Genome-Scale Mining of Acetogens of the Genus Clostridium Unveils Distinctive Traits in [FeFe]- and [NiFe]-Hydrogenase Content and Maturation [PDF]
, 2022 Knowledge of the organizational and functional properties of hydrogen metabolism is pivotal to the construction of a framework supportive of a hydrogen-fueled low-carbon economy. Hydrogen metabolism relies on the mechanism of action of hydrogenases.

Reprogramming the metabolism of an acetogenic bacterium to homoformatogenesis
The ISME Journal, 2023 Abstract Methyl groups are abundant in anoxic environments and their utilization as carbon and energy sources by microorganisms involves oxidation of the methyl groups to CO2, followed by transfer of the electrons to an acceptor. In acetogenic bacteria, the electron acceptor is CO2 that is reduced to enzyme bound carbon monoxide, the ...

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).

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 ...

Baltic Sea methanogens compete with acetogens for electrons from metallic iron [PDF]
, 2019 Microbially induced corrosion of metallic iron (Fe0)-containing structures is an environmental and economic hazard. Methanogens are abundant in low-sulfide environments and yet their specific role in Fe0 corrosion is poorly understood.

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 ...

Physiology, phylogeny, and LUCA
Microbial Cell, 2016 Genomes record their own history. But if we want to look all the way back to life’s beginnings some 4 billion years ago, the record of microbial evolution that is preserved in prokaryotic genomes is not easy to read. Microbiology has a lot in common with

Surface Analysis of Coal Indicating Neutral Red Enhances the Precursor Steps of Methanogenesis
Frontiers in Microbiology, 2020 Artificially stimulated, high-yield microbial production of methane from coal is a challenging problem that continues to generate research interest. Decomposition of organic matter and production of methane from coal are the results of multiple redox ...
