Persistent organic pollutants (POPs), including organochlorine pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzo-p-furans, pose significant hazards to the environment and living organisms. This concise review aims to consolidate knowledge on the biological processes involved in removing POPs from wastewater, an area less explored compared to conventional physico-chemical methods. The focus is on the potential of various aerobic and anaerobic microorganisms, fungi, and bacteria for efficient bioremediation, mitigating or eradicating the deleterious effects of these chemicals. The review scrutinizes individual bacterial strains and mixed cultures engaged in breaking down persistent organic pollutants in water, highlighting promising results from laboratory investigations that could be scaled for practical applications. The review concludes by underscoring the opportunities for exploring and advancing more sophisticated bioremediation techniques and optimized bioreactors. The ultimate goal is to enhance the efficiency of microbial-based strategies, implicitly reducing the environmental impact of persistent chemicals.
持久性有机污染物（POPs），包括有机氯农药、多环芳烃、多氯联苯、多氯二苯并对二恶英和多氯二苯并呋喃，对环境和生物体构成重大危害。本简要综述旨在整合有关从废水中去除POPs所涉及的生物过程的知识，与传统物理化学方法相比，这一领域的探索较少。重点在于各种好氧和厌氧微生物、真菌和细菌进行高效生物修复、减轻或消除这些化学物质有害影响的潜力。该综述审视了参与分解水中持久性有机污染物的单个细菌菌株和混合培养物，突出了实验室研究中可能扩大规模用于实际应用的有前景的结果。综述最后强调了探索和推进更复杂的生物修复技术及优化生物反应器的机会。最终目标是提高基于微生物的策略的效率，含蓄地减少持久性化学物质对环境的影响。
