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 ...

Atypical one-carbon metabolism of an acetogenic and hydrogenogenic Moorella thermoacetica strain [PDF]
, 2009 A thermophilic spore-forming bacterium (strain AMP) was isolated from a thermophilic methanogenic bioreactor that was fed with cobalt-deprived synthetic medium containing methanol as substrate.

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.

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 ...

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.

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 ...
