, 1987 Acetogenic bacteria are strictly anaerobic eubacteria which catalyze the formation of acetate from CO2 in their energy metabolism. The CO2 reduction to acetate can serve as an electron sink for reducing equivalents generated during oxidative degradation of carbohydrates and various other substrates. However, acetate synthesis from CO2 is also the major

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen. [PDF]
FEBS JSerpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

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

Genomic and Transcriptomic Insights Into the Autotrophic Metabolism on H<sub>2</sub> + CO<sub>2</sub> or CO of the Thermophilic Acetogenic Model Organism Moorella thermoacetica. [PDF]
Environ MicrobiolMoorella thermoacetica is the model organism for elucidation of acetogenesis. The reduction of CO2 to acetate is well studied, but how redox carrier balancing and energy conservation are maintained during autotrophic growth and how H2 is oxidised remains enigmatic.

Metabolic versatility enables acetogens to colonize ruminants with diet-driven niche partitioning. [PDF]
ISME JEnteric methane emissions are energy losses from farmed ruminants and contribute to global warming. Diverting electrons and H2 flow toward beneficial fermentation products would mitigate ruminal methane emissions while improving feed efficiency ...

Data_Sheet_1_The root zone of graminoids: A niche for H2-consuming acetogens in a minerotrophic peatland.docx [PDF]
, 2022 The importance of acetogens for H2 turnover and overall anaerobic degradation in peatlands remains elusive. In the well-studied minerotrophic peatland fen Schlöppnerbrunnen, H2-consuming acetogens are conceptualized to be largely outcompeted by iron ...
