Trace element requirements for stable food waste digestion at elevated ammonia concentrations [PDF]

, 2012
The work investigated why anaerobic digesters treating food waste and operating at high ammonia concentrations suffer from propionic acid accumulation which may result in process failure.

Phytoplankton lipid content influences freshwater lake methanogenesis [PDF]

, 1900
1. Rates of methanogenesis in freshwater sediments have been shown to increase with inputs of phytoplankton biomass. Although many studies have shown the importance of resource quality for decomposition, little is known of the importance of substrate ...

Effects of Copper Sulfate and Encapsulated Copper Addition on In Vitro Rumen Fermentation and Methane Production

Agriculture, 2022
Copper is a microelement crucial for the proper functioning of animals’ metabolic processes. The function of copper in rumen fermentation processes and methanogenesis is not well analyzed.

Cobalt toxicity in anaerobic granular sludge: influence of chemical speciation [PDF]

, 2008
The influence of cobalt speciation on the toxicity of cobalt to methylotrophic methanogenesis in anaerobic granular sludge was investigated. The cobalt speciation was studied with three different media that contained varying concentrations of complexing ...

Organic matter supply and bacterial community composition predict methanogenesis rates in temperate lake sediments

Limnology and Oceanography Letters, 2019
The objective of our study was to identify environmental conditions that structure lake sediment microbial communities and determine whether community composition explained inter‐lake variation in potential methanogenesis rates.

Inhibiting Methanogenesis Stimulated de novo Synthesis of Microbial Amino Acids in Mixed Rumen Batch Cultures Growing on Starch but not on Cellulose

Microorganisms, 2020
Ameliorating methane (CH4) emissions from ruminants would have environmental benefits, but it is necessary to redirect metabolic hydrogen ([H]) toward useful sinks to also benefit animal productivity.

A multienzyme complex channels substrates and electrons through acetyl-CoA and methane biosynthesis pathways in Methanosarcina.

PLoS ONE, 2014
Multienzyme complexes catalyze important metabolic reactions in many organisms, but little is known about the complexes involved in biological methane production (methanogenesis). A crosslinking-mass spectrometry (XL-MS) strategy was employed to identify

Aquaculture drastically increases methane production by favoring acetoclastic rather than hydrogenotrophic methanogenesis in shrimp pond sediments [PDF]

, 2023
International audienceEmissions of methane (CH4), a major greenhouse gas, should be cut by at least 30% by 2030 according to the last Conference of the Parties, CoP26.
