The increase in worldwide water contamination with numerous pharmaceutical contaminants (PCs) has become an emerging environmental concern due to their considerable ecotoxicities and associated health issues. Microalgae-mediated bioremediation of PCs has recently gained scientific attention, as microalgal bioremediation is a solar-power driven, ecologically comprehensive, and sustainable reclamation strategy. In this review, we comprehensively describe the current research on the possible roles and applications of microalgae for removing PCs from aqueous media. We summarize several novel approaches including constructing microbial consortia, acclimation, and cometabolism for enhanced removal of PCs by microalgae, which would improve practical feasibility of these technologies. Some novel concepts for degrading PCs using integrated processes and genetic modifications to realize algal-based bioremediation technologies are also recommended.
由于其相当大的生态毒性和相关的健康问题，世界范围内的水受到越来越多的药物污染物 (PCs) 的污染，这已成为一个新的环境关注点。由于微藻生物修复是一种太阳能驱动的、生态全面的、可持续的开垦策略，因此，利用微藻介导的生物修复来去除 PCs 最近引起了科学界的关注。在这篇综述中，我们全面描述了目前关于微藻从水介质中去除 PCs 的可能作用和应用的研究。我们总结了几种新方法，包括构建微生物群落、驯化和共代谢，以增强微藻对 PCs 的去除，这将提高这些技术的实际可行性。还建议了一些使用集成工艺和遗传修饰来实现基于藻类的生物修复技术来降解 PCs 的新概念。
