Abstract

The rates of solubilization and biodegradation of polycyclic aromatic hydrocarbons (PAH) in the presence of non-ionic surfactants using mixed bacterial consortia are studied. The concentrations of non-ionic surfactants below 1% are capable of large increases of 2-3 orders of magnitude in the solubility of model PAH compounds viz. fluorene, phenanthrene and pyrene. However, the microbial consortia had no inhibition effects for surfactant concentrations of up to 1%. In the absence of Makon 10, no substantial reduction in the PAH concentration was observed, whereas approximately 85% reduction was observed in the presence of the surfactant.
