Deconstructing Methanosarcina acetivorans into an acetogenic archaeon
Proceedings of the National Academy of Sciences, 2022 Significance The reductive acetyl-coenzyme A (acetyl-CoA) pathway is the only carbon fixation pathway that can also be used for energy conservation like it is known for acetogenic bacteria. In methanogenic archaea, this pathway is extended with one route toward acetyl-CoA formation for anabolism and another route toward methane ...

Energy Conservation in Acetogenic Bacteria [PDF]
Applied and Environmental Microbiology, 2003 The anaerobic way of life comprises a great metabolic diversity and, correspondingly, diversity of energy-generating mechanisms ([52][1]). The facultative anaerobes have a respiratory system that uses preferentially oxygen, but in the absence of oxygen and presence of alternative electron ...

Energy Conservation in the Acetogenic Bacterium Clostridium aceticum [PDF]
Microorganisms, 2021 In times of global warming caused by the extensive use of fossil fuels, the need to capture gaseous carbon compounds is growing bigger. Several groups of microorganisms can fix the greenhouse gas CO2. Out of these, acetogenic bacteria are role models in their ability to reduce CO2 with hydrogen to acetate, which makes acetogens prime candidates for ...

Engineered acetogenic bacteria as microbial cell factory for diversified biochemicals
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

Defining Genomic and Predicted Metabolic Features of the Acetobacterium Genus
mSystems, 2020 Acetogens are anaerobic bacteria capable of fixing CO2 or CO to produce acetyl coenzyme A (acetyl-CoA) and ultimately acetate using the Wood-Ljungdahl pathway (WLP).

CO Metabolism in the Acetogen Acetobacterium woodii [PDF]
Applied and Environmental Microbiology, 2015 ABSTRACT The Wood-Ljungdahl pathway allows acetogenic bacteria to grow on a number of one-carbon substrates, such as carbon dioxide, formate, methyl groups, or even carbon monoxide. Since carbon monoxide alone or in combination with hydrogen and carbon dioxide (synthesis gas) is an increasingly important feedstock for third ...

Sodium bioenergetics in methanogens and acetogens [PDF]
FEMS Microbiology Letters, 1990 Recent investigations with Methanosarcina barkeri elucidated the role of sodium ions in the energy metabolism of methanogenic bacteria and provided evidence for a novel mechanism of energy transduction with Na+ as the coupling ion. During methanogenesis from methanol, an eletrochemical sodium gradient generated by a Na+/H+ antiporter is used as the ...

Accelerate acetogenic bioproduction: Acetogens as sustainable producers of biocommodities
Current Opinion in Systems BiologyGas fermentation using autotrophic acetogenic bacteria has been industrialized, however, its full potential remains untapped, with only native products like ethanol being produced thus far. Advancements in synthetic biology have enabled the recombinant production of diverse biocommodities to broaden their limited natural product spectrum from C1-gases.
