Fig. 2From: Diversity and community of methanogens in the large intestine of finishing pigsPhylogenetic analysis of methanogen partial mcrA sequences from finishing pig clone libraries inferred using MEGA (ver. 7). Evolutionary distances were calculated using the Neighbour-joining method. The tree was bootstrap resampled 1000 times.The 219 clones examined were assigned to 43 OTUs by DOTUR using a 97% species-level identityBack to article page
