Abstract

Bioemulsifier production, the biodegradation abilities and initial dioxygenase gene of a Bacillus strain isolated from marine Indonesia was investigated. The 16S rDNA sequence revealed that the strain was Bacillus subtilis. The B. subtilis possessed nahAc and nidA genes encoding the initial dioxygenase required for pyrene degradation. The B. subtilis also could completely degrade a polycyclic aromatic hydrocarbon (PAH) of pyrene in 30 days. We suggest that the bioemulsifier that was also produced by the B. subtilis, may assist the bacteria to attach the pyrene for degradation.
