Biodegradation of Polycyclic Aromatic Hydrocarbon Compound by Bacterial Cultures

Abstract

In the present study biodegradation of Polycyclic Aromatic Hydrocarbon (PAH) compound Naphthalene by four bacterial cultures Bacillus subtilis PD6, Bacillussp. PD9, Enterobactersp. PD11 and Bacillussp. PD14 has been targeted. Biodegradation of Naphthalene by these four selected bacterial cultures was analysed by HPLC (High Performance Liquid Chromatography) technique. HPLC analysis revealed biodegradation of naphthalene by all the four bacterial cultures within a span of six days. Highest biodegradation 78.1% has been shown by Bacillus subtilis PD6 while other bacterial cultures Bacillus sp. PD9 has shown 77.90%, Enterobacter sp. PD11 showed 74.4% and Bacillus sp. PD14 exhibited 73.5% biodegradation of naphthalene.
