Current Approaches to Bioremediation of Newly Discovered Contaminants
AI summary Read the abstract
This review surveys bioremediation strategies—using microbes, plants, and enzymes—for degrading or immobilizing emerging contaminants including microplastics, pharmaceuticals, and PFAS that conventional treatment systems fail to eliminate. Biological approaches offer sustainable, lower-energy alternatives to chemical treatment, though scaling them up to handle the volume and variety of contaminants entering waterways remains an active challenge.
The increasing prevalence of emerging contaminants—such as pharmaceuticals, personal care products, pesticides, endocrine-disrupting chemicals, microplastics, and per- and polyfluoroalkyl substances (PFAS)—poses a significant challenge to traditional...

Role of Microbial Enzymes for the Removal of Emerging Contaminants: An Approach for Sustainable Environment
AI summary Read the abstract
Microbial enzymes—including laccases, peroxidases, and plastic-degrading hydrolases—are being explored as tools to break down microplastics, pharmaceuticals, and pesticides that conventional treatment plants leave behind. Enzyme-based remediation offers a low-energy, targeted approach to dismantling persistent pollutants, and advances in this field could eventually enable biological cleanup of microplastic-contaminated soils and waterways at scale.
