Decolourization and mycoremediation of Azo dye, Congo red, by Pleurotus Sajorcaju

Abstract

Dye-containing effluents are particularly difficult to remove since they ultimately have a very high water solubility, are brightly colored, and may be easily seen. The release of these effluents into aquatic ecosystems and their effective eviction from the textile industry continue to be significant environmental challenges because the harmful complexes produced (mutagenic and carcinogenic) affect the solubility of gases in water bio-recalcitrant characteristics and their effects on the ecosystem.

These poisonous substances are bioaccumulated by aquatic organisms, which subsequently use biomagnification to spread the toxicity to other species. Various chemicals have been employed to degrade azo dyes, including adsorption, precipitation, coagulation, electrocoagulation, electrocoagulation/electro flotation electrochemical degradation.

However, these decolorization processes are expensive and frequently produce amine residues. Biodegradation has proven successful, quick, and environmentally friendly, converting pollutants wholly or partially into stable, non-toxic compounds.
