Pathways and bioenergetics of anaerobic carbon monoxide fermentation.

Frontiers in Microbiology, 2015
Carbon monoxide can act as a substrate for different modes of fermentative anaerobic metabolism. The trait of utilizing CO is spread among a diverse group of microorganisms, including members of bacteria as well as archaea.

Early matrine intervention of gut microbiota for type 2 diabetes prevention

iMetaOmics, EarlyView.
How matrine influences gut microbiota imbalance to prevent the progression of diabetes remains unclear. We conduct experiments using mice to simulate the stages of diabetes development and matrine intervention. Combined with amplicon sequencing, we find that the gut microbiota of diabetic mice continuously changes with the progression of the disease ...

Functional gene analysis suggests different acetogen populations in the Bovine Rumen and Tammar Wallaby Forestomach [PDF]

, 2010
Reductive acetogenesis via the acetyl coenzyme A (acetyl-CoA) pathway is an alternative hydrogen sink to methanogenesis in the rumen. Functional gene-based analysis is the ideal approach for investigating organisms capable of this metabolism (acetogens).

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Relative contributions of carbohydrates and proteins to metal mobilisation in an anaerobic soil slurry amended with rum vinasses [PDF]

, 2004
The spreading of liquid organic wastes on soils enhances the risks of anaerobiosis and metal mobilisation. Under anaerobiosis, microbial activities drive most of soil geochemical evolutions through reductions, pH changes, net production of mineral and ...

A Cytochrome c‐Containing Periplasmic Nitrate Reductase in the Acetogen Sporomusa ovata

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Sporomusa ovata, a cytochrome‐containing, acetogenic bacterium, conserves energy by reduction of carbon dioxide to acetate. Nitrate serves as additional electron acceptor and is reduced to ammonium, resulting in increased growth and reduced acetate production.

CO2 supply is a powerful tool to control homoacetogenesis, chain elongation and solventogenesis in ethanol and carboxylate fed reactor microbiomes

Frontiers in Bioengineering and Biotechnology
Anaerobic fermentation technology enables the production of medium chain carboxylates and alcohols through microbial chain elongation. This involves steering reactor microbiomes to yield desired products, with CO2 supply playing a crucial role in ...

Microbiomes in Soils Exposed to Naturally High Concentrations of CO2 (Bossoleto Mofette Tuscany, Italy)

Frontiers in Microbiology, 2019
Direct and indirect effects of extremely high geogenic CO2 levels, commonly occurring in volcanic and hydrothermal environments, on biogeochemical processes in soil are poorly understood.
