Quantitative analysis of tetrahydrofolate metabolites from clostridium autoethanogenum

, 2018
Introduction quantification of tetrahydrofolates (THFs), important metabolites in the wood-Ljungdahl pathway (WLP) of acetogens, is challenging given their sensitivity to ...

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

Environmental 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

Mitigating methane emissions and promoting acetogenesis in ruminant livestock

Frontiers in Animal Science
Through enteric fermentation, ruminants convert fibrous biomass into high-quality proteins like meat and milk. In this process however, methanogenic archaea in the ruminant gastrointestinal tract produce methane, a potent greenhouse gas, from the by ...

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

, 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 ...

Effects of Bifidobacterium animalis Subsp. Lactis CP‐9 on Gut Microbiota and Immune Functions in Healthy Infants

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
This study evaluated the 3‐month safety and tolerability of the probiotic CP‐9 in healthy infants aged 6 to 36 months. The research confirmed that, under the conditions of this study, CP‐9 can safely enrich specific beneficial bacterium in the gut without any obvious short‐term safety signal. ABSTRACT Infancy represents a critical period for growth and

A TetR-Family Protein (CAETHG_0459) Activates Transcription From a New Promoter Motif Associated With Essential Genes for Autotrophic Growth in Acetogens

Frontiers in Microbiology, 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.

In Vivo Enzyme Catalytic Rates in Formate‐Growing Methanococcus maripaludis

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
In vivo catalytic rates of Methanococcus maripaludis enzymes during C1 carbon source limited growth were determined from metabolic model estimated fluxes and proteomics data. They showed weak agreement with turnover numbers predicted from sequences.

Epigenetic Perspectives on Maternal Gut Microbiota's Impact on Embryonic and Fetal Development

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review summarizes how maternal health and nutrition shape gut microbiota via epigenetics to regulate embryonic development. It highlights microbiota‐embryo interactions, disruption by prenatal chemical exposures, and personalized nutrition for disease prevention, offering novel insights and therapeutic targets.

Assessing environmental gradients in relation to dark CO2 fixation in estuarine wetland microbiomes

Applied and Environmental Microbiology
The rising atmospheric concentration of CO2 is a major concern to society due to its global warming potential. In soils, CO2-fixing microorganisms are preventing some of the CO2 from entering the atmosphere.
