| 摘 要： | 从废水池污泥中分离到一株染料脱色曲霉ＷＺ－２,它对不同染料均有较好的脱色效果。在３３￣４０℃温度范围内ＷＺ－２对活性桃红ＫＤ－８Ｂ的脱色率为８４％￣９８％,最佳脱色温度为３３℃,ｐＨ值在４．０￣７．０范围内ＷＺ－２对直接耐晒翠蓝ＧＬ的脱色率为８３％￣９６％,最佳脱色ｐＨ为６．０,碳源、氮源及接种量对其脱色率均有影响,染料脱色物的紫外－可见光谱分析表明,可见光区５２０ｎｍ处的吸收峰完全消失,而紫外光

| Abstract: | A
dye-decolorizing fungus strain WZ-2 was isolated from sludge and it was very effective to
decolorize different dyes. The decolorizing rates were 84%～98% to Reactive Red KD-8B and 83%～96% to Direct Light Turquoise GL respectively, when
temperature was 33～40℃ and pH 4.0～7.0. The optimum temperature and pH of decolorization were
33℃ and 6.0,
respectively. Carbon sources, nitrogen sources, and inoculating amount could affect the
decolorizing rate. The dye degraded products were determined by UV-visible
spectrophotometer. The absorption peak in 520 nm was almost completely disappeared, while
the absorption in UV district was decreased. Fig 4, Tab 3, Ref 8 |
