Enzymatic Electrosynthesis for Sustainable CO2 Conversion: Advancing Circular Carbon Economy

Carbon 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 ...

Interconnection of methanogenic and acetogenic pathways [PDF]

FEMS Microbiology Letters, 1983
Methanopterin displays a folate-like biochemistry: methenyl-, methylene- and methyltetrahydromethanopterin are intermediates in the process of methanogenesis. A corrinoid-enzyme is involved in methanol conversion and the possible function of such enzymes in cell-carbon synthesis and acetate conversion is discussed.

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

A Pore or not a Pore? Understanding Pore Size Distributions of Non‐Graphitic Carbon and Atomically‐Dispersed M‐N‐C Materials

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Gassorption analysis of in‐plane functionalized carbons reveals small, uniform ultramicropore signatures as potential artefacts of specific adsorption of the probe gases. Low‐pressure Langmuir fitting links these features to distinct functionalities via adsorption energies, enabling straightforward quantification of otherwise inaccessible surface‐site ...

Physiology of the thermophilic acetogen Moorella thermoacetica

Research in Microbiology, 2004
Moorella thermoacetica (originally isolated as Clostridium thermoaceticum) has served as the primary acetogenic bacterium for the resolution of the acetyl coenzyme A (acetyl-CoA) or Wood-Ljungdahl pathway, a metabolic pathway that (i) autotrophically assimilates CO2 and (ii) is centrally important to the turnover of carbon in many habitats. The purpose

Formate Is Required for Growth of the Thermophilic Acetogenic Bacterium Thermoanaerobacter kivui Lacking Hydrogen-Dependent Carbon Dioxide Reductase (HDCR)

Frontiers in Microbiology, 2020
The hydrogen-dependent carbon dioxide reductase is a soluble enzyme complex that directly utilizes hydrogen (H2) for the reduction of carbon dioxide (CO2) to formate in the first step of the acetyl-coenzyme A- or Wood-Ljungdahl pathway (WLP).

Cobalamin‐Dependent O‐Demethylation of Polymethoxyflavones by Enzymes Isolated From the Human Gut Microorganism Blautia producta MRG‐PMF1

Advanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
O‐demethylation of aryl methyl ethers is an invaluable transformation, playing a critical role in ecological circulation by degrading abundant lignin‐derived compounds and other natural products. Chemical O‐demethylation requires harsh reaction conditions; thus, the need for biocatalytic solutions is of high interest.
