The potential of Penicillium chrysogenum to decolorize azo dyes and a real industrial textile wastewater was studied. P. chrysogenum was able to decolorize and degrade three azo dyes (200 mg L(-1)), either independently or in a mixture of them, using glucose as a carbon source. A kinetic model for degradation was developed and it allowed predicting the degradation kinetics of the mixture of the three azo dyes. In addition, P. chrysogenum was able to decolorize real industrial wastewater. The kinetic model proposed was also able to predict the decolorization of the real wastewater. The calibration of the proposed model makes it a useful tool for future wastewater facilities' design and for practical applications.
研究了产黄青霉对偶氮染料和实际工业纺织废水进行脱色的潜力。产黄青霉能够以葡萄糖作为碳源，单独或混合降解三种偶氮染料（200 mg L(-1)）。建立了降解动力学模型，该模型能够预测三种偶氮染料混合物的降解动力学。此外，产黄青霉能够对实际工业废水进行脱色。所提出的动力学模型也能够预测实际废水的脱色情况。该模型的校准使其成为未来废水处理设施设计和实际应用的有用工具。
