Microbial-driven nature-based solutions for environmental antimicrobial resistance and emerging contaminants: mechanisms, platform trade-offs, and decision framework
Abstract
Introduction: Antimicrobial resistance (AMR) and emerging contaminants (ECs), including pharmaceuticals, personal care products, microplastics, and endocrine-disrupting chemicals, pose interconnected threats to environmental and human health. Nature-based solutions (NbS) have emerged as sustainable and cost-effective approaches for mitigating these challenges through ecosystem-driven processes.
Methods: This review follows a PRISMA-guided narrative-systematic synthesis of literature published between 2000 and 2024, using data sources including Scopus, Web of Science, and PubMed. The analysis integrates evidence on microbial mechanisms, NbS platform performance, and environmental AMR-EC interactions.
Results: The synthesis highlights that microbial-driven NbS exploit metabolic diversity, functional plasticity, and plant-microbe interactions to degrade, transform, immobilize, or eliminate contaminants in soil, water, and wastewater systems. Advances in microbial ecology, synthetic biology, and omics approaches have enabled the design of functional microbial consortia capable of targeting antibiotic residues, resistance genes, and recalcitrant pollutants. NbS platforms such as constructed wetlands, rhizosphere-based systems, biofilters, and microbial electrochemical technologies demonstrate variable performance influenced by microbial diversity, redox processes, and system design. However, trade-offs exist, including the potential for microbial biofilms to act as reservoirs of…
