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.

TL;DR: Based on the phylogenetic position and the physiological characteristics of strain Sp3(T), this new syntrophic, acetate-oxidizing bacterium is proposed as the new genus and species Syntrophaceticus schinkii, with Sp3 (T) (=JCM 16669(T)) as the type strain.

TL;DR: The findings further demonstrate the strong influence of ammonia on the methane-producing consortia and on the representative methanization pathway in mesophilic biogas reactors.

TL;DR: The genetic and phenotypic properties of strains Re1(T), Re2, T1 and T2 suggest classification as representatives of a novel species of the genus Tepidanaerobacter; the name Tepicutes-Clostridia acetatoxydans sp.

TL;DR: Evidence of functional importance of the bacterial families identified in high-ammonia systems is provided and existing knowledge of bacterial and acetogenic assemblages at low and high ammonia levels is extended.
