A number of different strategies have been adopted where attempts have been made to exploit fungi in bioremediation. Early findings demonstrated that attempts to establish wood rotting species in soil without amendments or soil sterilization failed. Like the early failures in establishing biological control agents in soil (Faull 1986), the indigenous micro flora out-competed the inoculants unless there were large additions of substrates such as wood chips and other ligno-cellulosic materials to the soil (Bennett et al. 2002; Cerniglia and Sutherland 2002; Radtke et al. 1994). Currently, a number of approaches are being tried, including soil piles and windrows (where "composting" may occur), soil farming, soil slurry reactors, and fixed film reactors (Rogers and Bunce 2001).
