Isolating fungus from textile wastewater and assessing their efficacy in decolorizing colors.

Abstract

Textile wastewater is different because it has a lot of synthetic dyes, salts, surfactants, and dangerous organic pollutants that pose a big risk to the environment. Conventional treatment procedures are often costly and ineffectual in removing persistent azo dyes. This study evaluated the bioremediation potential of three fungal strains,Trametes versicolor, Phanerochaete chrysosporium, and Aspergillus nige for the treatment of textile wastewater during a 14-day period. The efficacy of decolorization and the reductions in chemical oxygen demand (COD), biological oxygen demand (BOD), and total suspended solids (TSS) were thoroughly assessed. T. versicolor was the most effective of the strains tested, with 93% dye decolorization and 79% COD reduction. P. chrysosporium reduced the chemical oxygen demand (COD) by 73% and the color by 86%. A. niger reduced the color by 70% and the COD by 57%. The BOD levels went down by 67%, 62%, and 49%, while the TSS levels went down by 59%, 53%, and 42% for T. versicolor, P. chrysosporium, and A. niger, respectively. Spectrophotometric analysis revealed a substantial decrease in absorbance at λmax (520–620 nm), confirming the cleavage of azo bonds and the deterioration of aromatic structures.
These results highlight the considerable potential of white-rot fungi, particularly T. versicolor, as viable and environmentally friendly agents for the bioremediation of textile effluent.
