The biological decolorization methodology and the mechanism involved in the degradation of Acid Red 66 was chosen as a model of azo dye using the white rot fungi Trametes versicolor was studied. Biodecolorization of Acid Red 66 using white rot fungi T. versicolor was demonstrated by the decolorization of the culture medium, the extent of which was determined by monitoring the decrease in absorbance at 506 nm. The biodecolorization kinetics of Acid Red 66 (100 ppm) was found to be first order and the degradation rate coefficient is 1.312 x 10(-2)min(-1) (R=0.96683, n=8) at 30 degrees C. The effects of independent variables such as carbon sources, nitrogen sources pH, and temperature on the biodecolorization of Acid Red 66 was also investigated.
以云芝白腐真菌为模型，研究了偶氮染料酸性红66降解过程中的生物脱色方法及相关机制。通过监测培养基在506nm处吸光度的降低来确定云芝白腐真菌对偶氮染料酸性红66的生物脱色效果。发现酸性红66（100ppm）的生物脱色动力学符合一级反应，在30℃时降解速率系数为1.312×10⁻²min⁻¹（R = 0.96683，n = 8）。还研究了碳源、氮源、pH值和温度等自变量对酸性红66生物脱色的影响。
