Resumen:

Bioremediation of contaminated waters is an essential strategy to address pollution from various sources, such as industry, agriculture, and urban activities. This approach employs biological agents, including plants, microorganisms, and their enzymes, to detoxify and remove pollutants from aquatic environments. Bioaugmentation, involving the introduction of specialized cleanup microorganisms, is a significant technique, often requiring genetic engineering and extensive testing to ensure the microorganisms can survive and perform effectively in the target environment. Phytoremediation, where plants are used to absorb and degrade contaminants, is another crucial strategy. Contaminants affecting water bodies include oil, heavy metals, persistent organic pollutants (POPs), and agricultural chemicals, originating from point sources like factories and wastewater treatment plants, as well as non-point sources such as urban runoff and atmospheric deposition. The negative impacts of these contaminants range from aesthetic concerns to severe threats to human health and ecosystems. Bioremediation harnesses the natural detoxifying abilities of microorganisms and plants. Bacteria and fungi play a crucial role in transforming and detoxifying a broad spectrum of pollutants. Techniques like biostimulation enhance the activity of native microorganisms by adding nutrients or biosurfactants, facilitating the degradation of hydrocarbons and other contaminants. Phytoremediation utilizes plants to extract, stabilize, and degrade pollutants, providing a cost-effective and environmentally friendly solution. Success cases of bioremediation, such as the treatment of the Exxon Valdez oil spill and the recovery of Lake Washington from sewage pollution, demonstrate the effectiveness of these strategies. Challenges remain, including optimizing treatment efficiency and addressing emerging contaminants. However, ongoing research and technological advancements continue to improve the sustainability and applicability of bioremediation for large-scale environmental cleanup efforts. © 2025 Bentham Science Publishers.
