Figure 3: Phylogenetic analysis based on partial 16S rRNA sequences (~1000 pb) obtained from the bacteria belonging to the Phylum Actinobacteria isolated from oil and formation water samples and related species. Bootstrap values (1,000 replicate runs, shown as %) greater than 70% are listed. GenBank accession numbers are listed after species names. Achromobacter xylosoxidans was used as outgroup.
