چکیده
White rot fungus Marasmius sp. BBKAV79 (GenBank accession number-KP455496, KP455497) exhibited decolourization and degradation of Navy blue HER dye (concentration 50 mg l-l) within 24 h under shaking condition. In the present study, various investigated parameters like initial dye concentration, pH, temperature, carbon and nitrogen sources were optimized to develop a faster decolourization process by Marasmius sp. BBKAV79. High-performance liquid chromatography, Fourier transform infrared spectroscopy and gas chromatography and mass spectroscopy analysis of the extracted product confirmed the biodegradation of Navy blue HER. The microbial toxicity and phytotoxicity assay revealed that the degradation of Navy blue HER produced nontoxic metabolites.

In many industrial areas such as in food, pharmaceutical, cosmetic, printing, and textile, the use of synthetic dyes has been integral with products such as azo dye, anthrax, and dyestuffs. As such, these industries produce a lot of waste by-products that could contaminate the environment. Bioremediation, therefore, has become an important emerging technology due to its cost-sustainable, effect...
