Abstract

Polycyclic aromatic hydrocarbons (PAHs) released from various sources are reaching the environment. They are hazardous to vegetation and human health. The PAHs are carcinogenic and mutagenic. They cause various disorders among humans. Bioremediation which makes use of microbes to degrade such PAHs is a safe approach to remove PAHs from environment. The naphthalene is considered as model compound for PAHs biodegradation studies. In the present work three naphthalene degrading bacterial isolates viz., Bacillus, Micrococcus and Pseudomonas were grown in BSM broth supplemented with naphthalene and physical parameters were optimized. All the bacteria showed maximum naphthalene degrading ability at pH 7.0. Bacillus exhibited highest naphthalene degrading activity at 330 C whereas Micrococcus and Pseudomonas at 310 C. Dr. P.
