[2] Bioremediation is the process by which polluted soil, water, and other natural materials are treated to encourage growth of microorganisms which can degrade contaminants.
Q8 was chosen for study as a bioremediator due to its ability to grow on media which includes the polycyclic aromatic hydrocarbons (PAHs) naphthalene and pyrene.
[4] Sixteen PAHs are listed as priority pollutants by the U.S. Environmental Protection Agency because of their association with cancer in aquatic animals and increased mutagenicity of sediments.
[2] PAH-degrading microorganisms are commonly found in polluted areas such as oil wells, where they utilize PAHs as their sole carbon and energy source.
[2] Q8 can also significantly reduce the viscosity of oil, making it more soluble in water and easier to utilize by other bacteria in a process known as petroleum bioremediation.
