The emergence and early evolution of biological carbon-fixation.

open access: yesPLoS 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 ...

Engineering Acetogenic Bacteria for Efficient One-Carbon Utilization

open access: yesFrontiers in Microbiology, 2022
C1 gases, including carbon dioxide (CO2) and carbon monoxide (CO), are major contributors to climate crisis. Numerous studies have been conducted to fix and recycle C1 gases in order to solve this problem.

Enzymatic Electrosynthesis for Sustainable CO2 Conversion: Advancing Circular Carbon Economy

open access: yesCarbon Energy, EarlyView.
Enzymatic electrosynthesis (EES) offers molecular precision in synthesizing value‐added products from CO2. We highlight its distinct edge over alternative enzyme‐hybrid systems and analyze electron transfer pathways. Key strategies to overcome electron transfer bottlenecks and expand product diversity are addressed, and also data‐driven approaches for ...

Gut Microbiota of Gray Snub‐Nosed Monkeys: Adaptation to Seasonal Variations Through Energy Compensation and Thermogenesis

open access: yesIntegrative Zoology, EarlyView.
Based on metagenome‐assembled genomes (MAGs), the gut microbiota of the gray snub‐nosed monkeys recovered 1229 non‐redundant MAGs. The gut microbiota showed an enhanced capacity to produce energy substrates with increased conversion activity of these substrates during winter.

Chemoorganoautotrophic lifestyle of the anaerobic enrichment culture N47 growing on naphthalene

open access: yesCommunications 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.

Anaerobic Biohydrogenation of Isoprene by Acetobacterium wieringae Strain Y

open access: yesmBio, 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

Short‐Chain Fatty Acids: Microbial Metabolites Driving Gut‐Eye Axis Signaling

open access: yesComprehensive Physiology, Volume 16, Issue 5, October 2026.
Short‐chain fatty acids generated by gut microbial fermentation link diet to ocular physiology via the gut–eye axis. Through systemic distribution, these metabolites regulate GPCR signaling, epigenetic pathways, inflammation, and angiogenesis, shaping retinal homeostasis and highlighting therapeutic potential in ocular vascular and inflammatory ...

An archaeal origin of the Wood-Ljungdahl H4MPT branch and the emergence of bacterial methylotrophy

open access: yes, 2019
International audienceThe tetrahydromethanopterin (H 4 MPT) methyl branch of the Wood-Ljungdahl pathway is shared by archaeal and bacterial metabolisms that greatly contribute to the global carbon budget and greenhouse gas fluxes: methanogenesis and ...

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the
