Pure and mixed cultures of bacteria isolated from fresh water and seawater have the capacity to metabolize,
anthracene, phenanthrene and as the only source of carbon anthracene are completely mineralized.

with the initial
oxygenated intermediate being a dihydriol (Mrozik et al., 2003).
While
Ochrobactrum anthropic
showed low degradation percentage of all concentrations (Table 2; Figure 18;
Figure 19; Figure 20; Figure 21). Sulaiman et al
.
(2016) found that, out of 35 isolates obtained from petroleum-
contaminated soil only five isolates have the ability to degrade phenanthrene and anthracene. Whereas Katsivela et
al. (2002) found that, 97% of 2; 2; 4; 4; 6; 8; 8- heptamethylnonane, 55% of toluene, 71% of acenaphthylene and
72% of acenaphthene were depleted after 9 days of growth. The ability of these bacteria to remove different PAHs
looks promising for use in bioremediation technologies.
