摘要:Water pollution caused by industrial waste discharges has become an alarming trend worldwide, while dyeindustries are considered as the most polluting among all others. In recent years, bio-treatment took attraction inremoving the unwanted colour and toxicity of dyes than other conventional treatment processes. The release of dyes into environment is of great concerned due to color, toxicity, mutagenicity and carcinogenicity of the dye, considerableattention has been given in evaluating the capability of microorganism in decolourisation and degradation diazo dye.The present study fungi were inoculated on different solid media to attain biodegradability of a diazo dye used for thecoloration of paper products. For the solid, to be employed as media, special characteristics are needed with regards toadsorption capacity for concentrating substrate within the cell environment and an adequate particle size and surfacetexture for assuring fungal colonization. These factors were in different pH, temperature, incubation period, inoculumsizes, carbon sources, nitrogen sources and different concentrations of yeast extract. In the present investigation theability of heat killed fungus Aspergillus terreus to adsorb the dyes Methylene blue and Congo red was investigated.The removal of the dyes Congo red and Methylene Blue from aqueous solutions on the fungal A. terreus wasdemonstrated by a series of batch experiments.
