The maximum likelihood tree based on the LSU-SSU sequences from archaea and bacteria. All sequences were retrieved from whole genomes or from environmental genomic fragments that contain LSU-SSU operon. In the tree, 75G8 indicates the genomic fragment obtained in this study. The sequences of LSU-SSU operon were aligned using MAFFT with L-INS-i strategy. The maximum likelihood tree was computed by RAxML program using the general time-reversible (GTR) model of sequence evolution, by including a gamma-correction. The numbers at the nodes represent the non-parametric bootstrap values that were computed by RAxML.
