Phthalate esters (PAEs) are hazardous organic compounds that are widely added to plastics to enhance their flexibility, temperature, and acidic tolerance. The increase in global consumption and the corresponding environmental pollution of PAEs has caused broad public concerns. As most PAEs accumulate in soil due to their high hydrophobicity, composting is a robust remediation technology for PAE-contaminated soil (efficiency 25%-100%), where microbial activity plays an important role. This review summarized the roles of the microbial community, biodegradation pathways, and specific enzymes involved in the PAE degradation. Also, other green technologies, including biochar adsorption, bioaugmentation, and phytoremediation, for PAE degradation were also presented, compared, and discussed. Composting combined with these technologies significantly enhanced removal efficiency; yet, the properties and roles of each bacterial strain in the degradation, upscaling, and economic feasibility should be clarified in future research.
邻苯二甲酸酯(PAEs)是一类危害性有机化合物,被广泛添加到塑料中以增强其柔韧性、温度和耐酸性。随着 PAEs 全球消耗量的增加及其所导致的环境污染,引起了广泛的公众关注。由于 PAEs 的高疏水性,大部分 PAEs 会在土壤中积累,堆肥是一种修复 PAE 污染土壤的有效技术(效率为 25%-100%),其中微生物活性起着重要作用。本综述总结了 PAE 降解过程中微生物群落、生物降解途径和相关特定酶的作用。此外,还介绍、比较和讨论了其他绿色技术,如生物炭吸附、生物强化和植物修复,用于 PAE 降解。堆肥与这些技术相结合可以显著提高去除效率;然而,在未来的研究中,应该阐明每个细菌菌株在降解、扩大规模和经济可行性方面的特性和作用。
