TL;DR: It was not only the species richness that was affected by temperature, but also the phylogenetic distribution of the microbial populations, suggesting a higher diversity compared to the community present at the thermophilic temperature.

TL;DR: The shift to SAO in the biogas digester resulted in a twofold decrease in the specific gas and methane yield, and the pathway for methane formation was determined by calculating the (14)CO(2)/(14)CH(4) ratio after incubating samples with ( 14)C-2-acetate.

TL;DR: The reaction pathway for the formation of methane from acetate was investigated in sludge from 13 different biogas reactors and it was shown that methane formation by syntrophic acetate oxidation was the dominating mechanism for acetotrophic methanogenesis inSludge containing high levels of salts, mainly ammonium, and volatile acids.

TL;DR: Strain BST was a spore-forming, gram-positive, rod-shaped organism which utilized formate, glucose, ethylene glycol, cysteine, betaine, and pyruvate and was a member of a new species of the genus Clostridium.

TL;DR: This review summarises current insight of syntrophic acetate oxidising microorganisms, their presence and the detection of novel species and relate these observations with operating conditions of the biogas processes in order to explore contributing factors for development of an ammonia-tolerant microbial community that efficiently degrades acetate through the syntrophic pathway.
