Biodegradation ability and dioxgenase genes of PAH-degrading Sphingomonas and Mycobacterium strains isolated from mangrove sediments
The biodegradation ability and initial dioxygenase genes of 21 PAH-degrading bacteria isolated from mangrove sediments were investigated. Most of the isolates belonged to the genera of Sphingomonas and Mycobacterium, and the other included Rhodococcus, Paracoccus and Pseudomonas. All the isolated My...

| description | The biodegradation ability and initial dioxygenase genes of 21 PAH-degrading bacteria isolated from mangrove sediments were investigated. Most of the isolates belonged to the genera of
Sphingomonas and
Mycobacterium, and the other included
Rhodococcus,
Paracoccus and
Pseudomonas. All the isolated
Mycobacterium strains could completely degrade a mixture of polycyclic aromatic hydrocarbons (PAHs) comprising phenanthrene (Phe), fluoranthene (Fla) and pyrene (Pyr) in 14 days. On the other hand, the sphingomonads differed in the extent to which mixed PAHs were degraded from 3% to 79%. The co-culture of
Sphingomonas and
Mycobacterium strains enhanced the degradation and all three PAHs were completely removed in 7 days. Among the three PAHs, only Pyr was completely degraded by three
Mycobacterium strains (SBSW, YOWG and SKEY), whereas Fla, and then Phe were degraded by these three and other isolates. The isolated
Mycobacterium strains possessed the
nidA gene encoding the initial dioxygenase required for Pyr degradation, while
nahAc and
phnAc were not detected in the sphingomonads. |
