Application of Response Surface Analysis to Evaluate the Effect of Concentrations of Ammonia and Propionic Acid on Acetate-Utilizing Methanogenesis

Energies, 2019
Ammonia and propionate are known inhibitors of anaerobic methanogenesis at higher concentrations, and are likely to coexist in digesters treating high-strength wastewater.

Selective inhibition of methanogenesis to enhance ethanol and n-butyrate production through acetate reduction in mixed culture fermentation [PDF]

, 2009
Acetate reduction is an alternative digestion process to convert organic waste into ethanol. Using acetate for fuel ethanol production offers the opportunity to use organic waste materials instead of sugar-containing feedstock.

The effect of Asparagopsis taxiformis, Ascophyllum nodosum, and Fucus vesiculosus on ruminal methanogenesis and metagenomic functional profiles in vitro

Microbiology Spectrum
The ruminant-microorganism symbiosis is unique by providing high-quality food from fibrous materials but also contributes to the production of one of the most potent greenhouse gases—methane.

Effects of coenzyme M and methyl-coenzyme M on the efficacy of inhibitors of methanogenesis in rumen cultures

Scientific Reports
Understanding the mechanisms of action of methanogenesis inhibitors can help interpret the variation in their efficacy for mitigating enteric methane (CH4) emissions from ruminants.

Fe0-dependent carbon dioxide reduction to methane via diverse electron transfer pathway in methanogenic community

Cell Reports Sustainability
Summary: In natural and engineered environments, iron biocorrosion is an energy reservoir for growth of methanogens. However, how archaea accept electrons from metallic iron remains enigmatic.

Methyl-coenzyme M reductase in archaeal methanogenesis: evolution, mechanism, and biotechnological perspectives

Frontiers in Catalysis
Methanogenesis is an anaerobic, energy-conserving metabolism that converts CO2, acetate, and methylated compounds to methane, constituting a key terminal step in the mineralization of organic matter in many oxygen-limited ecosystems.

A combination of microbial electrolysis cells and bioaugmentation can effectively treat synthetic wastewater containing polycyclic aromatic hydrocarbon

Water Science and Technology
The anaerobic biodegradation of polycyclic aromatic hydrocarbons (PAHs) is challenging due to its toxic effect on the microbes. Microbial electrolysis cells (MECs), with their excellent characteristics of anodic and cathodic biofilms, can be a viable way

Assessing stimulation and inhibition of anaerobic lagoons: Project 4C-105 [PDF]

, 2014
Covered anaerobic lagoons are critical to achieve low carbon pork, however, potential failure of pond systems is a key issue, especially with a number of potential inhibitors in piggery flush effluent.
