Effect of Humin and Chemical Factors on CO2-Fixing Acetogenesis and Methanogenesis [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2022
Acetogenesis and methanogenesis have attracted attention as CO2-fixing reactions. Humin, a humic substance insoluble at any pH, has been found to assist CO2-fixing acetogenesis as the sole electron donor. Here, using two CO2-fixing consortia with acetogenic and methanogenic activities, the effect of various parameters on these activities was examined ...

Humin Assists Reductive Acetogenesis in Absence of Other External Electron Donor [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2020
The utilization of extracellular electron transfer by microorganism is highly engaging for remediation of toxic pollutants under “energy-starved” conditions. Humin, an organo-mineral complex of soil, has been instrumental as an external electron mediator for suitable electron donors in the remediative works of reductive dehalogenation, denitrification,

Potential Contribution of Acetogenesis to Anaerobic Degradation in Methanogenic Rice Field Soils

open access: yesSoil Biology and Biochemistry, 2018
Acetate is an important intermediate in the anaerobic degradation of organic matter. It is not only produced by fermentation but also by the reduction of CO2 via the acetyl-CoA pathway (acetogenesis).

New Insight Into Waste Activated Sludge Acetogenesis Triggered by Coupling Sulfite/Ferrate Oxidation With Sulfate Reduction-Mediated Syntrophic Consortia

open access: yesChemical Engineering Journal, 2020
Acetate (HAc) production via acetogenesis is a promising biorefinery approachfor waste activated sludge (WAS); however, it is hampered by the thermodynamicconstraints of the bioconversion of 3-5 carbon atom short-chain fatty acids (SCFAs).

Acetogenesis and the Wood–Ljungdahl Pathway of CO2 Fixation [PDF]

open access: yesBiochimica Et Biophysica Acta - Proteins and Proteomics, 2008
Conceptually, the simplest way to synthesize an organic molecule is to construct it one carbon at a time. The Wood-Ljungdahl pathway of CO(2) fixation involves this type of stepwise process. The biochemical events that underlie the condensation of two one-carbon units to form the two-carbon compound, acetate, have intrigued chemists, biochemists, and ...

Acetogen and acetogenesis for biological syngas valorization

Bioresource Technology, 2023
The bioconversion of syngas using (homo)acetogens as biocatalysts shows promise as a viable option due to its higher selectivity and milder reaction conditions compared to thermochemical conversion. The current bioconversion process operates primarily to produce C2 chemicals (e.g., acetate and ethanol) with sufficient technology readiness levels (TRLs)
