Fatty acids and alcohols are key intermediates in the methanogenic degradation of organic matter, e.g., in anaerobic sewage sludge digestors or freshwater lake sediments. They are produced by classical fermenting bacteria for disposal of electrons derived in simultaneous substrate oxidations. Methanogenic bacteria can degrade primarily only one-carbon compounds. Therefore, acetate, propionate, ethanol, and their higher homologs have to be fermented further to one-carbon compounds. These… 

Assessment of hydrogen metabolism in commercial anaerobic digesters

Addition of H2 significantly increased the rate of methane formation, which suggested that hydrogenotrophic methanogenesis is not a rate-limiting step during biogas formation, and hydrogenase activity in cell-free extracts from digester sludge correlated with methane productivity in a positive fashion.

Formate and Hydrogen as Electron Shuttles in Terminal Fermentations in an Oligotrophic Freshwater Lake Sediment

The energetic consequences of formate versus hydrogen transfer in secondary and methanogenic fermentations indicate that both carrier systems are probably used simultaneously to optimize the energy yields for the partners involved.

Syntrophy in Methanogenic Degradation

This chapter deals with microbial communities of bacteria and archaea that closely cooperate in methanogenic degradation and perform metabolic functions in this community that neither one of them

Energy conservation mechanisms and electron transfer in syntrophic propionate-oxidizing microbial consortia

A functional analysis of protein domains was performed on a selected group of bacteria with the ability to grow on short chain fatty acids alone, or in syntrophy with methanogens, and indicated that confurcating hydrogenases and formate dehydrogenases are important energy converting enzymes in propionate degradation by S. fumaroxidans.

Biogas process parameters—energetics and kinetics of secondary fermentations in methanogenic biomass degradation

Pool sizes of short-chain fatty acids, hydrogen, and carbon monoxide were assayed in digesting sludge from four different methanogenic reactors degrading either sewage sludge or agricultural products and wastes, indicating that acetate, propionate, and butyrate degradation all supplied sufficient energy to sustain the microbial communities involved in the respective processes.

Kinetics of syntrophic cultures: a theoretical treatise on butyrate fermentation.

By using nonfixed stoichiometries for the membrane associated processes, the required flexibility of anaerobic bacteria to adapt to varying environmental conditions can be described.

Syntrophic butyrate and propionate oxidation processes: from genomes to reaction mechanisms.

In anoxic environments such as swamps, rice fields and sludge digestors, syntrophic microbial communities are important for decomposition of organic matter to CO2 and CH4 . The most difficult step is

Syntrophic propionate-oxidizing bacteria in methanogenic systems

Differences in gene repertoire and organization for the methylmalonyl-CoA pathway, hydrogenases and formate dehydrogenases, and emerging facets of (formate/hydrogen/direct) electron transfer mechanisms are discussed.



Characterization of metabolic performance of methanogenic granules treating brewery wastewater: role of sulfate-reducing bacteria

The data show that in this granular microbial consortium, methanogens and sulfate-reducing bacteria did not compete for common substrates.

Influence of pH on Terminal Carbon Metabolism in Anoxic Sediments from a Mildly Acidic Lake

Analysis of both carbon transformation parameters with C-labeled tracers and bacterial trophic group enumerations indicated that methanogenesis from acetate and both heterolactic- and acetic acid-producing fermentations were important to the anaerobic digestion process.

Thermodynamics of H2-consuming and H2-producing metabolic reactions in diverse methanogenic environments under in situ conditions

In situ concentrations of hydrogen and other metabolites involved in H2-consuming and H2-producing reactions were measured in anoxic methanogenic lake sediments, sewage sludge and fetid liquid of

Thermodynamics of hydrogen metabolism in methanogenic cocultures degrading ethanol or lactate

Calculation of Gibbs free energies for the prevailing culture conditions showed that H2 partial pressures were kept in a range at which both, H1-producing and H2-consuming reactions, were thermodynamically permissive in pure as well as in syntrophic mixed cultures.

Gas Metabolism Evidence in Support of the Juxtaposition of Hydrogen-Producing and Methanogenic Bacteria in Sewage Sludge and Lake Sediments

The results are in general agreement with the results reported previously and are used to support the conclusion that most of the H(2)-dependent methanogenesis in these ecosystems occurs as a consequence of direct interspecies H( 2) transfer between juxtapositioned microbial associations within flocs or consortia.

Energetics of methanogenic benzoate degradation by Syntrophus gentianae in syntrophic coculture.

It is concluded that the minimum energy required for growth and energy conservation of the benzoate-fermenting bacterium S. gentianae is approximately -45 kJ (mol Benzoate)-1, equivalent to two-thirds of an ATP unit.

Growth of Desulfovibrio in Lactate or Ethanol Media Low in Sulfate in Association with H2-Utilizing Methanogenic Bacteria

The results with known mixtures of bacteria suggest that hydrogenase-forming, sulfate-reducing bacteria could be active in some methanogenic ecosystems that are low in sulfate, and it is suggested that lack of availability of H(2) for growth of methanogens is a major factor in suppression of meetinghanogenesis by sulfate in natural ecosystems.

Control of Interspecies Electron Flow during Anaerobic Digestion: Significance of Formate Transfer versus Hydrogen Transfer during Syntrophic Methanogenesis in Flocs

A model is presented which describes the dynamics of a bicarbonate-formate electron shuttle mechanism for control of carbon and electron flow during syntrophic methanogenesis and provides a novel mechanism for energy conservation by syntrophic acetogens.

Microbiology and Biochemistry of Strict Anaerobes Involved in Interspecies Hydrogen Transfer

This FEMS Symposium is devoted to the interspecies hydrogen transfer phenomenon involved in the mineralization of organic matter in anaerobiosis, carried out in Nature by consortia of anaerobic micro-organisms living syntrophically.

Bioenergetic Conditions of Butyrate Metabolism by a Syntrophic, Anaerobic Bacterium in Coculture with Hydrogen-Oxidizing Methanogenic and Sulfidogenic Bacteria

The bioenergetic homeostasis the authors observed in phase b was a result of the kinetics of the coculture members and the feedback inhibition by hydrogen which prevents butyrate degradation rates from reaching their theoretical V(max).
