In this study Lolium perenne plant species was selected for the purpose of investigation of its phytoremediation potential for soil anthracene removal (at 60, 120, 180 mg/kg concentrations) with the aid of growth-promoting bacteria (Bacillus aerophilus) and bacteria population after 45 and 90days. Results showed that the enhancement of anthracene disappearance is caused by an increase in the microbial community inoculation and microbial activity compared to that in un-inoculated soils. Enhanced dissipation in inoculated versus uninoculated soil with bacteria for Lolium perenne was 77.0-156.5ppm (for 180ppm anthracene). Our results show Lolium perenne is suitable candidates for the phytoremediation of soils contaminated with recalcitrant pollutants.
