Decolorization and Mechanisms of Acid Blue 45 Biodegradation by Fusarium sp.

摘要：

The anthraquinone dye C.I. acid blue 45 (AB45), potential toxicity and recalcitrant dye, is a major colored component from the effluent of textile and printing plants. Fusarium sp. HJ01 can grow using AB45 as only carbon resource and has strong ability of AB45 degradation. The effects of pH, temperature and biomass addition on biodegradative capacity of Fusarium sp. HJ01 were examined. The HJ01 strain produced only one lacc ase protein, which molecular mass is approximately 66 kD, played very i mportant role in the degradation of AB45. The activity of laccase was up to from 431 U/mg to 812 U/mg at the condition of lower nitrogen source, its feasible temperature 65 ℃and pH 4.0. The HJ01 incubated for 96 h at 25 ℃and 50 r/min on the shaker were added to AB45 solution, and cultured continuously for 96 h at 35 ℃and pH 4.0 on the same shaker, the decolorization rate of AB45 was over 97%.
