Bioremediation of Crude Oil with Three Edible Mushroom Species

Crude oil is a severe environmental problem because of its high organic content, antimicrobial and phytotoxic phenol compounds, and the difficulty of cleaning and containing spills. The goal of this experiment was to determine if three common, edible mushroom species of Cortinarius violaceus, Gyroporous cyanescens and Fistulina hepatica are capable of metabolizing petroleum for remedial purposes. A lab experiment was set up and our experimental treatments comprised of three fungal species of C. violaceus, G.cyanescenes, and F. hepatica and the oil concentration was 0 (control), 0.5, 1, and 2 mL in each petri dish. The treatments were arranged as a completely randomized design with three replications. The results of the experiment showed that C. violaceus was the most efficient at utilizing crude oil for growth over the twenty-day period.
