Wastewater generated from industries contains numerous contaminants, among which heavy metals (HMs) are non-degradable. This research work highlights the use of commonly used ornamental plants, Nicotiana alata L. and Petunia hydrida L., with compost (C) and peat moss (M), and rhizospheric bacterial augmentation using Pseudomonas japonica, for the phytostabilization of HMs from synthetic wastewater. After plant–soil acclimatization, plants were exposed for 6 weeks to synthetic wastewater, containing cadmium, chromium, copper, lead, nickel, and zinc concentrations (based on the HMs level of wastewaters collected from textile and pharmaceutical industry). Physiological response, biochemical status, and enzymatic fluctuations of plants and the distribution of HMs in plant parts and soil, were quantified. With the combined use (5% each v/v conditioner/soil) of C and M, in bio-augmented soil, physiological response and enzymatic status of both plants improved, with decreased stress injury due to HMs. Further, the plant HMs uptake was reduced, with better stabilization of HM in soil. For better phytostabilization of HMs in wastewater, the use of compost, peat moss, and bacterial augmentation is recommended with Nicotiana alata L. and Petunia hydrida L.

土壤改良剂和生物强化的综合应用，以增强废水中重金属的稳定性和改善 Nicotiana alata L. 和 Petunia hydrida L. 的生长。

工业产生的废水含有多种污染物，其中重金属 (HMs) 不可降解。这项研究工作重点介绍了常用观赏植物 Nicotiana alata L. 和 Petunia hydrida L. 与堆肥 (C) 和泥炭苔藓 (M) 以及使用假单胞菌增强根际细菌的用途，用于合成废水中 HMs 的植物稳定. 植物-土壤适应环境后，植物暴露于合成废水中 6 周，其中含有镉、铬、铜、铅、镍和锌的浓度（基于从纺织和制药行业收集的废水的 HMs 水平）。对植物的生理反应、生化状态和酶促波动以及 HMs 在植物部位和土壤中的分布进行量化。随着 C 和 M 的组合使用（每种 v/v 调节剂/土壤 5%），在生物增强土壤中，两种植物的生理反应和酶状态得到改善，HMs 引起的应激损伤减少。此外，植物 HMs 的吸收减少，土壤中 HM 的稳定性更好。为了更好地稳定废水中的 HM，建议在 Nicotiana alata L. 和 Petunia hydrida L. 中使用堆肥、泥炭苔和细菌增殖。
