Analysis of the core genome and pan-genome of autotrophic acetogenic bacteria

Frontiers in Microbiology, 2016
Acetogens are obligate anaerobic bacteria capable of reducing carbon dioxide (CO2) to multicarbon compounds coupled to the oxidation of inorganic substrates, such as hydrogen (H2) or carbon monoxide (CO), via the Wood-Ljungdahl pathway.

Enhancing methane production from food waste fermentate using biochar. The added value of electrochemical testing in pre-selecting the most effective type of biochar [PDF]

, 2017
Background: Recent studies have suggested that addition of electrically conductive biochar particles is an effective strategy to improve the methanogenic conversion of waste organic substrates, by promoting syntrophic associations between acetogenic and ...

Assessment of Chemical Inhibitor Addition to Improve the Gas Production from Biowaste [PDF]

, 2019
The coexistence of sulphate-reducing bacteria and methanogenic archaea in the reactors during the anaerobic digestion from sulphate-containing waste could favor the accumulation of sulfide on the biogas, and therefore reduce its quality.

Adaptive laboratory evolution of a thermophile toward a reduced growth temperature optimum

Frontiers in Microbiology, 2023
Thermophily is an ancient trait among microorganisms. The molecular principles to sustain high temperatures, however, are often described as adaptations, somewhat implying that they evolved from a non-thermophilic background and that thermophiles, i.e ...

Surface Analysis of Coal Indicating Neutral Red Enhances the Precursor Steps of Methanogenesis

Frontiers in Microbiology, 2020
Artificially stimulated, high-yield microbial production of methane from coal is a challenging problem that continues to generate research interest. Decomposition of organic matter and production of methane from coal are the results of multiple redox ...

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).

Methanogen Levels Are Significantly Associated with Fecal Microbiota Composition and Alpha Diversity in Healthy Adults and Irritable Bowel Syndrome Patients

Microbiology Spectrum, 2022
Hydrogenotrophic microbes, primarily including the three functional groups methanogens, sulfate-reducing bacteria, and reductive acetogens, use hydrogen as an energy source and play an important role in maintaining the hydrogen balance in gut ecosystems.

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
