Heavy metal contamination is a worldwide concern and a challenge to resolve due to the toxicity poses a significant threat to all living organisms in the environment. Phytoremediation is an environmental-friendly approach to alleviate heavy metal contamination in the soil. Combining the plant and beneficial bacteria inoculant to remediate soil heavy metal is known as bacterial inoculant-assisted phytoremediation. Beneficial bacteria facilitate plant metal uptake by mobilizing the heavy metals in the soil and enhancing plant vigor. The inoculant formulations can be prepared as liquid, granules or powders. Nonetheless, the effective interaction between plant and bacteria is not promised in unsterilized soil, thus affecting the phytoremediation efficiency. The development of bacterial inoculants for phytoremediation and the effects of the inoculants in soil are overlooked in current research studies. Therefore, an ample understanding of the bacterial inoculant-assisted phytoremediation concept is pertinent to circumvent the limitations. This article discusses the relationship between beneficial bacteria inoculant and plant in different techniques of phytoremediation, recent advances in developing bacterial inoculants for phytoremediation and the fate of the inoculants in soil. The provided information in this article generates more insights on the optimization works, which ultimately leading to the possible field application.

重金属污染是一个世界性的问题，并且由于其毒性对环境中的所有生物构成重大威胁，因此需要解决该问题。植物修复是一种减轻土壤重金属污染的环保方法。将植物和有益菌接种剂结合以修复土壤重金属被称为细菌接种剂辅助植物修复。有益细菌通过动员土壤中的重金属和增强植物活力来促进植物金属吸收。孕育剂制剂可以制成液体、颗粒或粉末。尽管如此，在未经消毒的土壤中，植物与细菌之间的有效相互作用并没有得到保证，从而影响了植物修复的效率。目前的研究忽略了用于植物修复的细菌接种剂的开发以及接种剂在土壤中的影响。因此，充分了解细菌接种剂辅助植物修复的概念对于规避这些限制非常重要。本文讨论了不同植物修复技术中有益菌接种剂与植物之间的关系、开发用于植物修复的细菌接种剂的最新进展以及接种剂在土壤中的归宿。本文提供的信息对优化工作产生了更多见解，最终导致了可能的现场应用。充分了解细菌接种剂辅助植物修复概念有助于规避局限性。本文讨论了不同植物修复技术中有益菌接种剂与植物之间的关系、开发用于植物修复的细菌接种剂的最新进展以及接种剂在土壤中的归宿。本文提供的信息对优化工作产生了更多见解，最终导致了可能的现场应用。充分了解细菌接种剂辅助植物修复概念有助于规避局限性。本文讨论了不同植物修复技术中有益菌接种剂与植物之间的关系、开发用于植物修复的细菌接种剂的最新进展以及接种剂在土壤中的归宿。本文提供的信息对优化工作产生了更多见解，最终导致了可能的现场应用。
