Abstract
ABSTRACT
Laboratory treatability study results demonstrated that bioaugmentation of the hazardous soil composting system with the white rot fungus Phanerochaete chrysosporium resulted in complete Alachlor transformation within 56 days of treatment. Alachlor transformation rates were enhanced by more than an order of magnitude as a result of fungal inoculation as compared to soil only and organic amendment systems. First order transformation reaction rates were estimated to be 0.0098, 0.012 and 0.185 day−1 for the soil only, organic amendment and fungal inoculated systems, respectively. These transformation rates corresponded to average contaminant half lives of 70.7, 57.8,. and 3.7 days for the soil only, soil plus organic amendment, and fungal amended system, respectively. A maximum transformation rate of 18.25 mg Alachlor/kg soil-day was observed for the fungal inoculated system.
