Bacteria Methanogens/Methanogenic

Environmental effects, including effect on methanogenic and nitrifying bacteria, persistence in the environment, and projections of possible HabiUty to relevant ecosystems. 

Hackstein et al ° have suggested that there may be a phylogenetic basis for the occurrence of significant methane formation in the gut of animals. It was argued that this refiected the presence of a methanogen receptor in the gut of animals which support large populations of these bacteria, since the production of...

These reductases play a key role both in methanogenesis and in the degradation of phenols that carry several nitro groups, which is discussed further in Chapter 9, Part 5. Although these reductases are typically found in methanogens, they have been encountered in a number of other bacteria and archaea ...
