Endophytic microorganisms contribute significantly to water bioremediation by enhancing pollutant degradation and supporting aquatic plant health and resilience by releasing bioactive compounds and enzymes. These microorganisms inhabit plant tissues without causing disease or any noticeable symptoms. Endophytes effectively aid in eliminating contaminants from water systems. Nanoparticles serve as potent enhancers in bioremediation processes, augmenting the efficiency of pollutant degradation by increasing surface area and bioavailability, thereby improving the efficacy and rate of remediation. Their controlled nutrient release and ability to stabilize endophytic colonization further contribute to the enhanced and sustainable elimination of contaminated environments. The synergistic effect of endophytes and nanoparticles in water remediation has been widely explored in recent studies, revealing compelling outcomes. Water pollution poses significant threats to human health, ecosystems, and economies; hence, the sixth global goal of the Sustainable Development Agenda 2030 of the United Nations aims to ensure the availability and sustainable management of water resources, recognizing their crucial importance for current and future generations. Conventional methods for addressing water pollution exhibit several limitations, including high costs, energy-intensive processes, the production of hazardous by-products, and insufficient effectiveness in mitigating emerging pollutants such as pharmaceuticals and microplastics. Noticeably, there is an inability to effectively remove various types of pollutants, thus resulting in incomplete purification cycles. Nanoparticle-enhanced water bioremediation offers an innovative, eco-friendly alternative for degrading contaminants. A growing body of research has shown that integrating endophytic microorganisms with nanoparticles for water bioremediation is a potent and viable alternative. This review examines the potential of using endophytic microorganisms and nanoparticles to enhance water remediation, exploring their combined effects and applications in water purification. The paper also provides an overview of synthetic methods for producing endophyte-nanoparticle composites to optimize their remediation capabilities in aqueous environments. The final section of the review highlights the constraints related to integrating endophytes with nanoparticles.
内生微生物通过释放生物活性化合物和酶来增强污染物降解能力,并支持水生植物的健康和恢复力,从而对水的生物修复做出重大贡献。这些微生物栖息在植物组织中,不会引起疾病或任何明显的症状。内生菌有效地帮助从水系统中消除污染物。纳米颗粒在生物修复过程中是强有力的增强剂,通过增加表面积和生物利用度来提高污染物降解的效率,从而提高修复的效果和速度。它们的受控养分释放和稳定内生菌定殖的能力进一步有助于增强和可持续地消除受污染的环境。内生菌和纳米颗粒在水修复中的协同作用在最近的研究中得到了广泛的探索,揭示了令人信服的结果。水污染对人类健康、生态系统和经济构成重大威胁;因此,联合国 2030 年可持续发展议程的第六个全球目标旨在确保水资源的可用性和可持续管理,认识到它们对当前和未来几代人的至关重要性。解决水污染的传统方法存在几个局限性,包括成本高、能源密集型过程、产生危险的副产品以及在减轻新兴污染物(如药品和微塑料)方面的效果不足。值得注意的是,无法有效地去除各种类型的污染物,从而导致净化循环不完整。纳米颗粒增强的水生物修复为降解污染物提供了一种创新的、环保的替代方法。越来越多的研究表明,将内生微生物与纳米颗粒结合用于水生物修复是一种有效且可行的替代方法。本综述探讨了利用内生微生物和纳米颗粒增强水修复的潜力,研究了它们在水净化中的联合作用和应用。本文还概述了用于生产内生体-纳米颗粒复合材料的合成方法,以优化它们在水相环境中的修复能力。综述的最后一节强调了将内生体与纳米颗粒整合的限制。
