AB  - Phanerochaete chrysosporium has been recognised as an effective bioremediation 
      agent due to its unique degradation to xenobiotic and biosorption ability to 
      heavy metals. However, few studies have focused on the simultaneous removal of 
      heavy metals and organic pollutants. The aim of this work was to study the 
      feasibility of simultaneous cadmium removal and 2,4-dichlorophenol (2,4-DCP) 
      degradation in P. chrysosporium liquid cultures. The removal efficiencies were pH 
      dependent and the maximum removal efficiencies were observed at pH 6.5 under an 
      initial cadmium concentration of 5 mg/L and an initial 2,4-DCP concentration of 
      20 mg/L. The removal efficiencies for cadmium and 2,4-DCP reached 63.62% and 
      83.90%, respectively, under the optimum conditions. The high production levels of 
      lignin peroxidase (7.35 U/mL) and manganese peroxidase (8.30 U/mL) resulted in an 
      increase in 2,4-DCP degradation. The protein content decreased with increasing 
      cadmium concentration. The surface characteristics and functional groups of the 
      biomass were studied by scanning electron microscopy and a Fourier-transformed 
      infrared spectrometer. The results showed that the use of P. chrysosporium is 
      promising for the simultaneous removal of cadmium and 2,4-DCP from liquid media.
