Aromatic compounds have received widespread attention because of their threat to ecosystem and human health. However, traditional physical and chemical methods are criticized due to secondary pollution and high cost. As a result of ecological security and the ability of carbon sequestration, biodegradation approach based on microalgae has emerged as a promising alternative treatment for aromatic pollutants. In light of the current researches, the degradation efficiency of BTEX (benzene, toluene, ethylbenzene, and xylene), polycyclic aromatic hydrocarbons (PAHs), and phenolic compounds by microalgae was reviewed in this study. We summarized the degradation pathways and metabolites of p-xylene, benzo [a]pyrene, fluorene, phenol, bisphenol A, and nonylphenol by microalgae. The influence factors on the degradation of aromatic compounds by microalgae were also discussed. The integrated technologies based on microalgae for degradation of aromatic compounds were reviewed. Finally, this study discussed the limitations and future research needs of the degradation of these compounds by microalgae.
芳香族化合物因其对生态系统和人类健康的威胁而受到广泛关注。然而，由于二次污染和高成本，传统的物理和化学方法受到了批评。由于生态安全和固碳能力，基于微藻的生物降解方法作为一种有前途的芳香族污染物处理方法已经出现。鉴于目前的研究，本文综述了微藻对 BTEX（苯、甲苯、乙苯和二甲苯）、多环芳烃（PAHs）和酚类化合物的降解效率。我们总结了微藻对二甲苯、苯并[a]芘、芴、苯酚、双酚 A 和壬基酚的降解途径和代谢物。还讨论了影响微藻降解芳香族化合物的因素。综述了基于微藻的芳香族化合物降解的集成技术。最后，本文讨论了微藻降解这些化合物的局限性和未来研究需求。
