纺织工业染料污染是当今世界面临的主要问题之一。本研究的重点是去除活性染料，Drimaren绿松石CL-B使用裂褶菌commune，一个白色腐烂真菌（WRF）牢记当前的环境条件。考察了pH值、碳源、氮源、温度、染料浓度和C/N比等因素对该工艺的影响。在pH 4.5、温度35°C、接种量3 mL、藜芦醇（介体）、葡萄糖（碳源）和硝酸铵（氮源）下获得95.45%的最大染料去除。采用酶法测定酶活性。漆酶和木质素过氧化物酶（LiP）活性较低，锰过氧化物酶（MNP）活性最高。在pH 1和313 K时，吸附量最大。染料的去除过程符合准二级动力学模型& Freundlich等温式。因此，白色腐菌有可能成为去除废水中合成染料的优良生物材料。
The pollution due to dyes from textile sector is one of the major issues faced worldwide. This study was focused on the removal of the reactive dye, Drimaren Turquoise CL-B using Schizophyllum commune, a white rot fungus (WRF) keeping in mind the current environmental conditions. Different parameters like pH, sources of carbon & nitrogen, temperature, concentration of dye and C/N ratio were used to investigate their effect on the process. Maximum dye removal of 95.45% was obtained at pH 4.5, temperature 35°C, inoculum size 3 mL, veratryl alcohol (mediator), glucose (carbon source) and ammonium nitrate (nitrogen source). The enzyme activity was determined by employing enzyme assay. Laccase and Lignin peroxidase (LiP) activity was low while Manganese peroxidase (MnP) activity was highest. Maximum bio-sorption was achieved at pH 1 and 313 K. The pseudo-2nd-order kinetic model & Freundlich isotherm was best suited for the process of removal of dye. From these data, it is concluded that white rot fungus could possibly be the excellent biomaterial for elimination of synthetic dyes from wastewater.
