Bacterial biofilm is a structured bacterial community enclosed within a three-dimensional polymeric matrix, governed by complex signaling pathways, including two-component systems, quorum sensing, and c-di-GMP, which regulate its development and resistance in challenging environments. The genetic configurations within biofilm empower bacteria to exhibit significant pollutant remediation abilities, offering a promising strategy to tackle diverse ecological challenges and expedite progress toward Sustainable Development Goals (SDGs). Biofilm-based technologies offer advantages such as high treatment efficiency, cost-effectiveness, and sustainability compared to conventional methods. They significantly contribute to agricultural improvement, soil fertility, nutrient cycling, and carbon sequestration, thereby supporting SDG 1 (No poverty), SDG 2 (Zero hunger), SDG 13 (Climate action), and SDG 15 (Life on land). In addition, biofilm facilitates the degradation of organic-inorganic pollutants from contaminated environments, aligning with SDG 6 (Clean water and sanitation) and SDG 14 (Life below water). Bacterial biofilm also has potential applications in industrial innovation, aligning SDG 7 (Affordable and clean energy), SDG 8 (Decent work and economic growth), and SDG 9 (Industry, innovation, and infrastructure). Besides, bacterial biofilm prevents several diseases, aligning with SDG 3 (Good health and well-being). Thus, bacterial biofilm-mediated remediation provides advanced opportunities for addressing environmental issues and progressing toward achieving the SDGs. This review explores the potential of bacterial biofilms in addressing soil pollution, wastewater, air quality improvement, and biodiversity conservation, emphasizing their critical role in promoting sustainable development.
细菌生物膜是一种由三维聚合物基质包裹的结构化细菌群落，由复杂的信号通路控制，包括双组分系统、群体感应和 c-di-GMP，它们调节其在挑战性环境中的发育和抗性。生物膜内的遗传结构赋予细菌显著的污染物修复能力，为应对各种生态挑战提供了一种有前途的策略，并加速实现可持续发展目标（SDGs）。与传统方法相比，基于生物膜的技术具有处理效率高、成本效益高和可持续性等优势。它们为农业改良、土壤肥力、养分循环和碳固存做出了重大贡献，从而支持可持续发展目标 1（消除贫困）、目标 2（零饥饿）、目标 13（气候行动）和目标 15（陆地生物）。此外，生物膜有助于从污染环境中降解有机-无机污染物，与可持续发展目标 6（清洁水和卫生设施）和目标 14（水下生物）相一致。细菌生物膜在工业创新方面也有潜在的应用，与可持续发展目标 7（负担得起的清洁能源）、目标 8（体面工作和经济增长）和目标 9（工业、创新和基础设施）相一致。此外，细菌生物膜可以预防几种疾病，与可持续发展目标 3（良好健康与福祉）相一致。因此，细菌生物膜介导的修复为解决环境问题和实现可持续发展目标提供了先进的机会。本综述探讨了细菌生物膜在解决土壤污染、废水、空气质量改善和生物多样性保护方面的潜力，强调了它们在促进可持续发展方面的关键作用。
