Mycoremediation of garbage contaminated municipal soil and garage contaminated oil soil using Pleurotus Ostreatus – A comparative study

Municipal solid waste dumped on soil leads to accumulation of heavy metals, inorganics and halogenated organics, thereby deterring growth of plant with a reckonable loss in its nutritional quality. In this study, heavy metal uptake potential of mushroom and degradation of polyaromatic compounds by P...

Description
Summary:Municipal solid waste dumped on soil leads to accumulation of heavy metals, inorganics and halogenated organics, thereby deterring growth of plant with a reckonable loss in its nutritional quality. In this study, heavy metal uptake potential of mushroom and degradation of polyaromatic compounds by Pleurotus Ostreatus was studied in garbage contaminated municipal soil and garage contaminated oil soil. Amalgamation of nutrients and soil in five layer sandwich bioreactor of polypropylene packing offered the least lag phase where a degradation efficiency of 68% and 81% were obtained for lead and nickel respectively. Organic contaminants of the oil soil like 2,6 diethyl butyl phenol and total petroleum hydrocarbon were degraded upto maximum of 90 and 97.5% respectively. The bioaccumulation factor greater than 1 indicates the recovery of the metal in the fruiting body. The efficiency and effectiveness of remediation treatment was compared to phytoremediation, carried out using fenugreek on the contaminated soil. Garbage and garage contaminant degradation efficiency of mycoremediation was higher than phytoremediation where exponential first order kinetics was observed
