Neighbour joining phylogenetic tree of Desulfovibrio desulfuricans isolated in the present study along with reference sequences recovered from the NCBI GenBank database. The current tree was derived from the analysis of 16S rRNA sequences. Bootstrap support values at each node are indicated by numbers (percentage of 1,000 replicates). Values above 70% are displayed only. The bar represents 0.02 substitutions per nucleotide position. The bacterial isolate from the current study is denoted by green. Staphylococcus aureus is used as an outgroup.
