利用植物内生菌伙伴关系的一个有前途的领域是污染土壤和（地下）水的修复。许多植物生长促进内生菌可以帮助其宿主植物克服污染物诱导的胁迫反应，从而提供改善的植物生长。在有机污染物的植物修复过程中，植物可以进一步受益于具有适当降解途径和代谢能力的内生菌，从而更有效地降解污染物并降低挥发性污染物的植物毒性和蒸发蒸腾。对于有毒金属的植物修复，具有金属抗性/螯合系统的内生菌可以降低金属植物毒性并影响金属向地上部分的转移。此外，内生菌可以降解有机污染物和处理，甚至更好，提高提取的金属提供了有前途的方法，以提高植物修复的混合污染。
A promising field to exploit plant–endophyte partnerships is the remediation of contaminated soils and (ground) water. Many plant growth promoting endophytes can assist their host plant to overcome contaminant-induced stress responses, thus providing improved plant growth. During phytoremediation of organic contaminants, plants can further benefit from endophytes possessing appropriate degradation pathways and metabolic capabilities, leading to more efficient contaminant degradation and reduction of both phytotoxicity and evapotranspiration of volatile contaminants. For phytoremediation of toxic metals, endophytes possessing a metal-resistance/sequestration system can lower metal phytotoxicity and affect metal translocation to the above-ground plant parts. Furthermore, endophytes that can degrade organic contaminants and deal with or, even better, improve extraction of the metals offer promising ways to improve phytoremediation of mixed pollution.
