A Third Way of Energy Conservation in Acetogenic Bacteria
Microbiology Spectrum, 2022 Acetogenic bacteria are a group of strictly anaerobic bacteria that make a living from acetate formation from two molecules of CO2 via the Wood-Ljungdahl pathway (WLP).

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

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

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 ...

Adaptive Laboratory Evolution of Eubacterium limosum ATCC 8486 on Carbon Monoxide
Frontiers in Microbiology, 2020 Acetogens are naturally capable of metabolizing carbon monoxide (CO), a component of synthesis gas (syngas), for autotrophic growth in order to produce biomass and metabolites such as acetyl-CoA via the Wood–Ljungdahl pathway.

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,
