Table 3 The copy numbers of Methanobrevibacter, M. smithii and M. boviskoreani in samples from pigs of the four groups

From: Dietary pea fiber increases diversity of colonic methanogens of pigs with a shift from Methanobrevibacter to Methanomassiliicoccus-like genus and change in numbers of three hydrogenotrophs
