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.

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 ...

Structural Metabolic Modelling of the Acetogen Acetobacterium woodii [PDF]

open access: yes, 2020
Acetogens are microbes that produce acetate as a fermentation by-product from a diverse range of substrates including gaseous substrates. They achieve this by employing the Wood- Ljungdahl Pathway (WLP), which enables the xation of carbon dioxide into ...

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.

The pyruvate:ferredoxin oxidoreductase of the thermophilic acetogen, Thermoanaerobacter kivui

open access: yesFEBS Open Bio, 2021
Pyruvate:ferredoxin oxidoreductase (PFOR) is a key enzyme in bacterial anaerobic metabolism. Since a low‐potential ferredoxin (Fd2−) is used as electron carrier, PFOR allows for hydrogen evolution during heterotrophic growth as well as pyruvate synthesis

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.

Purification and characterization of a thermophilic NAD+‐dependent lactate dehydrogenase from Moorella thermoacetica

open access: yesFEBS Open Bio
Oxidation of lactate under anaerobic dark fermentative conditions poses an energetic problem. The redox potential of the lactate/pyruvate couple is too electropositive to reduce the physiological electron carriers NAD(P)+ or ferredoxin.

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 ...
