Abstract:
Mycoremediation techniques are being introduced to remove pollutants as substitutes for physical and chemical methodologies as it is cheapest, sustainable and environmentally friendly. For example, use of spent mushroom substrate (SMS) that can remediate contaminated soil. In this work, SMSs of Agaricus bisporus and Pleurotus ostreatus were evaluated for mycoremediaton of diesel contaminated soil. The mycoremediation test was carried out by mixing diesel in mushroom compost. Both mushroom species were grown separately on different levels of diesel. After cultivation of both species, SMS was mixed with garden soil and allowed to decompose. After decomposition, substrate obtained was used as experimental growth media for Zea mays and Spinacia oleracea along with control setup. Physical and chemical properties of plant growth media, morphological and physiochemical parameters of test plants was measured. The result showed decrease in organic matter, organic carbon and pH while increase in potassium and water retaining capacity of remediated plant growth media as compared to control. Improvement in growth and physiochemical parameters (chlorophyll, carbohydrate and protein content) was observed in both test plants grown in remediated media. It was also observed that Agaricus bisporus has more potential of mycoremediation than Pleurotus ostreatus. These results showed the effectiveness of SMS to remove diesel from contaminated soil and its suitability for the growth of Spinacia oleracea and Zea mays. In this regard, this technique is beneficial for the farmers as they can sale the harvested mushrooms, remove diesel pollutant from contaminated land and use SMS as organic fertilizer after processing.
