Phylogenetic trees of predominant genera in different samples.

<p>The phylogenetic tree was inferred using the neighbor-joining method with MEGA6.0 and the bootstrap value was 1000 replications. Only the branch with bootstrap value >500 are shown in the tree. (a) for CK-144-F, (b) for CK-144-M, (c) for CPV-144-F, and (d) for CPV-144-M; the numbers in parentheses represented the percentage of a predominant genus. Serial numbers from 1–12 represented the <i>Delftia</i>, <i>Pelomonas</i>, <i>Tepidimona</i>, <i>Ralstonia</i>, <i>Aspromonas</i>, <i>Pseudomonas</i>, <i>Enterococcus</i>, <i>Methylobacterium</i>, <i>Staphylococcus</i>, <i>Tepidimonas</i>, <i>Corynebacterium</i> and <i>Brevibacterium</i> genera, respectively. Samples CK (CPV)-144-F (M) were mentioned in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0146313#pone.0146313.t001" target="_blank">Table 1</a>.
