Naphthalene is a simplest Polycyclic Aromatic Hydrocarbon (PAH). PAHs are major contaminants of environment, associated
with common anthropogenic activities such as oil refineries and incomplete combustion of fossil fuels. PAHs are toxic,
mutagenic and carcinogenic. Isolation of naphthalene degrading bacteria is recommended by a complex ONR 7a medium. Present
work includes a modified medium with Naphthalene as a sole source of carbon. Four isolates were isolated from marine sample
collected from Mumbai as well as petroleum soil sample from Trimbak road Satpur, Nashik. Further characterization using
morphological and biochemical tests showed resemblance with Gram positive bacteria as well as Gram negative bacteria and they
may belong to genus such as Micrococcus spp , Bacillus spp, Staphylococcus spp, Pseudomonas spp. These strains were further grown
in modified broth for 45 days as well as on ONR 7a agar medium. In turbidometric assay Bacillus spp showed significant growth
at 1 mg/ml of naphthalene concentration. Catechol which is generated through biodegradation of naphthalene was detected by
Winkelmann modified Arnow?s method. All the four isolates efficiently degraded naphthalene which was confirmed by Arnow?s
test. These naphthalene degraders could be further checked and explored for their efficiency in bioremediation of polluted marine
environment and in oil contaminated fields.
