Description
Summary:Pleurotus ostreatus (Jacq.: Fr.) P. Kumm. is one of the edible mushrooms currently gaining attention as environmental restorer. The present study explores the potential of P. ostreatus (Jacq.: Fr.) P. Kumm. in degradation of textile dyes and effluents. The mushroom cultivation was carried out using paddy bed as substrate. The fully grown mushroom fruit bodies were used as a bioremediation agent against two industrially important azo dyes such as nylon blue and cotton yellow and few effluents collected from various textile industries in Karnataka, India. The ideal growth parameters such as temperature, pH, and dye concentrations for effective degradation were carried out. One of the main enzymes, laccase, responsible for biodegradation, was partially characterized. The degradation was found to be ideal at pH 3.0 and temperature at 26–28 °C. This study demonstrated a percentage degradation of 78.10, 90.81, 82.5, and 64.88 for dye samples such as nylon blue (50 ppm), cotton yellow (350 ppm), KSIC effluents, and Ramanagar effluents at 28 °C within 15th days respectively in comparison with other temperature conditions. Similarly, a percentage degradation of 35.99, 33.33, 76.13 and 25.8 for nylon blue (50 ppm), cotton yellow (350 ppm), Karnataka Silk Industries Corporation (KSIC) effluents and Ramnagar effluents were observed at pH 3.0 within 15 days, respectively (p
