摘　　要：以黄孢原毛平革菌为出发菌株,研究了转速、pH、酶对孔雀石绿生物脱色效果的影响,以及不同质量浓度孔雀石绿的生物脱色率.结果表明,转速、pH值及不同质量浓度孔雀石绿对脱色率的影响均达显著水平(P<0.05),当转速为150 r.min-1,pH4.5的条件下脱色效果最佳.10 mg.L-1的孔雀石绿在24 h内脱色率为98.32%,30 mg.L-1的孔雀石绿在72 h内脱色率也超过90%.酶在脱色过程中起着主要作用.The effects of rotational speed, pH and enzymes on biodecolorization of malachite green by Phanerochaete chrysosporium are studied, as well as biodecolorization of malachite green of different concentration. The result shows that rotational speed, pH and concentration of malachite green signifi- cantly affect the decolorization rate （ P 〈 0.05 ）. The optimum decolorizing rotational speed and pH are 150 r · min^-1 and 4.5 ,respectively. The decolorization rate of 10 mg · L^-1 malachite green within 24 h is up to 98.32 % , and the decolorization rate of 30 mg·L^-1 malachite green is beyond 90 % within 72 h. The enzyme plays a major role in malachite green decolorization.
