Abstract

In the present study, growth performance, antioxidant activities and cadmium (Cd) accumulation in eco-friendly bacterial consortium inoculated Mentha arvensis grown in Cd contaminated soils were evaluated. Eco-friendly bacterial consortium inoculation significantly enhanced growth, biomass and antioxidant efficacy of M. arvensis plants grown in contaminated soil, i.e. wastewater irrigated and Cd-spiked soils over the non-inoculated plants (p < 0.05). Cd accumulation in roots, stems and leaves of M. arvensis inoculated with eco-friendly bacterial consortium decreased significantly as compared to plant without bacterial consortium (p < 0.05) in wastewater irrigated (5.3%, 48.5% and 5.8%, respectively) and Cd spiked (2.2%, 20.9% and 27.1%, respectively) soils. Thus, the present study concludes that application of Cd resistant eco-friendly bacterial consortium in polluted soils could be helpful in improving growth of M. arvensis and preventing entry of Cd in food chain.

在污染土壤中生长的薄荷接种细菌联合体的镉积累、生长性能和抗氧化特性

本研究评估了在镉污染土壤中生长的薄荷接种生态友好细菌群后的生长表现、抗氧化活性和镉（Cd）积累情况。与未接种生态友好细菌群的植物相比，接种生态友好细菌群能显著提高生长在污染土壤（即废水灌溉土壤和加镉土壤）中的薄荷植物的生长、生物量和抗氧化功效（p < 0.05）。在有废水灌溉的土壤（分别为 5.3%、48.5% 和 5.8%）和有镉污染的土壤（分别为 2.2%、20.9% 和 27.1%）中，接种了环保型细菌群的 M. arvensis 的根、茎和叶中的镉积累量与未接种细菌群的植物相比明显减少（p < 0.05）。因此，本研究得出结论，在污染土壤中应用抗镉生态友好型细菌群有助于改善 M. arvensis 的生长，防止镉进入食物链。
