A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

Animal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

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.

Obligate autotrophy at the thermodynamic limit of life in a new acetogenic bacterium

Frontiers in Microbiology, 2023
One of the important current issues of bioenergetics is the establishment of the thermodynamic limits of life. There is still no final understanding of what is the minimum value of the energy yield of a reaction that is sufficient to be used by an ...

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.

Enrichment of Anaerobic Syngas-Converting Communities and Isolation of a Novel Carboxydotrophic Acetobacterium wieringae Strain JM

Frontiers in Microbiology, 2020
Syngas is a substrate for the anaerobic bioproduction of fuels and valuable chemicals. In this study, anaerobic sludge was used for microbial enrichments with synthetic syngas and acetate as main substrates.

Methanol Metabolism in the Cytochrome and Menaquinone‐Containing Acetogen Moorella thermoacetica

Environmental Microbiology, Volume 28, Issue 7, July 2026.
The thermophilic acetogenic bacterium Moorella thermoacetica is a promising platform organism to convert C1 compounds to valuable products. Gaseous C1 substrates are technically difficult to use for fermentation in an industrial scale, but methanol, which can be produced chemically from carbon dioxide, is a suitable alternative.

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

Advanced 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.
