摘要：AbstractSynthetic dyes are extensively used in textile industries. The release of dyes into industrial effluents exert adverse impacts on biological entities such as toxicity, carcinogenicity, and mutagenicity. Biological stripping deals with the removal of dyes using microorganisms or their enzymes and chemical stripping involve the removal of dyes by using different chemicals. This study was conducted to evaluate the decolorizing efficiency of biological and chemical stripping processes in terms of economic and environmental effects. Dyed cotton fabric was subjected to both biological (fungal) and chemical stripping individually. Results indicated that the shade strength does not influence the fabric strength, but chemical and biological treatment influence the quality of cotton fabric concerning durability/bursting strength. At optimized fungal growth parameters, 61.29% color stripping was recorded, which was slightly less than chemically treated fabric (68.27%). However, chemically stripped fabric showed higher weight loss (3.76%), and strength loss (6.15%) as compared to biologically treated fabric (1.51% weight loss, 2.32% strength loss). In conclusion,Ganoderma lucidumIBL-05 presents the noteworthy capability of color stripping/dye decolorization of waste cotton fabric under optimized conditions. Based on the findings, the biological striping process is superior to chemical-based methodologies regarding the stripping percentage of dyes and the quality of the cotton fabric.
