Homo-Acetogens: Their Metabolism and Competitive Relationship with Hydrogenotrophic Methanogens
Microorganisms, 2022 Homo-acetogens are microbes that have the ability to grow on gaseous substrates such as H2/CO2/CO and produce acetic acid as the main product of their metabolism through a metabolic process called reductive acetogenesis.

Engineered acetogenic bacteria as microbial cell factory for diversified biochemicals [PDF]
Frontiers in Bioengineering and BiotechnologyAcetogenic bacteria (acetogens) are a class of microorganisms with conserved Wood-Ljungdahl pathway that can utilize CO and CO2/H2 as carbon source for autotrophic growth and convert these substrates to acetate and ethanol. Acetogens have great potential

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.

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,
