Comparative Genome Characterization of a Petroleum-Degrading Bacillus subtilis Strain DM2

Figure 4

Neighbor-joining phylogenetic tree based on the protein sequences of 24 housekeeping genes of the Bacillaceae family members. The members of B. subtilis (orange-colored), outgroups of B. subtilis (blue-colored), the members of B. velezensis and B. amyloliquefaciens (green-colored), and the isolates from the crude-oil environment (red-colored) are included.
