Deletion of genes linked to the C1-fixing gene cluster affects growth, by-products, and proteome of Clostridium autoethanogenum

Frontiers in Bioengineering and Biotechnology, 2023
Gas fermentation has emerged as a sustainable route to produce fuels and chemicals by recycling inexpensive one-carbon (C1) feedstocks from gaseous and solid waste using gas-fermenting microbes.

Genome-Scale Mining of Acetogens of the Genus Clostridium Unveils Distinctive Traits in [FeFe]- and [NiFe]-Hydrogenase Content and Maturation

Microbiology Spectrum, 2022
Knowledge of the organizational and functional properties of hydrogen metabolism is pivotal to the construction of a framework supportive of a hydrogen-fueled low-carbon economy. Hydrogen metabolism relies on the mechanism of action of hydrogenases.

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.

Genome Sequence of Eubacterium limosum B2 and Evolution for Growth on a Mineral Medium with Methanol and CO₂ as Sole Carbon Sources

Microorganisms, 2022
Eubacterium limosum is an acetogen that can produce butyrate along with acetate as the main fermentation end-product from methanol, a promising C1 feedstock. Although physiological characterization of E.

Formate-Dependent Acetogenic Utilization of Glucose by the Fecal Acetogen Clostridium bovifaecis

Applied and Environmental Microbiology, 2020
The acetyl-CoA pathway is an ancient pathway of CO 2 fixation, which converts 2 mol of CO 2 into acetyl-CoA. Autotrophic growth with H 2 and CO 2 via the acetyl-CoA pathway as the terminal electron accepting process is the most unique feature of

Energetics and Application of Heterotrophy in Acetogenic Bacteria [PDF]

Applied and Environmental Microbiology, 2016
ABSTRACTAcetogenic bacteria are a diverse group of strictly anaerobic bacteria that utilize the Wood-Ljungdahl pathway for CO2fixation and energy conservation. These microorganisms play an important part in the global carbon cycle and are a key component of the anaerobic food web.

Comparative Analysis of the Microbiota Between Sheep Rumen and Rabbit Cecum Provides New Insight Into Their Differential Methane Production

Frontiers in Microbiology, 2018
The rumen and the hindgut represent two different fermentation organs in herbivorous mammals, with the former producing much more methane than the latter.

There Must be an Acetogen Somewhere [PDF]

Frontiers in Microbiology, 2012
In the beginning of 1983, when I was a post-doctoral student at the University of Illinois, Ralph Wolfe handed me an offprint of a long article and said: “Read this!” That paper was the review by Thauer et al. (1977) on “Energy conservation in chemotrophic anaerobic bacteria.” I have read it many times.

Genomic and in-situ Transcriptomic Characterization of the Candidate Phylum NPL-UPL2 From Highly Alkaline Highly Reducing Serpentinized Groundwater

Frontiers in Microbiology, 2018
Serpentinization is a process whereby water interacts with reduced mantle rock called peridotite to produce a new suite of minerals (e.g., serpentine), a highly alkaline fluid, and hydrogen. In previous reports, we identified abundance of microbes of the

Competition for Hydrogen Prevents Coexistence of Human Gastrointestinal Hydrogenotrophs in Continuous Culture

Frontiers in Microbiology, 2020
Understanding the metabolic dynamics of the human gastrointestinal tract (GIT) microbiota is of growing importance as research continues to link the microbiome to host health status.
