Mineralization of phenanthrene in the presence of biosurfactants produced by rhodococcus erythropolis

摘要

Polycyclic aromatic hydrocarbons (PAHs) are one of the significant contaminant groups in the environment threatening environmental sustainability and human health. Although most PAH compounds are biologically degradable, biodegradation rates for PAHs in the environment are frequently hindered by their low solubility and sorption to soil particles [1]. The potential use of surfactants to mobilize hydrocarbon contaminants from solid and NAPL phases has been extensively investigated, and several types of surfactants have been examined to treat soils contaminated with PAHs[2,3]
