Amino acid metabolism of the thermophilic acetogen Thermacetogenium phaeum. [PDF]

PLoS ONE
Anaerobic microbial degradation of the amino acids glycine and serine either occurs through enzymes of the so-called Stickland reaction or alternatively through the glycine cleavage system (GCS).

Methanol Metabolism in the Cytochrome and Menaquinone-Containing Acetogen Moorella thermoacetica. [PDF]

Environ Microbiol
The thermophilic acetogenic bacterium Moorella thermoacetica is a promising platform organism to convert C1 compounds to valuable products. Gaseous C1 substrates are technically difficult to use for fermentation in an industrial scale, but methanol, which can be produced chemically from carbon dioxide, is a suitable alternative.

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.

Mutual Metabolic Interactions in Co-cultures of the Intestinal Anaerostipes rhamnosivorans With an Acetogen, Methanogen, or Pectin-Degrader Affecting Butyrate Production [PDF]

Frontiers in Microbiology, 2019
The human intestinal tract harbors diverse and complex microbial communities that have a vast metabolic capacity including the breakdown of complex carbohydrates into short chain fatty acids, acetate, propionate, and butyrate.

Physiology of the thermophilic acetogen Moorella thermoacetica [PDF]

Research in Microbiology, 2004
Moorella thermoacetica (originally isolated as Clostridium thermoaceticum) has served as the primary acetogenic bacterium for the resolution of the acetyl coenzyme A (acetyl-CoA) or Wood-Ljungdahl pathway, a metabolic pathway that (i) autotrophically assimilates CO2 and (ii) is centrally important to the turnover of carbon in many habitats. The purpose

Sporulation in solventogenic and acetogenic clostridia [PDF]

Applied Microbiology and Biotechnology, 2021
AbstractThe Clostridium genus harbors compelling organisms for biotechnological production processes; while acetogenic clostridia can fix C1-compounds to produce acetate and ethanol, solventogenic clostridia can utilize a wide range of carbon sources to produce commercially valuable carboxylic acids, alcohols, and ketones by fermentation. Despite their

Isobutanol Production by Autotrophic Acetogenic Bacteria [PDF]

Frontiers in Bioengineering and Biotechnology, 2021
Two different isobutanol synthesis pathways were cloned into and expressed in the two model acetogenic bacteria Acetobacterium woodii and Clostridium ljungdahlii. A. woodii is specialized on using CO2 + H2 gas mixtures for growth and depends on sodium ions for ATP generation by a respective ATPase and Rnf system. On the other hand, C. ljungdahlii grows

Clostridium autoethanogenum isopropanol production via native plasmid pCA replicon

Frontiers in Bioengineering and Biotechnology, 2022
Clostridium autoethanogenum is a model gas-fermenting acetogen for commercial ethanol production. It is also a platform organism being developed for the carbon-negative production of acetone and isopropanol by gas fermentation. We have assembled a 5.5 kb

Screening of Gas Substrate and Medium Effects on 2,3-Butanediol Production with C. ljungdahlii and C. autoethanogenum Aided by Improved Autotrophic Cultivation Technique

Fermentation, 2021
Gas fermentation by acetogens of the genus Clostridium is an attractive technology since it affords the production of biochemicals and biofuels from industrial waste gases while contributing to mitigate the carbon cycle alterations.
