Acetogen Communities in the Gut of Herbivores and Their Potential Role in Syngas Fermentation

Fermentation, 2018
To better understand the effects of host selection on gut acetogens and their potential role in syngas fermentation, the composition and hydrogenotrophic features of acetogen populations in cow and sheep rumens, rabbit ceca, and horse feces were studied.

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).

Comparative Microbiome Analysis Reveals the Ecological Relationships Between Rumen Methanogens, Acetogens, and Their Hosts

Frontiers in Microbiology, 2020
Ruminant methane, which is generated by methanogens through the consumption of hydrogen and supports the normal function of the rumen ecosystem, is a major source of greenhouse gases.

Genome-Scale Analysis of Acetobacterium woodii Identifies Translational Regulation of Acetogenesis

mSystems, 2021
Acetogens synthesize acetyl-CoA via the CO2-fixing Wood-Ljungdahl pathway. Despite their ecological and biotechnological importance, their translational regulation of carbon and energy metabolisms remains unclear.

A fluorescent reporter system for anaerobic thermophiles

Frontiers in Bioengineering and Biotechnology, 2023
Owing to their inherent capacity to make invisible biological processes visible and quantifiable, fluorescent reporter systems have numerous applications in biotechnology. For classical fluorescent protein systems (i.e., GFP and derivatives), chromophore

How formate dehydrogenase-lacking acetogen Clostridium bovifaecis utilize formate as the sole carbon source for its acetogenic growth?

bioRxiv, 2023
Little is known about the growth of formate dehydrogenase-lacking acetogen on formate as sole carbon source. Here, we analyzed formate metabolism in Clostridium bovifaecis strain BXX using different concentrations of formate.
