	1	Degradation of direct azo dye by Cucurbita pepo free and immobilized peroxidase显示文摘Enzymatic decolourization of the azo dye,Direct Yellow(DY106) by Cucurbita pepo(courgette) peroxidase(CP) is a complex process,which is greatly affected by pH,temperature,enzyme activity and the concentrations of H2O2 and dye.Courgette peroxidase was extracted and its performance was evaluated by using the free-CP(FCP) and immobilized-CP(ICP) forms in the decolourization of DY106.Immobilization of peroxidase in calcium alginate beads was performed according to a strategy aiming to minimize enzyme leakage and keep its activity at a maximum value by optimizing sodium alginate content,enzyme loading and calcium chloride concentration.The initial conditions at which the highest DY106 decolourization yield was obtained were found at pH 2,temperature 20℃,H2O2 dose 1 mmol/L(FCP) and 100 mmol/L(ICP).The highest decolourization rates were obtained for dye concentrations 50 mg/L(FCP) and 80 mg/L(ICP).Under optimal conditions,the FCP was able to decolorize more than 87% of the dye within 2 min.While with ICP,the decolourization yield was 75% within 15 min.The decolourization and removal of DY106 was proved by UV-Vis analysis.Fourier transform infrared(FT-IR) spectroscopy analysis was also performed on DY106 and enzymatic treatment precipitated byproduct.
