摘　　要：碳源、氮源、Mn2 +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(NH4 Cl) 0 .13g/L ,ρ(Mn2 +) 2 0mg/L .随葡萄糖和NH4 Cl添加量的增加 ,菌体生物量增加 .但高浓度的NH4 Cl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pH值为 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 .图 9表 1参Carbon, nitrogen sources, Mn 2+ 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(NH 4Cl) 0.13 g/L, ρ(Mn 2+ ) 20 mg/L. As ρ(glucose) and ρ(NH 4Cl) increased, there was a corresponding increase in the biomass. The high concentration of NH 4Cl 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
