Fig 3. Bayesian consensus tree based on RJMCMC approach of the 16S rRNA gene sequences of the environmental Antarctic strains isolated and closely related species obtained from GenBank.

The codes indicate the environmental Antarctic strains isolated (see S1 Table). The GenBank accession number follows specific names of the closely related species found in the database. The red numbers at tree nodes are posterior probabilities values (only >0.9 posterior probability) obtained from 2176 samples of phylogenetic trees. Scale bar represents 5% estimated substitutions.
