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

open access: yesAdvanced 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 ...

CO Metabolism in the Thermophilic Acetogen Thermoanaerobacter kivui [PDF]

open access: yesApplied and Environmental Microbiology, 2016
ABSTRACT The thermophilic acetogenic bacterium Thermoanaerobacter kivui , previously described not to use carbon monoxide as a carbon and energy source, was adapted to grow on CO. This was achieved by using a preculture grown on H 2 plus CO 2 and by ...

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

open access: yesAdvanced 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.

Adaptation of the acetogen Clostridium thermoautotrophicum to minimal medium [PDF]

open access: yesJournal of Bacteriology, 1986
Clostridium thermoautotrophicum was adapted to minimal medium and cultivated at the expense of glucose, methanol, or H2-CO2. No supplemental amino acids were required for growth of the adapted strain, and nicotinic acid was the sole essential vitamin.

Production of the biocommodities butanol and acetone from methanol with fluorescent FAST-tagged proteins using metabolically engineered strains of Eubacterium limosum

open access: yesBiotechnology for Biofuels, 2021
Background The interest in using methanol as a substrate to cultivate acetogens increased in recent years since it can be sustainably produced from syngas and has the additional benefit of reducing greenhouse gas emissions.

A TetR-family protein (CAETHG_0459) activates transcription from a new promoter motif associated with essential genes for autotrophic growth in acetogens

open access: yes, 2019
Acetogens can fix carbon (CO or CO2) into acetyl-CoA via the Wood-Ljungdahl pathway (WLP) that also makes them attractive cell factories for the production of fuels and chemicals from waste feedstocks.

Bridging Liquid and Gas Phase Catalysis for Abiotic CO2 Conversion to Prebiotic Organics Over Mesoporous Silica‐Supported Ni–Co Catalysts

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Under simulated hydrothermal vent conditions, Ni⋅Co bimetallic catalysts supported on silica convert CO2 and H2O into key metabolites such as formate, methanol, and ethanol. Water plays a critical role in CO2 adsorption and product selectivity, shaping catalytic performance across both liquid and gas phases.

A Comprehensive Review of the Key Factors Affecting Biogas Production From Anaerobic Digestion of Organic Waste

open access: yesCleanMat, Volume 3, Issue 2, Page 74-98, June 2026.
Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...
