Abstract:
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
