Neighbour-joining tree illustrating the phylogenetic identities of bacterial communities in the pressure bioreactor. The bacterial 16S rRNA gene fragments were obtained from clone samples. Clone counts of each OTU are given in brackets; numbers in series indicate the counts derived from samples F, L and U, respectively. Numbers at nodes are bootstrap values derived from 100 analyses. The scale bar represents an amount of nucleotide sequence change of 0.03
