Pirts maintenance coefficient for methanogen
Webb5 jan. 2012 · Enteric methane emitted by livestock species is produced by symbiotic methanogens which use as substrates the CO 2 and H 2 that result from digestion of plant fibers in the gastrointestinal tract of their host. Because it is not assimilated, methane is released into the environment, mostly through eructation [].Since this process results in … WebbAbstract. To date, a great number of oligonucleotide probes/primers targeting phylogenetic markers of methanogenic archaea (methanogens), such as 16S rRNA and the gene for the α-subunit of methyl-coenzyme M reductase ( mcrA ), have been developed and used for the identification and quantification of individuals and groups of methanogens in ...
