Bacterial Population Of Pteris Vittata With Potentials For Bioremediation Of Arsenic Rich Soils And Plant Growth Promotion
In soil environments, certain bacteria can withstand arsenic-induced stress and play vital roles in agriculture as plant growth-promoting rhizobacteria (PGPR). The bacteria enhance plant growth and contribute to the bioremediation of toxic arsenic in soils. This process also involves a selected grou...

| description | In soil environments, certain bacteria can withstand arsenic-induced stress and play vital roles in agriculture as plant growth-promoting rhizobacteria (PGPR). The bacteria enhance plant growth and contribute to the bioremediation of toxic arsenic in soils. This process also involves a selected group of plants known as hyperaccumulators, such as Pteris vittata, which enhance the efficiency of arsenic removal from the soil. Various methods are being used to cleanse the environment from the adverse effects of arsenic pollutant, but most of these methods are not cost-effective and have very poor performance. Bioremediation is used as a practical approach to address pollution caused by arsenic. This study aims to determine the bacterial population of P. vittata with the potential for bioremediation of arsenic-rich soils and plant growth promotion. The 16S amplicon metagenomics analysis was employed to determine the composition, functions, and bacterial diversity of soils from arsenic-rich and natural mineral sites. Conventional methods were employed to isolate, screen, and identify bacteria potentials for plant growth promotion, arsenic and other metals tolerance, detoxification, and bioremediation abilities. The selected isolates were evaluated for their efficiency in mitigating the toxic effects of arsenic, plant growth promotion and enhancement of the hyperaccumulation ability of P. vittata under different arsenic stress condition. |
