Fig. 3. Binding of radioactivity following the treatment of 14C-2,4-DCP-polluted Soils 1 and 2 with free or immobilized laccase of Trametes villosa (3800 unit g-1) under different moisture conditions (30, 55, or 100% of maximum water-holding capacity, WHC). The SE for radioactivity (%) ranged between 0.1 and 4.0. A * indicates controls obtained by treating the 14C-2,4-DCP-polluted soils with Milli-Q water or montmorillonite without the enzyme.
