近年来，考虑到多氯联苯在环境中的毒性、致癌性和持久性，微生物降解和生物修复方法得到了广泛的研究。在这个方向上，随着生物过程的优化，不同的分解代谢酶已经被鉴定和报道用于不同的多氯联苯同系物的生物降解。对多氯联苯降解菌的基因组分析有助于更好地了解它们的代谢潜力和对压力条件的适应。然而，这一地区的许多石头都没有被挖掘出来。例如，不可培养微生物在多氯联苯降解中的作用和多样性仍未得到充分了解。提高对这方面的认识和理解将为改进生物修复技术开辟新的途径，这将带来经济、环境和社会效益。本文重点介绍了土壤中多氯联苯生物修复的最新进展。实践证明，生物修复是包括生物刺激、生物强化、植物修复、根际修复等在内的最有效和最具创新性的技术，是污染治理的典范。最近，转基因植物和转基因微生物已被证明是多氯联苯生物修复方面的革命性进展。此外，还讨论了其他重要和方面的问题，如使用化学/物理制剂进行预处理以增强生物降解性。已努力确定挑战、研究差距和必要的方法，以便今后在实地条件下利用这些方法成功地利用生物修复。重点研究了生物修复技术的质量/效率及其成本，这决定了生物修复技术的最终可接受性。
In recent years, microbial degradation and bioremediation approaches of polychlorinated biphenyls (PCBs) have been studied extensively considering their toxicity, carcinogenicity and persistency potential in the environment. In this direction, different catabolic enzymes have been identified and reported for biodegradation of different PCB congeners along with optimization of biological processes. A genome analysis of PCB-degrading bacteria has led in an improved understanding of their metabolic potential and adaptation to stressful conditions. However, many stones in this area are left unturned. For example, role and diversity of uncultivable microbes in PCBs degradation is still not fully understood. Improved knowledge and understanding on this front will open up new avenues for improved bioremediation technologies which will bring economic, environmental and societal benefits. This article highlights on recent advances in bioremediation of PCBs in soil. It is demonstrated that bioremediation is the most effective and innovative technology which includes biostimulation, bioaugmentation, phytoremediation, rhizoremediation etc. and acts as a model solution for pollution abatement. More recently, transgenic plants and genetically modified microorganisms have proved to be revolutionary in the bioremediation of PCBs. Additionally, other important and aspects such as pretreatment using chemical/physical agents for enhanced biodegradation are also addressed. Efforts have been made to identify challenges, research gaps and necessary approaches which in future can be harnessed for successful use of bioremediation under field conditions. Emphases have been given on the quality/efficiency of bioremediation technology and its related cost which determines its ultimate acceptability.
