dioxygenase in the ASU-06 strain of
S. koreensis
the existence of monooxygenase genes (alkB and alkB1)
dioxygenase (naháč) and Catechol dioxygenase (
C12O
and
C23O
) genes was confirmed. Therefore, one possible
reason may be that these genes are strong evidence between different conserved Gram-negative bacteria (Hesham
et al., 2014).

3 Conclusion
In this study, 4 oil degrading bacterial strains were isolated from brackish water. The bacteria were identified as
Brevundimonas diminuta/ vesicularis
,
Vibrio vulnificus
,
Sphingomonas paucimobilis
and
Ochrobactrum anthropic
based on morphological properties and by Vitek II system. We found a variation in their capabilities to degrade
PAH and most effective in higher concentrations. Perhaps, this is related to the types of bacteria and the
mechanisms which to degrade crude oil.
