Comparison of three bioremediation agents for mineralization and transformation of pentachlorophenol in soil

Bacteria and fungi have been proposed as bioremediation agents for soil polluted with pentachlorophenol (PCP), and have been studied separately under various conditions. Because rate and extent of PCP degradation, as well as formation of transformation products, can differ among PCP-metabolizing mic...

Description
Summary:Bacteria and fungi have been proposed as bioremediation agents for soil polluted with pentachlorophenol (PCP), and have been studied separately under various conditions. Because rate and extent of PCP degradation, as well as formation of transformation products, can differ among PCP-metabolizing microbes and can be influenced by soil conditions, the study described here compares the activity under similar soil conditions of two bacteria (strains of Pseudomonas and Flavobacterium) and a fungus (Phanerochaete sordida) with respect to laboratory-scale bioremediation of a sandy, low-organic matter soil that was amended with known quantities of radiolabelled PCP.
