Biodegradation of polyaromatic hydrocarbons (PAHs) are catalyzedby multicomponent enzymes from microbe. The initial dioxygenase was used as a key enzyme for attacking the aromatic ring structure of PAHs, furthermore its initial dioxygenase gene was used to select PAHs degrading bacteria. Marine bacteria M128 strain could grow on medium contained PAHs. Detection of its cellular initial deoxygenase gene was done by nahAcgene amplification. The nahAcgene commonly used as biomarkers of PAH degradation, and as a result, nahAcgene sequence analysis of marine bacteria M128strain was similar to naphthalene dioxygenase of Pseudomonas genera with 99% homology.
