Influence of environmental conditions on methanogenic compositions in anerobic biogas reactors
Article Abstract:
The influence of environmental parameters on the diversity of methanogenic communities in 15 full-scale biogas plants operating under different conditions with either manure or sludge as feedstock is studied. The methanogenic diversity was greater in reactors operating under mesophilic temperatures and the impact of the original inoculum used for the reactor start-up was examined by assessment of the present population in the reactor.

Acetate oxidation is the dominant methanogenic pathway from acetate in the absence of Methanosaetaceae
Article Abstract:
A study surveyed 13 anaerobic reactors and sediment from a temperature anaerobic lake for their dominant methanogenic population by using fluorescent in situ hybridization and for the degree of acetate oxidation relative to aceticlastic conversion. Aceticlastic conversion was observed only in the presence of Methanosaetaceae and during the absence of Methanosaetaceae, acetate oxidation was the dominant methanogenic pathway.

Methanosarcina spp. drive vinyl chloride dechlorination via interspecies hydrogen transfer
Article Abstract:
Two highly enriched cultures containing Dehalococcoides spp. are used to study the effect of aceticlastic methanogens on reductive vinyl chloride (VC) dechlorination. In terms of aceticlastic methanogens, one culture is dominated by Methanosaeta, while the other culture is denominated by methanosarcina, as determined by fluorescene in situ hybridization.
