Biodegradation of 2,4-Dichlorophenol from Aqueous Solution by Immobilized Phanerochaete chrysosporium

The biodegrading effect of 2,4-Dichlorophenol from aqueous solution by immobilized Phanerochaete chrysosporium was studied and the feasibility of using immobilized Phanerochaete chrysosporium to treat the chlorophenols-contamination water was investigated. The results showed clearly that the stability of enzymes production and enzymes activity were remarkably improved after immobilization of the free Phanerochaete chrysosporium. The biodegrade efficiency can be influenced by immobilized spore dose, optimum pH, rotating speed, initial 2,4-DCP concentration and surfactant concentration. The biodegrading efficiency was best when pH 4.5, rotate speed 180 r / min, surfactant Tween 80 1% w / v, the initial 2,4-DCP concentration was 40 mg / L and adding 10 mL immobilized spores.
