MATERIALS AND METHODS
Microorganism and wastewater
White-rot fungus Coriolus versicolor RC3 isolated from Chiang Mai, was used in this experiment. One-hundred-and-fifty ppm of commercial dye and textile wastewater from Batik factory in Lamphun were used as synthetic and real wastewater, respectively.
Preparation of immobilized C. versicolor RC3, immobilized support and medium
Polyurethane foam (PUF) was cut into 1.5 cm3 pieces and pretreated by boiling for 10 minutes, washing 2 times with distilled water. After drying overnight at room temperature, pretreated PUF was used as an immobilized support. Potato dextrose agar (PDA) was used to maintain the fungal strain. Immobilized C. versicolor RC3 was prepared by transferring 1 g of 1.5 cm3 of PUF into 50 ml potato dextrose broth (PDB) in 250 ml Erlenmeyer flask and inoculated with one agar plug (diameter, 1 cm) of the fungal strain. The culture was incubated in a rotating shaker at 120 rpm and 37°C for 4 days. The colonized fungal cells on PUF were used as the immobilized cells and inoculum.
