An ecological and physiological study on acetogenesis as an alternative to methanogenesis in the rumen

, 1997
Methanogenesis is a predominant fermentation reaction in the gut ecosystem of ruminants. A functional replacement of methanogenesis with acetogenesis in the rumen could potentially decrease energy losses and increase the efficiency of ruminant production.

Chemical characterization of municipal wastewater sludges produced by two-phase anaerobic digestion for biogas production

, 2010
In the present study, the chemical features of municipal wastewater sludges treated in two-phase separate digesters (one for acetogenesis and the other one for methanogenesis), were characterized by using chemical analysis, stable carbon isotope ratios (&

Does acetogenesis really require especially low reduction potential?

, 2013
Acetogenesis is one of the oldest metabolic processes on Earth, and still has a major global significance. In this process, acetate is produced via the reduction and condensation of two carbon dioxide molecules. It has long been assumed that acetogenesis

Methanol metabolism in the acetogenic bacterium Acetobacterium woodii

, 2018
Methanol derived from plant tissue is ubiquitous in anaerobic sediments and a good substrate for anaerobes growing on C1 compounds such as methanogens and acetogens.

Syntrophic Jiont of Sulfate-Reducing Bacteria and Hydrogen-Producing Acetogen Stimulated Methane Production from Waste Activated Sludge Digestion

Fermentation
Anaerobic digestion of waste-activated sludge (WAS) towards biogas recovery is constrained by the limited hydrolysis and inhibited acetogenesis steps that hinder subsequent energy recovery.

Localization and in situ activities of homoacetogenic bacteria in the highly compartmentalized hindgut of soil-feeding higher termites (Cubitermes spp.)

, 1999
Methanogenesis and homoacetogenesis occur simultaneously in the hindguts of almost all termites, but the reasons for the apparent predominance of methanogenesis over homoacetogenesis in the hindgut of the humivorous species is not known. We found that in

Searching for Metabolic Pathways of Anaerobic Digestion: A Useful List of the Key Enzymes [PDF]

, 2019
The general scheme of anaerobic digestion is well known. It is a complex process promoted by the interaction of many groups of microorganisms and has four major steps: hydrolysis, acidogenesis, acetogenesis, and methanogenesis.
