Nano-enabled strategies to reduce the presence of contaminants of emergent concern in aquatic environments
Contaminant of emerging concern (CECs) such as antibiotics, pathogens and antimicrobial resistant (AMR) bacteria in water bodies associated to intensive fish and inland animal farming, represent a great threat to the environment and human health.
A common issue with the fish cage nets is the formation of biofoulings and biofilms, acting as a bacteria reservoir and reducing the water flow inside the cages. This implies frequent net cleaning and replacement, or the use of expensive antifouling agents that increase the operating costs of fish farming. Nano-materials emerged as novel antimicrobial agents with demonstrated efficacy against AMR bacteria. AMROCE aims at reducing antibiotic pollution and spread of AMR bacteria in the entire water cycle through a platform of novel antibiotic-free antimicrobial products. AMROCE will develop antimicrobial/antibiofilm fish cage nets and wastewater filtration membranes through polymer and surface nano-engineering. Marine-derived antimicrobial agents and antibiofilm enzymes will be nano-formulated as alternative to antibiotics for fish and animal feed supplement. Human and environmental nanosafety during the manufacturing and use of the novel nanotechnology-embedded products will be continuously evaluated to anticipate nanosafety issues.
