Biodegradation of Polycyclic Aromatic Hydrocarbons by Pseudomonas sp. PSS6 Isolated from Municipal Wastes Sediment

Polycyclic aromatic hydrocarbons are ubiquitous contaminants in environments impacted by fossil fuels directly or by the combustion of fossil fuels posing health hazards to human beings. This study investigated the ability of degrading PAHs (naphthalene, phenanthrene, anthracene and fluorene) by Pseudomonas sp. PSS6 isolated from municipal wastes collected from a waste dumping site. The strain PSS6 showed considerable growth over naphthalene, phenanthrene, anthracene, fluorene, as the sole carbon source with 1 mM concentration in Mineral Salt Medium (MSM) agar plates after 24 h. Pseudomonas sp. PSS6 showed greater degradation capability nearly around 100% against the PAHs tested.
