This project by Kasun Siriwardane titled “The Efficacy of Natural Antimicrobial Compounds in Antifouling and Combatting Biofilm Formation” investigates the effectiveness of natural antimicrobial compounds—tea tree oil, clove oil, and cinnamon essential oil—in preventing biofouling on stainless-steel surfaces in marine environments. Traditional chemical antifouling methods harm marine ecosystems such as fish, and exacerbate water quality, necessitating eco-friendly alternatives. The study submerged stainless-steel cylinders coated with the oils, a chemical agent, and a control in water for 74 hours. Tree Tea oil and Cinnamon Oil demonstrated significant antifouling potential, reducing biofilm accumulation compared to the control. These findings highlight the promise of natural compounds as sustainable antifouling agents, and prompt further long-term studies.
