The Pharmaceuticals and Personal Care Products (PPCPs) presence at harmful levels has been identified in aquatic ecosystems all over the world. Currently, PPCPs are more common in aquatic regions and have been discovered to be extremely harmful to aquatic creatures. Waste-water treatment facilities are the primary cause of PPCPs pollution in aquatic systems due to their limited treatment as well as the following the release of PPCPs. The degree of PPCPs elimination is primarily determined by the method applied for the remediation. It must be addressed in an eco-friendly manner in order to significantly improve the environmental quality or, at the very least, to prevent the spread as well as effects of toxic pollutants. However, when compared to other methods, environmentally friendly strategies (biological methods) are less expensive and require less energy. Most biological methods under aerobic conditions have been shown to degrade PPCPs effectively. Furthermore, the scientific literature indicates that with the exception of a few extremely hydrophobic substances, biological degradation by microbes is the primary process for the majority of PPCPs compounds. Hence, this review discusses about the optimistic role of microbe concerned in the degradation or transformation of PPCPs into non/less toxic form in the polluted environment. Accordingly, more number of microbial strains has been implicated in the biodegradation/transformation of harmful PPCPs through a process termed as bioremediation and their limitations.
在世界各地的水生生态系统中，已发现存在有害水平的药品和个人护理产品（PPCPs）。目前，PPCPs在水域更为常见，并且已被发现对水生生物极其有害。废水处理设施是水生系统中PPCPs污染的主要原因，这是由于其处理能力有限以及随后PPCPs的排放。PPCPs的去除程度主要取决于所采用的修复方法。必须以环保方式解决该问题，以便显著改善环境质量，或者至少防止有毒污染物的扩散及其影响。然而，与其他方法相比，环保策略（生物方法）成本更低且能耗更少。大多数需氧条件下的生物方法已被证明能有效降解PPCPs。此外，科学文献表明，除了少数极疏水物质外，微生物的生物降解是大多数PPCPs化合物的主要过程。因此，本综述讨论了微生物在受污染环境中将PPCPs降解或转化为无毒/低毒形式方面的积极作用。相应地，越来越多的微生物菌株通过一种称为生物修复的过程参与了有害PPCPs的生物降解/转化及其局限性。
