Isolation and Characterization of Diesel-Degrading Bacteria from Hydrocarbon-Contaminated Sites, Flower Farms, and Soda Lakes

Figure 4

Phylogenetic tree based on partial bacterial sequences of the 16S rRNA region for the two Pseudomonas isolates and one Bacillus subtilis (bold and coded with the initials “AAU”) and accession numbers of the 16S rRNA are followed by species names. Numbers at nodes indicated bootstrap values for each node out of 1,000 bootstrap resembling. The phylogenetic tree was constructed in MEGA X using the maximum likelihood method [48] and Kimura-2 parameter model [32]. The Escherichia coli partial sequence was used as an out-group.
