CO2 concentration on microbial methanogenesis in coal seams

Meitian dizhi yu kantan
Background Coal seams exhibit the extensive distribution of a variety of indigenous functional microorganisms. Among these, some archaea enable methane metabolism using CO2 as a substrate, providing the potential for the biological CO2 storage and ...

Snapshots of acetyl-CoA synthesis, the final step of CO ₂ fixation in the Wood-Ljungdahl pathway

ABSTRACT In the ancient microbial Wood-Ljungdahl pathway, CO 2 is fixed in a multi-step process ending with acetyl-CoA synthesis at the bifunctional carbon monoxide dehydrogenase/acetyl-CoA synthase complex (CODH/ACS).

Asgard archaea modulate potential methanogenesis substrates in wetland soil

Nature Communications
The roles of Asgard archaea in eukaryogenesis and marine biogeochemical cycles are well studied, yet their contributions in soil ecosystems remain unknown. Of particular interest are Asgard archaeal contributions to methane cycling in wetland soils.
