The acceleration of industrial development and urban expansion has led to a significant increase in flue gas emissions, posing a significant risk to human health and ecosystems. Recent studies have elucidated the significant potential of microalgae in the domain of sustainable industrial flue gas treatment. However, the inherent multifaceted factors within flue gas exert inhibitory effects on microalgal growth, thereby diminishing the overall system efficacy. Therefore, it is necessary to systematically analyze the flue gas components and propose complete intermediate treatment steps to alleviate their stressful effects on microalgae. Concurrently, to address the intrinsic limitations of the systemic functionality and enhance the applicability of microalgal biotechnology in industrial flue gas treatment, this review proposes a series of innovative solutions and strategies aimed at improving carbon fixation efficiency and lipid productivity of microalgae during flue gas treatment. In addition, the feasibility and potential limitations of these strategies in industrial applications are also discussed. Furthermore, through systematic comparative analysis, the optimal scheme and development trend of industrial flue gas emission reduction technology are explored. This comprehensive review not only establishes a theoretical foundation for the application of microalgae in industrial flue gas treatment, but also offers valuable insights for future research directions in related fields.
工业发展和城市扩张的加速导致烟气排放量显著增加，对人类健康和生态系统构成重大风险。最近的研究阐明了微藻在可持续工业烟气处理领域的巨大潜力。然而，烟气中固有的多方面因素对微藻生长产生抑制作用，从而降低了整个系统的功效。因此，有必要系统地分析烟气成分，并提出完整的中间处理步骤，以减轻其对微藻的压力影响。同时，为了解决系统功能的固有局限性，提高微藻生物技术在工业烟气处理中的适用性，本综述提出了一系列创新解决方案和策略，旨在提高烟气处理过程中微藻的碳固定效率和脂质生产率。此外，还讨论了这些策略在工业应用中的可行性和潜在局限性。此外，通过系统的比较分析，探索了工业烟气减排技术的最佳方案和发展趋势。这一全面综述不仅为微藻在工业烟气处理中的应用奠定了理论基础，也为相关领域未来的研究方向提供了有价值的见解。
