Microbes as Biocatalysts of Marine Micropollutants
Summary
This review examines how marine microorganisms can serve as biocatalysts to break down micropollutants including industrial chemicals, pharmaceuticals, and microplastics in ocean environments. The study highlights advances in synthetic biology and genomics that are improving microbial efficiency for targeted bioremediation, while noting the need for cooperation among scientists, policymakers, and industry to address implementation challenges.
Marine micropollutants, which are trace contaminants originating from human activities like industrial chemicals, pharmaceuticals, pesticides, heavy metals, and microplastics, represent a growing danger to marine ecosystems and human health. Although present in low concentrations, these pollutants endure in marine settings, resulting in bioaccumulation, biomagnification, and toxic effects on marine life. This disturbs ecosystems and threatens apex predators, including humans. Main sources consist of agricultural runoff, industrial emissions, and atmospheric deposition. Once present in marine environments, micropollutants impact marine organisms via toxicity and hormonal disturbances. Microbial biocatalysis provides a sustainable approach to reduce these effects, as bacteria and fungi convert dangerous compounds into safer substances. Progress in synthetic biology, genomics, and metabolomics is enhancing microbial efficiency, facilitating targeted bioremediation across various marine environments. Successful bioremediation necessitates cooperation among scientists, government officials, and businesses to tackle issues like pollutant bioavailability, the intricacies of marine ecosystems, and possible ecological hazards posed by modified microorganisms. Ongoing monitoring and evaluation are crucial to guarantee the safety and sustainability of these interventions. This research enhances knowledge of marine micropollutants and microbial remediation, advocating for strategies to reduce pollution, preserve ocean health, and ensure ecological and human welfare for future generations.
