Abstract :
The concentration-time curve could be obtained through the biodegradation experiment of 1-chloronaphthalene and 2-chloronaphthalene at different concentration by Pseudomonas sp HY. And the influence of growth substance on the degradation was also investigated. The metabolite was detected by GC-MS(gas chromatography-mass spectrometer). The results show that after hydroxylation reactions, the chlorinated naphthol or chlorinated dihydroxyl naphthalene was produced. Then the ring of metabolite cracked and chlorosalicylic acid was generated through oxidation of the metabolite.
