Abstract : Acquaintance of environmental issues and their increased risks, Industrial development, rehabilitation and restoration work creating a big Ecological imbalance. Pleurotus Ostreatus play a very vital role for the sustainable resource development maintaining the ecosystem by scavenging oil refinery waste that pollute the soil, air & water too .oils pollutants forming upper most close layer prevent to growing new species. Bioremediation is becoming booming due to its ecological approach. Their scavenging ability suggests their usefulness with their enzymatic activity to break down oily substances or growth on it remove pollutants. Pleurotus Ostreatus have the potential to break down oil & toxins at maximum extent.Studies includes the estimation of nutrients in oily Compound suck by pleutrotus Ostreatus cultivated on three agricultural & oil refinery waste product were carried by using Cup plate method on Soyabean oil, Coconut oil & Mustard Oils in different oil refinery& extraction shops.Result were obtained from the given oil compound at different concentrations10μl, 20μl,30μl,40μl Which also comprised the control & combined effect of oil assessed .

Soyabean oil shows maximum zone of exhibition, growth area than Coconut oil then mustard oil in the triplicates Pleurotus Ostreatus show Miraculously growth on oil as activator ,Growth on waste materials decomposition as a bioremideator [22] suggesting a link between Symbiosis and environmental cleanup.
