Cadmium Accumulation, Growth Performance and Antioxidant Properties of Bacterial Consortium Inoculated Mentha arvensis L. Grown in Polluted Soil
National Academy Science Letters - Trang 1-4 - 2024
Tóm tắt
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.
