In this paper, degradation of sulfamethoxazole(SMX) by the white-rot fungus Phanerochaete chrysosporium was assessed. P. chrysosporium had a stronger tolerance for SMX in the concentration range of 10-30mg/L. The degradation percentage of SMX in liquid medium was 53% after 24h and reached 74% after 10 days when SMX was added at 10mg/L. Crude laccase produced by P. chrysosporium was used to degrade SMX in vitro. The results showed that the removal of SMX obviously increased with laccase activity and reaction time increasing.
