| 摘 要： | 碳源、氮源、Mn^2 浓度及pH值对F7菌漂白废水脱色有较大的影响，最佳培养基组成为：ρ（葡萄糖）10g/L，ρ（NH4Cl）0．13g/L，ρ（Mn^2 )20mg/L，随葡萄糖和NH4Cl添国量的增加，菌体生物量增加，但高浓度的NH4Cl对F7菌脱色有抑制作用，F7菌适宜生长pH值为4－5，适宜脱色pHwfhgo 3-6,最适脱色pH值为5．0另外，经脱色处理的漂白废水的毒性明显下降。

| Abstract: | Carbon, nitrogen sources, Mn2+ and pH are important for bleaching effluent decolorization by fungus F7. The results showed that the optimum culture conditions were ρ(glucose) 10 g/L，ρ(NH4Cl) 0.13 g/L, ρ（Mn2+） 20 mg/L. As ρ(glucose) and ρ(NH4Cl) increased, there was a corresponding increase in the biomass. The high concentration of NH4Cl would repress the decolorization of effluent by fungus F7. pH 4～5 was suitable for fungal growth and pH 3～6 for fungal decolorization, while the optimum culture conditions for decolorization was at pH 5. The toxicity could be eliminated after effluent treated with white-rot fungus. Fig 9, Tab 1, Ref 13 |
