Özet
Textile wastewaters do not only have aesthetical implications but can also be toxic when discharged into the environment without being treated. Therefore, textile waste-water must be treated. In this study, fungi isolated from soil and wastewater from a textile plant were tested for their potential to decolorize reactive textile dyes (Reactive Red H8B, Remazol Black B, and Remazol Brillant Blue R). Of the 24 isolates tested, 8 were found to have decolorization potential. The reactive dyes were decolorized up to 88.4-92.2% under static culture conditions, and up to 93.4-94.6% under agitated conditions. Aspergillus carneus was found to have the greatest decolorization efficiency. The effects of various conditions, such as agitation, initial pH, inoculum size, dye concentration, live and dead biomass, on decolorization efficiency of A. carneus were investigated. Decolorization activity was optimal at pH 5, and color removal was faster with higher amounts of inoculum. Decolorization potential of A. carneus was higher in live form (93-96%) compared to dead form (58-71%). Different concentrations of the dyes (50, 100 and 200 mg/L) were effectively removed from the media revealing extensive decolorization ability of this fungus.
