“Copper-Resistant Marine Bacteria Threaten Ship Hull Coatings, Driving Need for New Biofoul” — what this page in the network covers. Marine bacteria have evolved to resist copper-based coatings long used to protect ship hulls from barnacles, algae, and other biofouling organisms. This adaptation undermines a key defense against biofouling, which increases drag, fuel consumption, and maintenance costs for the global shipping industry. The problem is widespread: copper has been a primary antifouling agent for decades, but resistant bacterial strains now survive and form biofilms that pave the way for larger organisms to attach.
Shipping companies face higher operational expenses and greater environmental impact due to increased fuel burn and greenhouse gas emissions. The development of copper resistance in marine bacteria signals an urgent need for alternative antifouling strategies, such as non-toxic surface coatings, ultrasonic systems, or biological agents.
