ABSTRACT
Nosocomial and community infections and biofilm formation from bacteria has increased significantly through adaptation combined with overuse of broad spectrum antibiotics. Because the world population continues to escalate, hospitals and long-term managed care will also escalate, thereby increasing transmission of infections, lowering patients' quality of health. Another disease on the rise throughout the world is skin cancer. A treatment modality that would cause less deleterious effects on the patient would be ideal. These two seemingly different issues could be solved with one product. First an inexpensive, safe, and non-selective antimicrobial surface coating would enhance the hospital arena and a …

Polycyclic aromatic hydrocarbons (PAHs) are hydrophobic organic compounds consisting of two or more fused benzene rings. PAHs derive from many different sources including petroleum refining, wood treatment, and coal coking industries. Because of their structural stability and water insolubility, PAHs are extremely resistant to degradation. These compounds are also believed to have mutagenic, carcinogenic, and teratogenic effects. Therefore, there are currently 16 PAH compounds on the EPA's list of priority pollutants.
Many species of bacteria have the ability to breakdown these persistent pollutants. However, bioremediation strategies using these organisms have many unresolved issues. While laboratory experiments can easily demonstrate the …
