Intensive research studies have revealed that fungal decolorization of dye wastewater is a promising replacement for the current process of dye wastewater decolorization. The authors isolated an Aspergillus sp. from the effluent of a textile industry area in Korea and assessed the effects of a variety of operational parameters on the decolorization of methyl red (MR) by this strain of Aspergillus sp. This Aspergillus sp. was then immobilized by entrapment in several polymeric matrices and the effects of operational conditions on MR decolorization were investigated again. The optimal decolorization activity of this Aspergillus sp. was observed in 1% glucose at a temperature of 37 °C and pH of 6.0. Furthermore, stable decolorization efficiency was observed when fungal biomass was immobilized into alginate gel during repeated batch experiment. These results suggest that the Aspergillus sp. isolated in Korea could be used to treat industrial wastewaters containing MR dye.
深入的研究表明，真菌对染料废水的脱色是目前染料废水脱色工艺的一种有前景的替代方法。作者从韩国一个纺织工业区的废水中分离出一株曲霉属真菌，并评估了各种操作参数对该曲霉属菌株对甲基红（MR）脱色的影响。然后，将该曲霉属真菌通过包埋固定在几种聚合物基质中，并再次研究操作条件对MR脱色的影响。在37℃温度和6.0的pH值下，在1%葡萄糖中观察到该曲霉属真菌的最佳脱色活性。此外，在重复分批实验中，当真菌生物质固定在藻酸盐凝胶中时，观察到稳定的脱色效率。这些结果表明，在韩国分离出的曲霉属真菌可用于处理含有MR染料的工业废水。
