This review explores eco-engineered bioremediation strategies, focusing on the pivotal role of rhizosphere-associated microorganisms in detoxifying heavy metals. Rhizobacteria deploy diverse mechanisms—including biosorption, bioaccumulation, biotransformation, and biomineralization—to immobilize or convert toxic metals, with their efficiency strongly influenced by environmental factors such as pH and metal speciation. Plant Growth-Promoting Rhizobacteria (PGPR) further enhance phytoremediation by mitigating metal-induced phytotoxicity and promoting plant resilience under stress. Various scalable approaches, including in-situ and ex-situ remediation techniques, biosorbents, microbial consortia, and genetically engineered microbes (GEMs), show promising potential but raise essential ecological and regulatory concerns. Key challenges such as scalability, environmental variability, and the possible formation of toxic intermediates must be carefully addressed. Advances in omics technologies and a deeper exploration of native microbial communities offer promising avenues to optimize bioremediation outcomes. Moreover, a detailed understanding of plant–microbe interactions and the role of secondary metabolite signalling in the rhizosphere is essential to improve remediation efficiency. Future strategies should prioritize the application of functional genomics, developing bioinoculants tailored to specific environmental conditions, and implementing robust ecological risk assessments for GEMs. This review underscores the need for a multidisciplinary approach- integrating microbial ecology, plant sciences, and environmental engineering- to drive the development of sustainable, effective HM remediation technologies worldwide.</div></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":"9 ","pages":"Article 100297"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144068769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines emerging technologies for POP remediation, assessing conventional methods while emphasizing the potential of innovative approaches. Advanced technologies, including nanotechnology and advanced oxidation processes (AOPs), show potential for effective, cost-efficient and environmentally friendly POP degradation. Among AOPs, methods such as UV/H<sub>2</sub>O<sub>2</sub>, Fenton’s reaction, photo-Fenton, UV/Ozone, and photocatalysis with semiconductors like TiO<sub>2</sub> are particularly effective in breaking down POPs into less harmful substances. Nanotechnology-based methods provide high efficiency, selectivity, and reduced environmental impact, while photocatalysis offers a sustainable and eco-friendly approach to POP degradation. To enhance remediation effectiveness, integrating innovative materials, optimized processes, and artificial intelligence (AI) is crucial. Advancements in eco-friendly nanomaterials, hybrid AOPs, and AI-driven process optimization can significantly improve degradation efficiency, selectivity, and sustainability. Future research should focus on scaling up these technologies, improving cost-effectiveness, and incorporating AI-powered smart monitoring systems for long-term environmental management. A holistic and sustainable remediation strategy must also align with circular economy principles, promote eco-friendly innovations, and address the influence of climate change on POP behavior.
