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 ...

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 ...

Biotransformations of aromatic aldehydes by acetogenic bacteria [PDF]
FEMS Microbiology Letters, 1990 Vanillin was subject to O demethylation and supported growth of Clostridium formicoaceticum and Clostridium thermoaceticum. Vanillin was also stimulatory to the CO-dependent growth of Peptostreptococcus productus. The aldehyde substituent of vanillin was metabolized by routes which were dependent upon both the acetogen and a co-metabolizable substrate (

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 ...

Frontiers in Microbiology, 2022 Hydrogen (H2) converted to reducing equivalents is used by acetogens to fix and metabolize carbon dioxide (CO2) to acetate. The utilization of H2 enables not only autotrophic growth, but also mixotrophic metabolism in acetogens, enhancing carbon ...

Acetogenic production of 3-Hydroxybutyrate using a native 3-Hydroxybutyryl-CoA Dehydrogenase
Frontiers in Microbiology, 2022 3-Hydroxybutyrate (3HB) is a product of interest as it is a precursor to the commercially produced bioplastic polyhydroxybutyrate. It can also serve as a platform for fine chemicals, medicines, and biofuels, making it a value-added product and feedstock.
